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.
Fire protection in an equestrian facility is always a concern of the highest priority. Because we’re often asked, we thought we’d offer information here on the fire suppression details the Blackburn design team has included in some of our latest projects.
At a new barn under construction in Indiana, we’ve specified a Dry Pipe System by Fire Tech, LLC. http://www.firetechstl.com/systems-preaction.php. We could have specified a “preaction sprinkler system,” but chose the dry pipe system because of the dangers of freezing pipes in the cold weather climate of the Midwestern United States.
To quote Fire Tech’s description, “A Preaction Sprinkler System is a system which employs automatic and closed-type sprinkler heads connected to a piping system that contains air (either pressurized or non-pressurized), with a supplemental system of detection serving the same area as the sprinklers. The systems are typically used in applications where the accidental discharge of water would be catastrophic to the usage of occupancy.
“Preaction Sprinkler Systems are similar to Dry Pipe Systems in that the water is kept from entering the piping valve, in the case a preaction valve. This valve is held closed electrically, only being released by the activation of the detection system (heat or smoke detectors mainly) when an electrical signal is sent to the releasing solenoid valve. The water then fills the pipe, ready for the activation of the sprinkler heads. Preaction systems can be arranged to be activated by only one detection device type, or many.”
In Indiana, our architects specifically called for a dry pipe system because of the potential for freezing temperatures, but also in case “one of the children kicks a soccer ball and takes out a sprinkler head” (the client’s words). With a dry pipe system, the sprinklers won’t go off unless they also sense smoke or fire (depending on the detector type). A false alarm could flood and ruin the barn’s expensive finishes. And using recessed/concealed pop up heads is a good idea where you can.
Another critical reason Blackburn specified a dry pipe system is because of an issue with water demand; the Indiana farm doesn’t have sufficient well water on site to power the system. Because of this, our client connected to county water. Keep in mind that If you’re on a well, you’ll likely never have enough pressure to support a fire suppression system. The gallon per minute (gpm) for firefighting is higher than your average ground well can produce. This means you must store water on site in a tank or pond.
At Sheik Island, one of our projects in Florida, we stored water below ground. In California, at a private facility, we installed an above ground tank adequate to run the system as required by the local fire department. Additionally, we posted signage limiting the occupancy (should the owner decide to sponsor a large event in the arena). The clients obtain a special permit when larger events occur, and they hire the local fire department to have a truck on hand during the event.
At the Devine Ranch, in Aptos, California, and at the Moss residence, also in fire-prone California, we provided on-site storage tanks with backup generators to operate a pumping system.
Next up on the Blog: fire limiting design guidelines we build into our projects.
Fences are one of the most common discussion points among the Blackburn team and clients when we’re designing an equestrian facility. The options listed below are certainly not exhaustive but reflect what we commonly find in many of our projects.
Some options are better suited for pastures, while others are more appropriate for small stall turnouts. We’ve tried to identify a variety of approaches that meet the safety needs for horses, limit maintenance needs, and often fall within neighborhood guidelines.
1. Steel rail fencing is an option for stable turnouts. The material is available in a thinner profile so it isn’t as visually heavy and it can be painted black or another dark color so that it does not have the “ranch” appearance seen with galvanized steel pipe corrals. The up-front cost is higher but the material is durable and will have little-to-no maintenance needs.
2. Woodguard polymer coated wood fencing is treated wood with a non-toxic, non-chipping surface covering. The wood grain is still visible but the finish has some of the plastic texture of the polymer. This product allows for fencing to be constructed similar to a wood fence, with the rails attached to the face of the posts. The result is a stronger, safer fence. Woodguard has a 20-year warranty. The cost is similar to wood board fencing but the maintenance needs are less. While the manufacturers state that this product is resistant to cribbing, we would recommend that a hot-wire be provided at the top rail to discourage the horses from chewing. This material would be acceptable to use for both stall turnouts and paddocks. It offers the appearance of a traditional 3- or 4-board wood fence without the significant maintenance demands. https://www.wood-guard.com/horse-fencing/
3. High Tensile Polymer (HTP) comes in both rail and wire styles and is typically mounted on wood posts. The rail is typically 5” wide and from a distance will appear similar to wood board fencing. Because wire fencing has a lower visibility, we suggest using a thicker top board so that the horses can more easily identify the barrier. The HTP materials’ inherent flexibility makes these products durable and resistant to horses leaning on or running into the fence. Typically, these are more suited to large pastures or for perimeter fencing and less so for stall turnouts. The darker colors tend to exhibit a chalky appearance over time.
4. Rubber fencing is a durable, flexible, and low profile fencing material and is similar to the HTP fencing. We’ve not seen this product used as often and we understand that there’s a risk that the strings of the fabric (which is an internal support for the rubber) can become exposed and offer a hazard for horses to chew on. A hot-wire at the top of the fence may combat this risk.
The advantages of rubber, HTP or any type strap fencing is the posts can be set further apart which is useful when its highly visible and you want to minimize the number of posts. The fencing is flexible and resists breaking when a limb or tree falls on it therefore it’s a good material for perimeter fencing large acreage and where it encounters wooded areas. This is safer if/when a horse runs into the fence; especially a problem on larger paddocks when horses can get some speed and not be able to slow down.
5. HDPE is a post and board fencing material. It’s stronger than PVC and performs better in all weather conditions, but the primary issue is in the assembly of the fence. The rails are set between posts, instead of fastened to the face, and can pop out if the fence is not secured properly. Its requires more frequent posts which tends to look busy and it’s difficult to bend or angle corners because of the assembly method. The Blackburn team isn’t particularly fond of this material because it can look clunky and isn’t the safest option. http://www.amberwayequine.com/products/hdpe-fencing-2/
With careful attention to design details, it is possible to retrofit your barn to be healthier for your horses. One important renovation to existing built structures is the addition of skylights and ridge vents to increase light and air flow.
Only a fortunate few horse owners design and build a barn from the ground up. Most buy a property with an existing barn. As the photos illustrate, Blackburn Architects’ client Kevin Plank, the CEO of Under Armour®, bought historic Sagamore Farm in Maryland, and undertook a significant renovation to add light and ventilation to the interior of his historic main barn.
Significant expenditures are not necessary, however. In this discussion, I’m offering simple recommendations for achieving healthier living space for horses starting with an existing barn.
For venting an existing barn roof, I suggest one of two options:
1) Add Dutch doors along the barn sides or
2) Add a vent along the bottom edge of the skylight (or ridge if that works best though I prefer the curb vent for better free air access).
Option 1: Add Dutch doors along the barn sides
This option provides good access for ventilation to each stall and a great method of controlling air flow. An owner has the option of leaving just the upper door open to reduce the flow or open both upper and lower doors to give maximum free area. (Of course, in order to open both doors for full access you’ll need to add an interior mesh panel to keep horse in the stall.) If Dutch doors aren’t possible or within the budget, then I recommend adding low wall vents to bring in air low to the floor (which is good for foals and to vent odors caused by ammonia gases near the floor). The vents should be dampered for air control and screened to keep rodents from getting into stalls.
Additionally, Dutch doors provide an abundance of natural light, which reduces the need for electric lighting in the barn and helps purify the stall flooring, reducing the creation of harmful ammonia gases.
Option 2: Add a vent along the bottom edge of the skylight (or ridge)
This option allows for vertical ventilation of the barn using the Bernoulli Principle and the chimney effect. Though the existing barn may not have the best angle for prevailing breezes or roof slope, it will help nevertheless. I also recommend vents at the top of the wall at the roof eave if they can be added. This permits year-round ventilation above the heads of the horses, but still ventilates the barn vertically using the techniques described above.
There are a variety of methods and materials that can be used to retrofit skylights into an existing roof. At Sagamore Farm, Blackburn Architects’ design replaced the existing shingles with a new metal roof (not necessary; Sagamore’s roof shingles were worn out and metal was chosen as a better long term material). In more typical circumstances where the existing shingles are salvageable, simply remove the shingles along the ridge and cut out the sheathing or sub roofing material, leaving only the roof rafters.
Continuous curbs should be built along the edge of the opening. Although a continuous skylight or curb is not necessary, I find it aesthetically and functionally preferable. A skylight can then be placed on top of the curbs spanning from one side of the aisle to the other. The curb can and should be vented. The size and amount of free area depends on the barn design, size and location. The skylight width does not have to span the full width of the aisle but somewhere between 8 to 12 feet should be adequate.
The skylight can be either glass (costly and should be safety glass) or some form of polycarbonate. Check your local building codes for requirements. I do not recommend clear glazing. Translucent glazing reduces the visibility of dirt and filters light, which better serves the barn interior. It’s best not to let a strong band of sunlight hit a stalled horse for a long period of time. I also recommend painting the interior of the roof and framing members a light color to improve reflectance.
If a continuous skylight is not possible, then individual roof skylights can be installed over the center aisle. However, if the skylights are not high on the roof and are not vented, they may not do much to increase the barn’s vertical ventilation.
If the barn has a loft it may be possible to remove it, leaving specific structural members spanning across the barn to hold the building together and to provide wind shear strength to the barn. If the loft is used for hay storage (which I don’t recommended for health and safety reasons), then it may be possible to remove a portion of the loft over the aisle leaving the loft in place over the stall for storage or the reverse of that (remove the loft over the stall but leave it in place over the aisle).
While these approaches to increasing light and ventilation in existing structures can work wonders, you should always contact a structural engineer before installation of skylights to determine if the barn can take the modifications needed of if some additional structural work needs to be done.
1. Blackburn designs stalls of all sizes, but the most common is 12’x12’. 16’x16’ is often requested for larger horses, but with more space comes increased maintenance, a need for more bedding and a bigger area to clean. Larger stalls can, therefore add considerably to the cost of building a barn by:
a. Adding to the overall length and/or width of a barn.
b. Requiring roof framing to be increased from 2×10’s to 2×12’s or even greater.
c. Increasing the span of the framing lumber.
2. Partitions between stalls should be at least 8 feet high, but they don’t have to be solid from top to bottom. Barred or mesh portions on the top enhance ventilation. This also has the benefit of allowing horses to see their companions — and provides easy observation of the horses by their owners. The down side is the increased ventilation between stalls can increase the risk of bacterial infection between horses. For the same reason, doors that are open on top increase light and ventilation. Bars must not be more than 2 to 3 inches apart, and openings should not be more than 2 inches across to prevent hoof entrapment.
3. Steel mesh or bar fronts on stalls allow an owner to look down the aisle or into the stall as they walk down the aisle and see their horses. The mesh is good for ventilation, too. The drawback is that bedding can be kicked into the aisles, so we recommend adding bedding guards. Welded steel mesh is typically stronger than bars but the horizontals tend to collect dust and can add to barn maintenance.
4. Doors should be at least 4 feet wide. This is wide enough for a wheelbarrow to enter the space or for a horse and handler to exit or enter the stall. Sliding doors are preferred over swinging doors. If you must use swinging doors, remember to install them to swing outward. You’ll have a major problem if a horse goes down and the door swings to the inside. Additional safety reasons for outward swinging doors include:
a. Prevention of an unlatched door swinging open accidentally, or the wind catching it.
b. Added visibility of looking down an aisle and recognizing that a stall is open and empty. (Handlers need to leave stall doors open when the horse is turned out. This also makes it easier when bringing the horse back to the stall – you don’t have to open it.)
5. We recommend rounded edges in stalls and anywhere in the barn where horses have access. A casting rail (which can be a groove in the wall or a 2-by-4-inch rail bolted low to the wall), provides something for the horse to catch his foot on when rolling to avoid getting cast.
6. Provide for easy access to the stall for feed buckets without opening and closing the door. Place in one of the front corners adjacent to the aisle.
7. Automatic waterers have the advantage of offering constant fresh water, but be sure to buy a model that is easy to keep clean. If you don’t want automatic waterers, install water hydrants between every couple of stalls and provide for ample drainage for drips and overflows. Don’t forget to frost-proof them in climates where pipes are apt to freeze.
On the 3rd of May, the day before the Kentucky Derby, I was sitting on a plane having just completed the final edits to my forthcoming book, Healthy Stables by Design, and reading the Time Magazine piece “Twilight at the Track” by David Von Drehle. I congratulate Time Magazine and Mr. Drehle for his article, as well as the numerous articles published by the NYT about horses and racing that I read frequently. I thought I would share a few of my thoughts about the things discussed.
Mr. Drehle’s article describes the sad situation of thoroughbred racing in the US. As tracks close, purses dwindle, breeding declines, and trainers and breeders retire, fewer and fewer people are attending, betting at, and enjoying the races. Surprisingly, the article states that only 46% of horse racing fans would even recommend the sport to others. Perhaps this fact should not be so shocking, as only a few races, such as the Kentucky Derby, Preakness Stakes, Belmont Stakes, and Breeder’s Cup, still manage to attract large numbers of excited spectators.
Having designed horse stables and planned many horse farms in my thirty-year career as an equestrian architect (some even for leading thoroughbred farms such as Sagamore Farm, Lanes End, and Heronwood Farm), this story does not actually tell me anything new. That’s not a criticism, as I think most people connected with thoroughbred racing in this country are aware of its sad decline. There are some passionate breeders out there with a desire to restore racing to its glory and to build on its history. Kevin Plank (Sagamore Farm) and Will Farish (Lane’s End) are two that embody the spirit and love of the sport.
Let me just say that I simply love horse racing. For me, it is the most fantastic sport in the world. With the parade to the paddock, the showing of the horses in the parade ring, and the procession to the starting gate, excitement builds with every step. Though one race is typically only two minutes long, those two minutes are definitely “the most thrilling two minutes in sports.” Since each race has various changing elements, such as length, track surface, and horse gender and age requirements, no race ever runs the same. By watching various races throughout the day, one can truly spend a great and full day at the track.
Having attended a number of races, I have my own methods that add to the excitement. Starting the day with a review of the racing form and the “pink sheet,” I begin to make my choices. This can be a long and tedious process or it can be a quick review of basic facts and data, like the jockey, horses’ record, trainer, and field. Mind you, I am certainly no expert at playing the horses and I never wager large sums, but betting definitely adds to the excitement and the thrill of victory. Once I have made my preliminary choices and stopped at the wagering window, I make my way to the top of the home stretch at the rail. This is my favorite spot to see a race because you cannot only see everything, but also feel, smell, and hear it. There is nothing like the excitement that floods your veins when a herd of horses rounds the turn into the homestretch galloping at top speed with leather rubbing, hooves pounding, dust flying (or at the Derby this year, mud flying), and the crowd cheering. While some may prefer the finish line or the expensive seats high up in the stands, I need to be where I can see, feel, smell, and hear it.
My experience with racing is based on this excitement and entertainment. Now the question is what can we do to bring this excitement back to the track and make the experience of going to the track enjoyable (whether one wins a little money or not)?
From my point of view, there are two main problem areas with racing. First, drugging and doping is still a sad negative pulling down the most exciting sport in the world. Not only does this severely endanger the horses, but it also detracts fans from the sport. Laws need to be restructured so that the punishment for drugging deters owners and trainers from the practice. Perhaps then, racing will truly be about the quality of the horses. Although strides have been made to remedy this problem, the restrictions have not yet solved the issue. Second, a change to the racing experience is necessary. The “racino” culture proposed as a “fix” to infuse money into an ailing industry is not a long-term benefit and may not be a “fix” at all for the sport. Though it may have helped by creating larger purses, improving competitiveness, and bringing bigger fields, it does not return the public back to the track. In fact, I believe it drives them away by cheapening the experience.
Perhaps with these two fixes, racing can begin to deliver everything that people used to love. One only has to attend Saratoga in August to understand the excitement that a full track can bring to thousands of diverse people and families, who gather to enjoy a full day of fun. It is this type of full-day experience, where families, couples, or individuals can go and hang out at the races, eat at good restaurants, and enjoy the spectacle of the day, that may restore racing to its former glory. I think some of the tracks in the UK might be a good example for our American tracks to consider. Having attended thoroughbred tracks in the UK (Windsor and Goodwood), I have seen first-hand how the experience can be thoroughly enjoyable. Though the British are known for betting on virtually anything that moves (and probably some that don’t), there were no tacky racinos, but rather, a pervading sense of pageantry and style. With this atmosphere, the racetrack became a place I could take my wife and enjoy a delightful afternoon.
In the US, Keeneland Racetrack, which only holds 32 days of racing each year, has reduced the amount of race days in order to have every race feature strong horses and large fields. Interestingly, their attendance and profits have rose amidst the closing of tracks across the country. By being able to restore the integrity of the sport, they have been able to make racing successful despite the declining industry. Let’s hope that other racetracks take note and restore the enjoyment of a day at the track. While the professional bettor or the individuals who hope to hit the perfect Trifecta may not be deterred, the future of Thoroughbred Racing lies in making it an experience that everyone can enjoy. By stopping the current drugging problems and the overall cheapening of the racetrack experience, I believe it can be done.

Much of the world seems to view horse racing through a different set of binoculars compared to the United States. Racing regulators in Kentucky recently approved a ban on furosemide (brand names Lasix or Salix), long considered a performance-enhancer in thoroughbreds (and thereby banned) throughout much of the world. The proposed phased-in ban, which would halt use of the drug in graded or listed stakes races, still needs approval from state lawmakers – and, as expected, the debate is controversial at best and downright ugly at worst.
Furosemide, the drug at the core of the debate, is a synthetic compound which functions as a powerful diuretic – it’s also the only medication currently allowed to be administered on any given race day in much of the U.S. The medication is used as an anti-bleeding drug to prevent race horses from nosebleeds during races and to treat pulmonary hemorrhaging.
One side of the argument is that a ban would create even more difficulties for an already struggling industry, as the business that gave Kentucky much of its fame has struggled to compete against states where the lure of larger purses is supported by legalized slot machines and the like. Others who are anti-ban suggest that the drug is a less cruel method to prevent or stop bleeding, as presented in “The Case for Using Lasix” in the New York Times.
On the other hand, some argue that banning the drug will boost public opinion of the sport, which has been marred by doping and injuries to both horses and the jockeys who ride them. In an editorial, “Stronger Medicine for What Ails Horse Racing,” the New York Times points out that “this is a good start, but regulators across the country will need to do a lot more to change the industry’s cynical culture, which turns a blind eye to drug use and imposes only wrist-slapping penalties on trainers caught in the act.” Another interesting viewpoint comes from the veterinarian Sid Gustafson, who says: “To allow racing veterinarians in a stall with a horse before a race is to permit doping, as it has turned out in America.”
The World Anti-Doping Agency (WADA) lists furosemide on its banned drug list due to its alleged anti-masking agencies.
Blackburn Architects is so grateful to be a part of Kevin Plank’s dream to revitalize the horse racing industry in Maryland through his work at Sagamore Farm in Glyndon. We hope you’ll enjoy these articles from The Washington Post and The New York Times about Mr. Plank’s impressive ambitions for the historic farm and to elevate Maryland’s racing industry clout. We believe that if anyone can do it, it’s Mr. Plank. Congratulations to the whole team at Sagamore Farm, whose All Mettle won Pimlico’s $30,000 maiden special weight race in only her second career start!
Originally on a 200-acre parcel of lush green rolling hills in Kentucky horse country between Layette and Bourbon Counties, Monticule Farm was named for the French word for a small mountain. Blackburn Architects worked with famed landscape architect Morgan Wheelock to develop the property, now over 600-acres, into one of the industry’s best commercial breeding facilities. Blackburn designed a 20-stall broodmare barn and a 16-stall yearling barn in the style of other large Kentucky horse farms from the 1940s. In 2008, Blackburn provided master plan and concept design services for a four barn stallion complex; each barn contains four stalls. This project was featured in Keeneland Magazine.
