Maximizing Ventilation for the Health of the Horse

ventilationWe recently wrote about muck pits and dealing with manure at horse facilities and received comments about stabling time; some saying that shorter times in stalls are better for horses. We completely agree. The longer a horse is stabled indoors, the more likely it is that the animal will be standing in urine-soaked bedding for at least part of the day. And we all know ammonia causes problems.

We want the air inside our barns to be as clean as the air outside the barn. Blackburn Architects’ designs stress aerodynamic ventilation, strategic natural light, and passive solar heating and cooling in our equestrian facilities.

When John Blackburn was beginning to design horse facilities more than 30 years ago, he found combining regionally-appropriate architectural elements with aerodynamic airflow principles created pleasing, healthy spaces for equines and their caregivers. Even early on in his career, heading into his barns was refreshing. “In August,” he has said, “in the dead of summer, when there was no wind – your hair would lift” from the natural ventilation created by the proper placement of the barn on a site, and the use of two engineering principles, which Blackburn Architects has employed in every design then and since:

1. The Bernoulli Principle – As air blows across a surface, e.g. a bird’s wing, it creates lift. Barn placement on a site is critical. If possible, a barn should capture the prevailing summer breezes (for horses you’re always more concerned with cooling rather than warming).

Inside the barn, air needs to move up and out. Blackburn frequently specifies ridge line vents in our designs. The vertical ventilation rids the barn of odors, pathogens and infectious bacteria that could otherwise be transported from horse to horse.

Even in cold climates like Montana, Blackburn Architects designs for maximum ventilation in the winter. “A horse gives off a tremendous amount of humidity; a lot of bacteria and in a contained area – like a stall – that’s an incubator for disease. I don’t care how cold it is where you live, you want to ventilate your barn year-round,” explained John Blackburn.

2. The Chimney Effect – Maximizing natural light in a barn creates a healthy environment by helping to “sterilize” the spaces. For example, as the sun moves across the sky and a band of light travels through a stall – perhaps through the upper portion of an exterior Dutch door left open – it helps to dry and evaporate urine. Blackburn Architects’ spaces have a lot of windows, and skylights. Vented skylights glazed with a translucent polycarbonate panel running the length of the barn are hallmarks of our barns. The light source provides a low cost, shatter-proof feature that diffuses the light, thus eliminating harsh shadows, which could cause horses to spook. “My barns are designed to function throughout the day without the use of artificial lighting, except in enclosed rooms such as bathroom/laundry,” John Blackburn explained.

“A horse is designed to live outside in the wild. If it wants to get out of the sun, it’ll run under a tree. If it wants to get out of the wind, it’ll run behind a hill. This natural, healthy way of living is what we strive to create with our barns so that our athletic partners have the best chance of long, healthy lives – indoors or out.”

Blackburn Barn Topics: Stall Flooring

Stall Flooring

In this on-going series, John Blackburn offers insight into component parts of equestrian facilities. With more than 35 years’ experience in the design of horse barns, he’s seen his share of good, bad and worse. In this installment, he gives advice on stall flooring. Still as applicable as ever, we’re reposting Sushil Dulai Wenholz’ article from The Horse, Sept 1, 2001 (added a few updates, too).

Stall Flooring
By Sushil Dulai Wenholz

You give a lot of thought to your horse’s health and happiness. You groom him until he gleams, swaddle him in boots and blankets, carefully monitor his diet, and expend considerable effort and expense making sure he’s comfortably bedded. But have you thought about what lies beneath that soft bed? In essence, the stall floor is the box spring beneath your horse’s mattress, and it’s every bit as important as what goes on top–perhaps more so.

No matter how nice the bedding, a poorly constructed floor can lead to respiratory troubles from ammonia gases, thrush from trapped moisture, achy joints from uneven or too-hard surfaces, and injury from slippery or abrasive materials. In addition, a poor floor can mean wasted bedding and extra labor for you.

A good stall floor starts with a good construction plan. John Blackburn, senior principal of Blackburn Architects, a 34-year-old firm that has designed more than 400+ barns in 35 states; and Peter Gibbs, Extension Horse Specialist at Texas A&M University, outline the steps involved in building a floor that will keep you and your horse happy, whether you’re revamping an existing stall or building a brand new barn from scratch.

Starting From Scratch

1. Pick the location. If you’re building a barn, you have the luxury of choosing the best site. Look for an area that’s dry or at least easy to drain. Avoid steep slopes, areas that are consistently wet, and locations that are subject to water runoff during heavy rains or snow melt. In terms of soil, you’re basically stuck with whatever is normal for your region. But if you have it, soil that packs tightly is ideal, says Blackburn, because it will provide a tough surface that isn’t too hard or abrasive.

2. Dig to the base. Whether you’re starting from scratch or redoing an existing stall, you need to dig down to a well-draining layer of soil. This will give urine and other moisture a path to drain away from your horse. Expect to excavate at least one foot deep over the entire stall, says Blackburn. You might have to go deeper, depending on local soil conditions.

3. Level the ground. You should level out that base layer to help make sure the surfaces above it are level. A nice, even plane puts less stress on your horse’s legs than an uneven floor.

4. Compact the base and fill. Even if the floor starts out flat, Gibbs explains that extended use can create a holey or uneven surface, especially with dirt or stone-dust flooring. To form a firm foundation that can withstand daily wear and tear for extended periods, compact the floor. You can use a hand roller, a motorized, hand-held compactor or “settler,” or some other heavy pounding tool to do the job.

First, compact the layer you’ve uncovered and leveled. Then begin adding layers of dirt or stone dust. “The important thing is to install the flooring in layers and tamp it at each layer,” says Blackburn. He recommends using three-inch layers for dirt or one- to two-inch layers for stone dust. Compact each layer “until you think it can take the abuse of hooves kicking at it,” he adds, noting that there isn’t a standard measure to go by.

To ensure good drainage away from the building, add layers until your floor’s surface is 12 to 18 inches above the natural grade around the barn, says Blackburn. “You want to get the moisture to drain through the flooring and away from the stall and barn,” he explains. In addition, this protects the floor from high water levels outside that might otherwise easily flood the stall.

Now you’re ready to add the floor itself. Next you’ll find basic installation information for several common types of flooring.

Adding the Flooring

Dirt–If you plan to have a dirt floor, and local soil drains exceptionally well, you’re done. Most soils, however, drain moderately well at best, so you’ll probably want to help it along. One option is to grade the top layer of dirt slightly (no more than three degrees), so that moisture runs off to exit the barn or stall through an outlet in the corner (or through the stall door to the aisle).

You could also make a “leach hole,” or simple drain, inside the stall. To do this, dig a hole about three feet in diameter and deep enough to reach that bottom, well-draining layer of soil at the base you created. Then fill the hole with varying sizes of rock (or alternating layers of sand and gravel), starting with large gravel chunks at the bottom and working toward stone dust at the top. Tamp into place and cover with dirt to even out the floor.

Stone Dust–Blackburn believes that stone dust (also known as crusher run, screenings, or quarter-inch minus) makes a better floor than dirt, “because it can compact well and still permits drainage.” However, he does recommend adding a subsurface drainage system to enhance flow-through. To do this, lay filter fabric over the floor, top it with a layer of crushed gravel, then add three to five inches of stone dust. As you did with the base, compact the stone dust after each one- to two-inch layer. When you’re done, water the floor, tamp it down tight again, and let it settle overnight. Fill in any holes or depressions the next day.

Another idea is to install a drainpipe under the stone dust floor. “I feel that this helps drain the moisture away from the stall area and allows you to flush the stall with moisture to cleanse the flooring,” explains Blackburn. “Otherwise, it could drain into the dirt and stone and stay there, providing odor and a breeding ground for bacteria.”

To lay pipe, first dig a swale–a sloped ditch about one foot deep. Lay perforated pipe into the swale (you want a piece long enough to provide drainage away from the building, notes Blackburn). Cover the pipe with filter fabric, then fill the swale with crushed gravel. Now add and compact your stone dust as stated previously.

Plastic Grid–Plastic grid flooring comes in many variations, but the basic idea is the same for all floors: To provide a 100% permeable floor plus a level, stable, durable surface. Installation instructions vary by manufacturer; however, most recommend laying the grid over a well-draining subsurface (such as stone dust) so that moisture not absorbed by bedding will drain away. Usually, the holes in the grid (which create the excellent drainage) are filled with stone dust.

Rubber Mats–As with grid systems, rubber mats (and similarly, rubber pavers, which look like rubber bricks) vary in design, thickness, texture, etc., from one manufacturer to the next. Likewise for installation instructions, although most want you to measure stalls so that mats fit snugly against each other and the walls. Unlike grids, however, mats and pavers are meant to trap moisture above the surface, where it can be absorbed by bedding. Moisture can seep through the seams (or possibly the rubber itself). So, flooring experts recommend that you lay mats over a well-draining subsurface, such as one of the crushed stone systems mentioned earlier, or over relatively nonporous materials such as concrete and asphalt that can be easily disinfected.

Asphalt–You can lay an asphalt floor yourself, if you’re willing to find a supplier, rent equipment, and learn the proper way to apply, rake, and settle it. However, it can be a tricky process. As Blackburn notes, “The right mix of asphalt is important. It should be raked as it’s installed, then hand rolled. I would imagine that hiring a professional would be advisable.”

He also suggests that you grade asphalt floors with a crown of one-eighth inch per foot in order to sustain drainage. “With a flat surface, the urine puddles and leaves the horse standing in dampness, potentially causing all kinds of hoof issues,” he explains. The slope will also facilitate drainage when the stall is washed or disinfected. Blackburn recommends the use of aggregate, or “popcorn,” asphalt, which offers a non-slip texture. And he strongly urges the use of rubber mats or rubber pavers to cushion this relatively rough surface.

Concrete–Many people are comfortable mixing and pouring their own concrete–an easier process than laying asphalt. For larger projects, you might want to hire outside assistance. Although moisture can seep through concrete over time, this footing is not as porous as stone dust. So, Blackburn recommends grading it at a rate of one-eight inch to one-quarter inch per foot to allow for drainage. Concrete should be cushioned with rubber mats or pavers, he adds, to reduce the risk of injury and musculoskeletal stresses that this hard flooring could cause.

A Note on Cost

Before you begin stall floor construction, you should create a budget for the project. However, as Blackburn notes, “The cost of different options can vary dramatically based on the number of stalls, location, and the material used,” as well as the specific suppliers, consultants, and equipment rental agencies with which you might deal.

For instance, says Blackburn, “I have found that the cost of asphalt flooring can range widely from area to area. And some suppliers require that a large quantity be ordered of the type and mix you need before they will supply it at a reasonable price.” Therefore, it could actually be more expensive, per stall, to floor a smaller barn than a larger barn. It’s important to contact local companies for estimates before you start the job. (For mass-manufactured, nationally distributed products like most rubber mats and plastic grid systems, you can check pricing with the manufacturers, many of whom have web sites.)

As you start compiling price quotes and creating a budget, Blackburn cautions that you consider not just the initial expense of purchase and installation, but also long-term costs. A dirt floor might be virtually free to install except for labor, but could be expensive in terms of labor over the long run. Rubber mats might be pricey at the start, but could pay for themselves through longevity, ease of care, and reduced bedding.

Also consider the stall flooring material can greatly impact the amount of bedding you’ll need to use. For instance, a stall floor with interlocking rubber brick can cut your bedding in half which can save on barn operations, offsetting increased installation costs.

Additional options for flooring include adhered cushioned or foam filled. To conclude, all stall flooring has an impact on the comfort of your horse, the material cost of installation, bedding requirements and your ability to clean and sanitize the stalls.

Dear John: Recommendations for Lighting for an Arena

arena lighting photo

Hi John. I hope you had a wonderful summer!

Q: Our covered arena has been put to good use throughout the last year, but we really need lights to make it even more beneficial to our program. Given your expertise and experience with equestrian barns and arenas, I was hoping you might be able to give us some guidance.

We are having a hard time determining exactly what kind of and how much lighting is necessary. Do you have a formula that you use?

Any help you can provide would be greatly appreciated. I look forward to hearing from you!

Best,
Undercover Rider

Dear Undercover Rider:

Glad to hear all’s well.

I would be happy to offer some guidance on lighting for your arena.

A: I typically recommend approximately 35 to 50 foot candles per sq ft of light on the arena floor in order to provide a sufficient amount of light for a variety of functions. It also depends on the amount of reflective surfaces you have and the color of those surfaces including the arena floor material.
If you are anticipating a variety of entertainment type functions such as charity events, parties, etc you may want to consider a variety of type mood lighting for different events.
There are also a variety of type lights to consider such as metal halide, LED, HD, etc.
There are other factors to consider as well such as initial cost, operating cost, maintenance or lamp life and also the design of the fixture (bird protection, fire safety, etc.)

We are beginning to use LED more often now. I hope that helps!
John

Designing For Extremes: Snow & Ice

Coming off the heels of a truly epic storm for the Washington D.C. area (and most of the east coast!), I thought I’d take a moment to address how design techniques can help barns “weather” extremes.

In the United States, the upper northeast regions through to the Midwest are prone to experience weather extremes in the form of snow and ice. While we cannot entirely “weather proof” a barn, we can make it more resilient to some of the more damaging effects of weather phenomena.

Barn In A Blizzard

The roof of your barn needs to be able to:

  • Withstand the weight of snow and/or effectively shed it
  • Prevent or reduce the formation of ice dams
  • Redirect “roof avalanches” from sliding into high traffic or poor drainage areas and also reduce associated noise that could frighten the horses.

In addition to contributing to the Bernoulli principle I incorporate for natural ventilation, steeply pitched roofs also contribute to effective, gradual roof shedding and the redistribution of snow load. Ideally the pitch should be between 4/12 and 6/12 to get the optimal shedding effect (although, we generally try to keep pitches at 7/12 or more to take full advantage of the Chimney Effect and Bernoulli principle for natural ventilation)

Roofing material will also factor into how the snow will shed. Metal roofs are excellent as they are smooth and slick. They will also stay colder longer; reducing the likelihood that snow will melt and form ice dams (more on this below). Snow will shed from a metal roof even if the pitch is lower. Shingled roofs, however, will slow down the shedding process by “holding on” to the snow and allowing it to stay in place and accumulate. Consider a steeper pitch if you prefer a shingled roof as it will facilitate the shedding process over the rougher material.

Now, you might be saying to yourself, “Well, the snow is off the roof…but it’s all over the place! Now what?” Including strategic roof overhangs will complement the steeper pitch by helping to distribute shedding snow away from exterior walls and out of traffic and poor drainage areas. Be wary though, snow sliding off roofs can be noisy and frightening to horses, not to mention dangerous if it falls on you! Snow guards on the roof can help reduce the noise associated with shedding snow and keep huge sheets of it from falling on (and potentially harming) 2 and 4 legged passersby. Gabled dormers over entryways can also be useful. They help to direct snow off to the sides.

Ice dams are another unfortunate side effect of snow-laden roofs. An ice dam forms when the underside of the roof gets warm enough to thaw the bottom layer of snow sitting on the other side. The water makes its way down to the eave where it refreezes, eventually growing into a mound of ice. As the ice dam gets larger, it can pull the shingles and edges up allowing water to get through and into the insulation and walls. Water damage then wreaks havoc on the interior of the barn. The ice dam could also break off the eave and take pieces of the roof with it or fall on passersby. Sure, there are ways to deal with ice dams once they’ve formed, but natural ventilation can help prevent them upfront. Natural ventilation keeps the underside of the roof within 10 degrees of the outside temperature, which aides in keeping that critical layer of snow right on top from thawing and running down towards the eaves.

Site and circulation planning can help prevent and/or reduce the impact of icy conditions around equine walkways. In the interest of horse safety, I try to design site circulation so that horses do not need to move over asphalted areas intended for trucks and service vehicles (there are other benefits associated with that as well). Asphalt is not great for horse’s knees, generally, but it is particularly problematic when wintery conditions lead to the formation of “black ice” — a thin sheet of ice over the asphalt that can be imperceptible to the horse or persons walking on to it. Horse pathways in and around the barn should include porous footing that absorbs and carries moisture away quickly. Presently there is no way (that I know of) to prevent pastures from freezing over, but you can maintain a dry paddock or “sacrifice” lot where your horses can be turned out when pastures have been effected by inclement weather. Paddocks with considerable slope can be particularly hazardous when they freeze over. That’s when a “level” dry lot can be very useful!

Caution!

 

As many on the east coast found out this past week, there is only so much preparation you can do in a couple of days before a storm hits. You, your horses, and your barn will benefit from built in preparation.

Ask the Equestrian Architect: What’s in it for Me?

I think that’s the top question I get (the gist of it, anyway) and it SHOULD be. Why should you hire an architect to design a horse barn? Or, Is hiring an architect to design a barn really necessary?

In short: no. However, hiring an equine architect can save you time, your horse’s health and safety, and even money in the long run. Allow me to state my case.

A horse is so much more than a pet: it’s a companion, a worker, a teammate, an athlete. Whether you ride for pleasure or compete, the horse—your horse—is irreplaceable. I wish not to gild the lily just to make my point, which you already know, that horse owners think the world of their horses and want to treat them with the utmost care and respect. If you keep a horse, it’s your duty to protect it. While a horse is perfectly pleased to graze outdoors most days, the barn is a necessity – so I say, let’s do our best to protect that horse and maybe make your life a little easier in the process.

"Barn? What barn? We're good right here."

Barn This Way – Product vs. Service

When you decide to build a barn, you have a few choices. The least costly solution is to purchase a prefab or kit barn. The prices range (rather wildly), as does the package itself. Labor is often an additional cost as well as nails, roofing, and concrete costs. Usually a contractor charges between 10 to 25 percent of the total cost of materials for construction services. However, this percentage may go up if your project is on the small side in order for it to be financially viable for the contractor. For many horse owners, a prefabricated or kit barn is a perfectly reasonable and cost-effective solution.

If you’re looking for a step above prefabricated, or can afford to customize your project a bit, you may then wish to research design/build contractors – but this is where I’d stop and suggest that you alternatively consider working with an equestrian architect.

Why? A design/build contractor is selling a product, not a service, and is not often a trained architect, which limits his or her ability to think creatively outside of the box. In most cases, thinking outside of the box eats up profits and costs more money (for the design/build contractor). For a design/build contractor, the goal is to build quickly above all else. I think this compromises your program and the overall result because the design/builder does not want to eat up time resolving special issues or conflicts. The design is usually cookie cutter, following whatever pattern the design/build contractor typically uses, and there is no one there to really represent the owner (you) and oversee the quality of the project and if it’s built as intended or promised.

To Serve and Protect

With an equestrian architect, you’re purchasing a service rather than a product. The architect is there to resolve the needs of the owner, from overall site planning, programming, phasing, and design to overseeing the entire construction to make sure the barn is built as intended. The service costs a bit more than a design/build contractor but, if your barn is your livelihood or your sanctuary, I believe that you’ll save time and stress, frankly by getting it done right the first time.

Typical services an equestrian architect (straight from the horse’s mouth here, if you’ll forgive my pun) will provide:

  • Site planning: can reduce infrastructure costs (fewer roads, less fencing, better drainage, etc.) and improve the site to function at its best for your needs.
  • Programming: ensures that the whole farm (not just the horse barn but the entire collection of structures on the site, if applicable: residence, guest house, caretaker’s quarters, hay/bedding, vehicle storage, etc.) operates efficiently and safely.
  • Code analysis: certainly the codes vary across states/municipalities. We’ve designed horse stables in counties with very specific codes and regulations and understand what to look for and how to work with the various officials to resolve issues. The architect can save you a lot of hassle!
  • Budget Development and Cost Control/Scheduling: I like to develop a budget as early in the process as possible and revisit it periodically during the project. My job is to determine if the owner’s programmatic needs and budget fit the site, and if the design aesthetic suits their personal design goals. We can also plan to develop the barn or various structures in phases, if applicable.
  • Conceptual Design: Here we develop the character and massing of the structure(s) and prepare a preliminary floor plan and elevations to illustrate our ideas. At Blackburn, this is the final phase of what we call Master Plan Services (site plan, written program, conceptual design, and preliminary construction development). From here, we move on to more detailed design work.
  • Schematic Design: After we complete a master plan that works well for the owner, we begin to prepare detailed drawings to give you an idea of the layout and general appearance of the barn (and possibly other buildings). We’ll talk about finishes, materials, stalls, tack rooms, etc. For a lot of people, this phase of design is the fun part!
  • Design Development and Construction Drawings: Here we’ll really start to nail down the final design and specify the materials, stall systems, finishes, and other details and prepare construction drawings that instruct the contractor how to build the barn.
  • Bidding and Construction Administration: Because construction drawings are open to interpretation, it’s important that the architect works with the contractor to oversee that the project is carried out according to the design intent. We’re the owner’s rep to make sure that construction is done well and done right.

I understand this may seem like a lot, but each is a valuable step toward designing a healthy, safe, and functional facility. As an architect, I want to study how you operate and design a barn that feels inviting and personal (because it is). No barn or farm operates exactly alike as each owner or barn/farm manager operates his/her facility in a particular fashion. While designing a barn from scratch is not realistic for everyone, if you are choosing between a design/build firm and an equestrian architect, I’d strongly advise that you approach both for more information and weigh out your options carefully. It could save you your horse.

As always, I invite your questions and comments. Thanks for reading!

Tidewater Farm

An architect is trained to design as the great Louis Sullivan (1856-1924) states: “Form ever follows function.” After all, if your barn doesn’t function properly, what’s the point of a great design?

Private Barn: Montana

Designed in response to an adjacent new residence and in the style of existing barns on the private ranch, this eight-stall barn in Montana uses heavy timber framing and western cedar siding.

The program includes wash and grooming stalls, a lounge/office, large tack rooms, and a loft with a balcony that overlooks an outdoor arena. The barn’s deep overhangs create covered areas to wash and groom horses outdoors while a continuous translucent ridge skylight allows generous amounts of natural light within the barn.

Program 8-stall barn, outdoor arena, service building

Completion 2004

A translucent continuous ridge skylight provides ample natural light within the barn's interior

Western cedar siding evokes a natural look so the barn may suit the landscape

The loft area has plenty of natural light while the deck is the perfect spot to relax and watch riders in the nearby outdoor arena

Being in the middle of nowhere sure has its perks.

First Barn: From just horsin’ around to designing barns

As a kid in Tennessee, I grew up around horses, though I had no interest in properly riding them. That I left to my twin sister, who kept her Tennessee Walker named Dixie in a neighbor’s barn. For me, playing in the barn’s loft for days on end in the summer was much more appealing.

I left Tennessee for Clemson University (B.A. Architecture, 1969), where I developed an interest in designing buildings inspired by context, environment, and function: I became a student of the philosophy that “form follows function.” There was no doubt in my mind that I had left horses and the barn behind. After all, I never aspired to be an equestrian architect. I was a student of urban design. Ironically, over 25 years later, I earn a living designing equestrian facilities across the country. That is because a single interview changed my life.

Following graduate school (Washington University in St. Louis, M.A. in Urban Design, 1973), I relocated to Washington, D.C. in pursuit of its urban and robust economy as a place to possibly support a future architectural practice. My former colleague, Robbie Smith, and I began “moonlighting” on small side projects together and decided to create our own firm. As young architects, we’d happily take any project we could get our hands on. So, when Robbie received a phone call from a friend in the summer of 1983 about a fairly large potential horse project in Upperville, Virginia, we jumped. Forget that we had never designed a horse farm, or, for that matter, any other building of size of significance on our own. We had nothing to lose.

The Interview 

Preparation began for the big interview. We learned that the owner, Robert H. Smith (no relation to my partner, Robbie Smith), selected the renowned landscape architect Morgan Wheelock of Boston to plan the farm. Together, the owner and Wheelock sought an architect to design the farm structures to fit within the well-known Upperville and Middleburg, Virginia context.

Typically, during an interview you review your firm’s portfolio of completed projects with the potential client. This was not an option for Robbie and me — we’d have to approach this interview differently. Since Robbie was from Middleburg, he was familiar with the area’s building types. He spent a few days photographing various buildings in the area — forms, materials, and shapes — that represented Middleburg or Upperville in any way. Barns were certainly photographed, but we also considered residences, commercial structures, and other miscellaneous structures relevant. With plenty of images to inspire us, we selected a number of key examples. Many of these buildings were perhaps a hundred years old and probably weren’t designed by an architect. However, we felt they strongly represented the area. We took the photographs and projected the slides on the wall of our small office, traced over them, and transferred the images to illustration boards to serve as our “portfolio” presentation.

I’m not aware of what the other interviewing firms presented, but ours did not include a single building we designed or were designed by any architect, for that matter. Our presentation documented the context of the area in a series of hand-drawn sketches — but, at least, if the owner’s farm were to “fit” into the context, these were the shapes, forms, materials, and scale they should have.

We were hired immediately. Suddenly, we found ourselves with seven buildings to design with no staff in an unfurnished office space in a third-floor walkup in Georgetown — and we weren’t about to complain. We were embarking on a project that would change our lives.

Horse Sense

Our client, Robert H. Smith, was a very successful developer in the Washington, D.C. area. While he had owned thoroughbred horses for several years, he stabled them at other farms or the track. Now he was ready to start a thoroughbred breeding operation, having acquired approximately 400 acres in Upperville, adjacent to the famous Rokeby Farm (owned by Paul Mellon) on one side and Route 50 on the other. Also included within the property were the grounds to the Upperville Horse Show, the oldest functioning horse show grounds in the United States.

Morgan Wheelock, the landscape architect, brought a background in designing horse farms to the project: with it, his theory that barn design, as well as the farm layout, should be driven by a paramount concern for the health and safety of the horse. The way the building is viewed and placed in the landscape, Wheelock believes, is as important as the design of the building itself. That’s because both the farm layout and the barn design impact the health and safety of the horse; concerns possibly even more apparent when operating a breeding facility for thoroughbreds.

Barns are often perceived as dark, dusty, and uninviting buildings. However, it’s also widely understood among equestrians that the best environment for a horse beyond the great outdoors is an environment that inspires just that. Wheelock bridged these inconsistencies with a design theory that focused on creating natural light and ventilation within the barn. It was a revelation. While the concepts Wheelock professed were simple, they worked — and beautifully — at our first barns at Heronwood Farm.

The barns at Heronwood Farm centered around two guiding design principles: a direct response to the health and safety needs of the horse and design wherein the shapes, forms, and materials are inspired and derived by context.

Completed Project – A Final Update on Family Farm in Marshall, Virginia

A few weeks ago, some of my staff and I were able to tour one of our recently completed projects, a new horse barn, arena, and residence (for which we did some renovations) in Marshall, Virginia. Marshall is located in the Northern Virginia piedmont, just outside of the well-known horse communities of Middleburg and Upperville. With beautiful, sloping land, the area is home to several farms, vineyards, and country homes.

The 8-stall barn has a lounge with an office on the second floor and an attached arena for the owner to practice dressage. I’m very pleased with how the new facilities have turned out and hope the owners are too. For more information on the scope of work, please see my previous post. [slideshow]
