Note: We recently received this question from a follower of ours on Instagram. While this is NOT a Blackburn-designed barn, we felt that others might have similar problems, so we wanted to offer as much help as possible to this horse owner. Some of her photos are included in the post for clarity.
Q: Dear Blackburn: We recently built a backyard horse barn in western Massachusetts. The timber frame style building is a hybrid run-in shed/horse barn, attached to a track-paddock with sacrifice areas and pastures. The horses are turned out together 24/7 with run-ins, with option of separate stalls if needed for injury/weather. This summer, after one year, we found mold in a few areas of the barn. Since learning about Blackburn, we have been fans, and we seek insights on how to remedy our mold problem in a way that is safe for the horses and hay too.
The barn is 36’x36’ with a raised center aisle. The south 1/3 of the building is a run-in with a packed dirt floor covered by rubber mats and shavings. The remaining 2/3 has a concrete pad and includes 2 stalls – one used as a horse stall and the other used to store hay. The 11’ ceiling leads to a hayloft (most hay stored in a separate building) with an 18’x6’ cut-out in the middle of the floor, for both sunlight and ventilation. Hayloft windows/door on all sides and an open eave towards the top also offer ventilation. A frost wall surrounding the barn is approx. 1’-2’ above grade. Inside the barn, including the run-in and both stalls, the interior frost wall was covered with resin technology wood screwed directly into the concrete, primarily for safety reasons, to soften the impact if a horse kicks the wall/concrete. We recently found black (and some white) mold between the frost wall and the resin technology wood. We have removed the product and bleached the area, but how to proceed…
1- How can we safely cover the interior concrete frost wall within the horse areas (run-in, stalls, grooming aisle, hay stall) so that it has some “give” to prevent injury when a horse kicks it, but which won’t harbor or cause mold? We have considered covering the frost wall with rubber, or adding a vapor barrier and applying new product.
2- What do you recommend we do to the concrete floor and frost wall to store hay and avoid mold in the hay stall? There’s a 4” step down from the aisle (we realize that was a mistake since it traps moisture). We put a high-quality insulated mat in the horse stall, but the concrete floor is bare in the hay stall. We use the hay stall for hay now but want to have the option of keeping a horse in there in the future. (We’ve previously stored hay on a double layer of pallets, plus floor covered by tarp, but with that set-up plus the wood product on the frost wall, the mold grew.)
MA Blackburn Fan
A: Dear Fan: While I don’t know for sure what’s causing the mold in your barn, I feel the application of the wood product directly to the concrete frost wall without airspace behind it and near the floor where it is subject to moisture may be the primary problem. I would suggest removing the wood product material at the frost wall and gluing rubber mats directly to the concrete frost wall to provide protection from horses injuring their legs by kicking the wall. Provide an angle crib guard along the top edge to help prevent cribbing by horses.
I am not that familiar with the product you used, but I know it is an engineered wood product that has a wide range of uses.
The fact that the barn doubles as a stall and a run-in shed indicates that it generally remains open which is good as it allows air to circulate in and through the barn and reduces the health hazard that might be caused by the mold.
I found it odd to see diagonal framing in the walls between the post framing. I’m unsure why that was done (maybe to provide horizontal bracing for the timber frame) but because the lower portion of the wall appears to be covered with the wood product it is possible air spaces between the diagonal wood framing trap air in some of the smaller spaces. That could add to the moisture build up. How the barn is maintained (i.e. washing down of the aisle and stalls), is handled could also contribute to the moisture problem. It appears from your photos that most of the dark staining (mold growth) is along the low portion of the wall at the frost wall and that is probably more a problem of the wood product panels being directly attached to the frost wall than the diagonal framing.
Regarding the hay storage, you should always store hay off of bare concrete. Using wood pallets is a good way to allow air to circulate around and under the hay. Hay gives off heat as it cures and if not properly allowed to breath can actually ignite through spontaneous combustion and cause a fire. Having the barn largely open as a run in shed is helpful but at a minimum the hay should not be stored on the concrete floor. It should also be stored off the wall several inches to allow the air to circulate around it. Placing a tarp on the concrete floor as mentioned will not serve any constructive purpose in my opinion and could just trap moisture below it.
BTW, I didn’t see any drains in your stalls? How do you encourage water out of the stall where the slab is depressed 4 inches?
Incidentally, I noticed a door hook on one of the larger sliding doors at the run in portion of the barn. That’s a potential hazard. A horse could rub against the door jamb and the open hook could cause a significant injury. I’ve seen it happen and it can easily be prevented. Another type of latch should be used. There are lots of options out there.
I hope this is helpful.
Whether for a horse barn or riding arena, there are a lot of things to consider in the slope of the roof.
Curious about recommended roof pitches in a riding arena? Senior architects John Blackburn and Ian Kelly advise that “a 4:12 pitch is pretty much our recommended minimum on any horse structure. We prefer steeper roofs for a natural chimney effect. However, unless you live in a cold climate where there is a lot of snow, we wouldn’t advise going taller than 6:12.”
The numbers indicating a 4:12 roof pitch mean the roof rises 4 inches in height for every 12 inches, as measured horizontally from the edge of the roof to the centerline.
Okay, so for barns our rule of thumb is as steep as you can make it. The steeper roof allows the Bernoulli principle and chimney effect to work more efficiently and effectively. But there are other considerations in designing the slope of a barn or arena roof.
For arenas, steeper the roof = the taller the building. This impacts the look or mass of the arena on the property which can be negative. It can stick out like a sore thumb or look like an airplane hangar in your backyard.
Because we depend less on natural ventilation in indoor arenas than in barns, we can get away with lower slope roofs. However, we don’t recommend lower than 4:12 if at all possible. We realize some HOAs and neighborhoods have severe height restrictions and the wider the arena, the more difficult it is to comply without “flattening” the roof. At Winter Farm in Peoa, Utah, we designed a low roof to stay within an imposed limit. In some areas, arenas may be considered agricultural buildings and therefore exempt from height limits. But that rule isn’t consistent across state lines or jurisdictions. For example, in one jurisdiction we were permitted a covered arena as a “sun shelter” and avoided building height limitations entirely.
Because arena walls at the perimeter are usually 16’ tall (need head clearance for horse and rider on interior below the structural frame), when the roof is a low slope, the roof becomes less visible as you get closer to the building and the building can look like a huge box.
You can make a huge box look great but that may require a lot more money and you typically want the arena to be in the background. The barn and the farm are the main focus and not that big ugly box on your farm.
One way we reduce the impact of the arena size is by pushing it into grade where we can, using the land contours and landscaping where possible, and placing it behind the barn and other structures to reduce the scale of the building.
Probably the best average height for a barn is 6:12 to 7:12. The reason is it is more difficult for a roofer to walk on a steeper roof without some sort of support. Thus the installation time increases dramatically as will the cost if it is built with a steeper roof.
One of the down sides for low slope roofs in snow climates is snow loading. A steeper slope can be designed to shed snow pack better than a low slope but the downside for that is the avalanche effect. When it melts it can fall fast, be loud and block doorways… a subject for another blog post!
Let’s talk about dry lots. Essential on nearly every equine facility, dry lots vary widely in size, location and construction.
By nature, of course, horses are herd animals evolved to roam and graze on sparse prairies. We’ve introduced a complete change to the evolutionary process – incorporating diets of grain and lush pastures. The resultant problems are many, but our solution is simple. Limit the horses’ activities or diet as you give them access to open air and light.
Blackburn recommends dry lots on most, if not all, of the farms we design. Sadly, too many farms have unintentional dry lots because of inadequate pasture management.
Why create a healthy dry lot?
1. Control the horse’s diet.
2. Preserve paddocks thru rotation.
3. Control moisture and its effect on hooves.
Here are nine things to consider:
Location: Choose a place close to the barn for ease of access. Provide adequate sized gates for horses but also an occasional vehicle. Select a relatively flat location but one that drains well and isn’t too isolated so horses can socialize but generally remain separated.
Materials: The footing should be firm but not hard packed. It must be designed to drain well to allow moisture to either drain thru or away without causing erosion. Sandy soil is preferable but some sort of gravel that is easy on the feet or, even better, an engineered footing similar to your arena should work perfectly.
Size: The size can vary, but if you are creating the dry lot to limit the horses’ movement for health reasons, you may want it to be smaller than larger. We recommend multiple dry lots of varying sizes to accommodate many uses.
Fencing: It goes without saying that your fencing needs to be sturdy. See Activities below.
Shelters: Some form of shade shelter for fly & weather protection is preferred – by humans, but horses may never darken the interior.
Feeding: Various forms of slow feeders, salt blocks, etc. can be used. If you are restricting the horse’s diet, we recommend consulting with your vet about setting up a feeding regimen that can be incorporated into your use of the dry lot.
Activities: Spreading hay rations around the lot encourages movement; toys for activity or human interaction can be very helpful. We always recommend consulting with your veterinarian because no two horses are the same. You and your vet know what’s best for your horse.
Socialization: Locating the dry lot close to other horses reduces stress and is more emotionally relaxing.
Footing: The dry lot surface should provide a safe and comfortable footing for horses but it must also drain well. Therefore, we recommend that the upper surface/footing be 4 to 6 inches of footing material (stone dust, sand, engineered footing material as described above a drainage layer) or possibly 8 to 12 inches of pea gravel, allowing the foot to sink in without undue pressure on sensitive areas. The drainage layer can be 1/2 inch to 1 inch stones. You can add an interlocking grid within this layer to provide additional stability of the base layer and improve drainage.
One of the design considerations in nearly every Blackburn equestrian project is ground surface materials to be used at the exterior of the barn. Hopefully, the information below will be helpful in planning for your barn.
First consideration is it to be porous vs. non porous?
Either will work in this application but you need to build in some sort of drainage system for both, either on the surface or below the surface.
1) Interlocking rubber brick pavers. The Blackburn Architects’ team opinion is that this is the best all-around flooring system for horses because of its durability and aesthetic options. It’s slip resistant and holds up to abuse and in a wide variety of environmental and weather conditions. It can be set loose on a porous or non-porous sub-base or glued down on a firm base like concrete.
2) Oil base chip and seal: Chip seal is a surface treatment used on light traffic roadways/driveways, some lead paths and other areas used for horse or farm traffic. We do not use it very often anymore due to some environmental concerns in some jurisdictions (it typically requires a base layer of asphalt and oil as a binder). Chip seal basically combines one or more layers of asphalt with one or more layer of aggregate. Oil is often used as a binder. Ground up recycled tires are sometimes used as an aggregate. It tends to be slip resistant though it may deteriorate in time. Its life time is typically 5 to 7 years before it needs re-surfacing.
3) Rubber mats (loose laid or glued): This is a good material but should be laid or glued to a concrete or popcorn asphalt base. The mats need a solid base in order to hold in place or remain level over time. Rubber mats can present an aesthetic issue but functionally work well.
4) Stone dust or brick dust: A good material to use but requires maintenance to retain a clean and orderly look. It’s slip resistant and drains relatively well. Not good for plowing conditions unless it is re-spread at the end of the winter season.
5) Popcorn asphalt: An excellent material because it’s slip resistant and drains well. Its problem is its aesthetic appearance. It should be laid over a layer of crushed gravel so the surface water can drain through the asphalt and away. The advantage of the popcorn asphalt is it has the ability to reseal itself in warm weather if the ground freezes and heaves. It can also be used as a base layer under rubber mats or rubber bricks.
6) Concrete (custom colored and/or textured) or concrete pavers: Not a very horse-friendly material to use. It can be scored to give it texture, tinted to give it color and in some cases a brick pattern, but it is nevertheless a very unforgiving material. Horses shoes can slip on it and spook a horse especially when crossing from one material to another. However, this material is great when installed under the interlocking rubber brick or rubber mats.
7) Poured in place non slip surface material: This is a good material (a number of different types and manufacturers available) that can be slip resistant, cushioned to protect from a fall and can be used outdoors. It is often used on playgrounds. Blackburn Architects uses it most often in foaling stalls where a seamless continuous surface is desired.
8) Grass ground cover: Not recommended due to its maintenance needs especially when under cover.
9) Grid mats: Can work if the owner wants to use stone or brick dust or some other type of light screenings but requires periodic maintenance.
10) Brick or stone: Not highly recommended as it is less slip resistant though it can look great, especially if brick dust is used elsewhere such as the driveway in a chip and seal application.
Over the years, Blackburn has been asked what we think of adding stalls along the side of an indoor arena. Sounds like a good idea, right? Well, we strongly recommend against it. The problems are many.
1. Air Quality. Forced to breathe arena dust many hours of the day, stalled horses live in an environment that isn’t healthy. We recommend instead that the stall portion of the stables be connected in a separate but attached structure running perpendicular to the barn. Not only does this arrangement help isolate the arena dust from the barn, it allows the barn to sit independently. The structure can then catch the prevailing breeze which permits two scientific principles (Bernoulli principle and the chimney effect) to provide natural ventilation and light to the barn.
2. Fire Safety. We always recommend fire separations by providing sliding doors to isolate the barn from the arena in case of fire. These doors may or may not be rated fire separations. The decision is usually driven by cost, and we often provide an automatic rolling fire rated shutter to isolate the two separate areas – this at least reduces the risk of smoke moving between structures. (Quite often it’s the smoke that is more dangerous and faster moving than the actual fire.) The isolation by sliding doors also provides critical time to get horses out of barn. If the arena and barn share the same space, there is less opportunity to isolate fire or smoke from the stable area. Furthermore, when the stables are parallel and part of the arena, the structure is generally shared – raising the risk it could collapse and trap horses inside.
3. Cost, Scale and Building Height. When stalls are designed as part of an indoor arena, the design requires a wider structure (often steel due to the long spans) which is typically more expensive. When it’s a separate but attached structure, it can be framed in wood with smaller spans reducing the cost of the framing. If the stalls are part of the indoor arena, then the building becomes wider which also means a corresponding height increase. In many areas, the local zoning codes restrict building heights. We have found typical restrictions of 35 feet. It’s difficult to get any height in the barn or arena if you are trying to build a 100 x 200 ft arena with a row of stalls and aisle way. Also, from an aesthetic perspective, wider and taller building begin to get enormous and have the potential to look like an airplane hangar and overshadow the entire farm.
4. Storm Water Issues. Finally, if your property is not flat, such a structure with a large footprint may require significant grading that can be expensive and create storm water issues. By breaking the barn and arena into two connected structures you can more easily work it into the natural slope of the land. Also, the isolation of the barn and arena permits opportunities to push the arena into the ground – helping to reduce the scale and height of the arena above finish grade. The entry to an observation area can be elevated above the arena floor (but entry level still at grade) for more easily viewing over the kick wall from a sitting position.
Blackburn has designed many arenas with this perpendicular arrangement. Rocana Farm, designed by us in 2002, is a great example of what we mean. Stalls at this hunter/jumper facility are attached to the enclosed arena with an elevated observation room, tack room, wash and grooming stalls.
Today I got a call from a client who’s buying 120 acres in North Carolina and plans to build a new equestrian center. It’s been years since horses have been on the property. The pastures and paddocks are overgrown. The fences are in disrepair. The property has steeply sloped areas but the client wants a dressage ring. Drainage will be an issue. Together, we’ll figure out a way forward by starting with a Site Plan to map the future; completing the owner’s vision in budgeted stages over several years.
A site plan is completed by studying topography, wind and solar directions, neighborhood easements, height restrictions, zoning restrictions, soils and operational necessities (where are roads, pastures, barns, storage sheds, etc.), There are many benefits to putting together this “roadmap” for future use of the farm property. Consider that there are three major categories of costs when planning to bring horses onto your property: 1. Operational, 2. Environmental, and 3. Infrastructure. Proper planning will save you money in all three areas. Fewer roads, less fencing, better drainage all ensure that the whole farm, not just the horse barn but the entire collection of structures on the site, operates efficiently and safely.
Operational Considerations: First locate where you’ll put the horses – where is your turnout? Where will you store hay, equipment, or vehicles? Do you have access for manure pickup, large-truck deliveries, guests or visitors? Minimizing the number of steps necessary for your daily routine (turnout, stall mucking, etc.) will save labor time, which of course you know is money in the farm biz. Planning will also preserve space for paddocks.
Environmental Considerations: Figure out structure placement within your acreage. It’s important to properly orient any new buildings in the landscape. We design our barns to generate their own ventilation, placing them perpendicular to prevailing summer breezes. (One of many design considerations for maximizing light and ventilation, which is a subject I’ve written about often.) Additionally, placing structures where the land will drain easily makes good sense and will save you and your horses potentially hours of muddy misery or the cost of constantly replacing eroded footing.
Infrastructure Considerations: Fewer roads to maintain means fewer dollars spent.
Creating a master plan does not mean that every part of it needs be built at once. The plan may end up taking years to implement, but as each new structure or paddock is added, it isn’t done in the usual haphazard way. It will save you from asking, “You know, I could use a tractor shed somewhere?” Even those with very limited budgets should consider getting the advice of an expert at the planning stage, given the importance of the optimum farm layout.
Bringing in a professional to carefully plan a site doesn’t mean you need to commit to having a custom barn designed. Blackburn Architects’ guidance can help whether you’re purchasing a kit barn, designing a custom barn, or renovating existing structures. A site plan stands by itself as a service we greatly enjoy delivering to clients across the country.
I’ve always made it a point to use passive renewable design elements and sustainable materials in my equestrian designs. The motivation is designing for the health and safety of horses, so it’s not surprising that what’s recommended for creating human and eco-friendly structures is also recommended for equines.
Nowadays, Blackburn Architects’ team rarely encounters a client who isn’t enthusiastic about including sustainable design principles in their farm program. With green technologies evolving every day, there are more systems and product choices available to suit the unique demands of equine properties. The most prevalent elements include natural light and ventilation, recycled materials and regionally sensitive natural woods and products.
SUSTAINABLE BUILDING MATERIALS
We incorporate recycled and sustainable materials into the firm’s barn designs. We’ve used recycled rubber bricks and pavers for aisle flooring, and recycled rubber mats for stall floors, and occasionally, stall walls. Not only are these products more comfortable for the horses’ legs and knees, but they also provide a slip-resistant surface. As for building materials, we use everything from FSC (Forest Steward Council) certified lumber and recycled steel to fly ash concrete blocks and recycled wood.
However, we are always mindful of what some recycled material mixtures contain. Some products include substances (plastics, resins, binders, etc.) that could be toxic to horses through off-gassing or if they chew on the material. If you’re designing your own facility, be sure your builder is familiar with the materials ahead of time and is comfortable working with them. Occasionally, we’ve run into a situation where the builder is unfamiliar with a product recommendation and accidentally convinces an unaware owner to use a product that may exhibit these harmful qualities.
BUILDING FOR CLIMATE
It’s important that building materials make sense for both the design and the climate. In more northern locations, we try to design with timber that will provide more insulation for the structure. In the south, a masonry-style building helps keep the structure cool and is more resistant to humidity and insect infestation. While bamboo is an excellent renewable resource option, it’s not often locally sourced and can be costly to ship. Douglas fir and southern yellow pine are the typical go-to lumber products for our firm. They are quality assured, sustainably harvested, and regionally sensitive. When combined with low VOC (Volatile Organic Compounds) finishes and paints, these materials make for sturdy, sustainable buildings that do not sacrifice quality or aesthetics.
Conserving water is imperative to any agricultural property, and there are many top-to-bottom green approaches to consider. It’s crucial to intercept and collect storm water before it becomes ruinous run-off that can affect ground water and nearby ponds and streams. We frequently use porous or “popcorn” asphalt for interior and sometimes exterior floor covering. It’s “self-healing” and aids in water drainage.
Since many horse farms around the country face changing weather extremes (torrential rain and drought come to mind), rainwater collection systems are vital for alleviating the resultant water issues. Roofs can be designed to route storm water into cisterns. The harvested water can then be channeled into irrigation systems for fields, paddocks, arenas and pastures, or collected for controlled distribution to prevent muddy conditions.
ACTIVE RENEWABLE SYSTEMS
In addition to passive systems, I highly recommend including active renewable systems in the design of any horse farm. The beauty of equine and agricultural properties is that they often feature characteristics that compliment these systems. Large swaths of land can facilitate geothermal power systems or wind-powered generators and other equipment. Roofs with large surface areas are common features of many agricultural buildings and make perfect platforms for solar panel systems.
One of the firm’s current projects is an extremely energy efficient property in Missouri. While targeting net-zero energy use, we’ve included a geothermal heating system and solar panels that power infrared heaters in the wash stalls.
Green technologies have come a long way and today’s solar panel systems offer more choices for collecting and storing energy. If designed properly and in the right location, it is often possible to fully rely on the solar panels for all your energy needs. Including these systems in conjunction with natural light and ventilation could conceivably eliminate outside energy dependency for your equine buildings. Over time, solar panels will pay for themselves in savings. Check with your local and state government about tax incentives for incorporating green energy saving systems into your property.
FRESH AIR AND NATURAL LIGHT
Accomplished with steep sun-heated roofs and vented skylights, the combined effects of the Bernoulli Principle (an equation of vertical lift championed by Dutch-Swiss mathematician Daniel Bernoulli) and the chimney effect (air pulled in low and vented up high) circulate fresh air throughout the structure while flooding the space with natural light. This method provides the optimal environment for horses because it turns the typically static barn into a machine while imitating the equine’s natural environment. The process significantly cuts down on the cost and operation of electric lighting and fans and the health and safety risks they can create.
One of the challenges we sometimes encounter with clients is convincing them to include active systems in their design programs. This is usually due to upfront costs. The price impact can be minimized by smart design decisions. Knowing ahead of time what green options are available and which ones you’d like to incorporate will inform your budget early on and, if need be, help you plan the property with future installations in mind.
THE BENEFITS OF COMPOSTING
Composting is another great passive renewable option. We strongly encourage all our clients to include a composting system in their design program. Composting helps manage muck and removes harmful bacteria and other organisms to create natural fertilizer for paddocks. It also helps keep organic material that could produce harmful uncontrolled run-off out of landfills.
Sustainable barn design is about what’s healthiest and safest for your horses. Remember, horses were never meant to be inside. But if they’re going to be, then it’s important to create an environment as close as possible to what they would encounter in nature, using materials and techniques that at the same time don’t harm the very environment they come from.
I thought I’d take a minute and explain Blackburn Architects’ process for designing a new equestrian facility and overseeing its construction. While not carved in stone, for planning purposes, can easily become a two-year process.
The first step is usually a visit by me or another Blackburn architect. The initial meeting is our first chance to meet, walk the site, look at any existing buildings and discuss the project goals. I’m a firm believer in “a picture is worth a thousand words” but “being there is worth a thousand pictures” Following this, we’ll send a proposal for service, which outlines the process and fees.
Once a contract signed, we get to work immediately.
The timeline usually looks something like this:
• 6 to 10 weeks for Feasibility Study, Site Assessment and Master Plan
• 1 to 2 months for Schematic Design
• 2 to 4 months for Design Development and Construction Drawings
• 1 to 2 months for Permitting
• 12 to 16 months for Construction
At Blackburn Architects, equestrian design starts with the horse and ends with a building that fits the horse, the owner, and the surrounding environment like a glove. It’s as simple and beautiful as that.
Let’s explain the steps in greater detail:
Feasibility Study / Site Assessment / Master Plan
The goal of the Feasibility Study is to determine, as early in the process as possible, whether the intended project fits the owner’s program, the site, and the budget.
We assess any existing building(s) and the site. We take measurements to determine if an in-place structure will work for the goals of the project. We study the land until we come to a clear understanding of wind and solar direction, soils, changes in elevation – all natural and architectural characteristics that guide placement and design of any new buildings. Central to the success of the project, this “Master Plan” addresses all these things and more, providing a road map for the success of all future phases of our work.
The site analysis also includes a review of applicable zoning and easements for the property; we determine what (if any) limitations or restrictions may apply at the property. Land disturbance allowances? Height restrictions? Set-backs?
In tandem with the site evaluation (as soon as we have a contract), we send the client a unique Blackburn Architects questionnaire that we’ve developed over the years. Answers are collected and inform the design; starting off the process with clear direction from the client. It is extensive and though it covers about 25 pages, once it is completed it “paints” a picture of exactly how you would like your farm to operate. The efficiency of the operation is critical and can have a huge impact on your operating cost and maintenance budget.
Moving seamlessly from the master planning phase (often there is a fuzzy line here where one ends and another starts), we start schematic design. In this step, we help our clients visualize the project design with a variety of techniques using both computer and hand renderings to illustrate the scale and the relationship of the project elements. Ideas, concepts, goals take form at this stage.
Once we’ve worked up outline specifications for the work, we can begin to get a rough idea of the costs. At this point we will either develop a rough estimate based on our 35 years experience with over 300 farm projects, consult with a professional cost estimator or a builder who is familiar with the building type in your location.
Design Development and Construction Documents
Once we have the site layout, design, and budget, drawings and other documents give serious form to interior and exterior finishes, and firmly establish the size, character, and details of the project. These documents will be used by our professional consultants to design the electrical, gas, and other utilities. When these systems are defined, and we have a basic finish schedule and budget, we’re ready to file for the permit and start construct of the building.
Bidding and Construction Administration
With the construction documents complete, we can help clients select a contracting company through a “bidding” process for the work, or we can work with a client’s pre-selected Construction Manager. We work side-by-side with our clients to ensure that the best and most informed decisions are made during this process.
While in my experience this process typically lasts about 18 to 24 months, a lot of this depends on factors that are outside of either our control or our clients. The time of year and weather, for instance, can greatly influence how fast construction progresses, especially in colder climates. Pastures have a growing season, and they need at least a year (maybe two) to establish.
Designing and constructing a custom facility is a very subjective process, which is guided by all kinds of factors including the complexity and size of the structures, the time of year, the strictness of zoning regulations and neighborhood associations, state environmental regulations, and so on. But rather than let these things hold you back, I say, “Jump In” or give us a call to discuss how the process can work for you. When you slide open the doors to your dream facility and see the happy heads of your horses looking over the stall doors, all the time and effort will vanish. At least that’s been my privileged experience over all these years.
Q: We’re renovating our fireplace, and want to incorporate the exposed fireplace flue shown in your German bank barn renovation. Where do you get the pipe for it?
Dear Barn Enthusiast,
Congrats on your barn conversion! We love breathing new life into these wonderful structures. To answer your question about the flue we used, It’s a galvanized steel flue, 12”-14” in diameter, and came in about 4 foot sections. It should be pretty easy to find. Stainless steel is another good recommendation and look. Galvanized is a little less expensive, but a little more rustic.
Hope that helps! Good luck with your project.
Pat Raia’s recent article about the California barn fire blamed on exploding manure raises legitimate concerns about the dangers of improper waste management. Standing piles of manure contain rapidly reproducing bacteria and methane gas build up (as the internal temperature rises you might see smoke rising off the mounds!). The impending “explosion” could ignite any combustible material in proximity to it and you could be left with a devastating mess similar to the California barn fire.
Manure storage in the barn is a fairly rare occurrence in my experience and I agree with the recommendation that it should be stored outside and away from the barn. Not only to reduce the catastrophic events that could be caused by spontaneous combustion, but also to prevent flies, mosquitoes, and odors (not to mention the unnecessary risk to the safety of the horses from outside service vehicles and haulers tending to it). I find that most people store their manure in a dumpster or muck pit. As an alternative, I recommend and frequently specify a composting system close to the barn. A composting system like O2Compost is great and can be designed to accommodate large to small horse barn operations.
They’re also compact, customizable and can quell the influx of flies and mosquitoes. The heat created by the decomposing manure “cooks” it until it is reduced to a manageable amount. It can then be used in more productive ways such as providing fertilizer for the farm and paddocks (the cooking process has killed the harmful bacteria by this stage) and preventing weeds. Always be cautious, though, when handling or transporting waste materials so as to avoid mixing with other combustibles. This could increase your risk for fire as well. Most farms do separate them because the hauler typically objects to combining other trash with manure.
Spontaneous combustion is not limited to manure, however. Hay is a serious factor where barn fires are concerned, in my opinion. It is all too frequently stored in improperly ventilated barn lofts where it can easily ignite. Unfortunately, many owners house their horses alongside hay storage and have no idea how potentially deadly it can be. They think it won’t happen to them. With daily convenience in mind, I usually design a ventilated, isolated area to accommodate only a week’s worth of hay storage at a time. Generally, hay should not be amassed in lofts, but whenever it is stored there it should only be in small quantities. Special precautions need to be taken such as installing alarm systems and reducing exposure to electric lighting and equipment. I recommend natural lighting through a skylight or clerestory windows. I strongly encourage installing a sprinkler system in the barn. I know it’s expensive but think of it this way, “ can you afford to lose your barn, your horses, and everything else in there?” It may be worth the investment considering what’s at stake.
I want to thank Pat Raia for writing the article, as it will, hopefully, raise our collective consciousness to the presence of latent hazards around the barn.Whenever designing for horses, my goal is to find every way possible to make the barn (and the entire farm for that matter!) a safe and healthy home for them and their handlers.
