We 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.”

“When you take a horse out of its comfort zone—the wild—it’s your obligation to create an environment that protects its health and safety. A poorly designed barn can be worse than no barn at all.” – John Blackburn
John Blackburn knows barns. As Blackburn’s owner and senior principal for the past 25 years, John has designed over 150 equestrian facilities across the United States and abroad.
In his blog, Stable Minded, John rhapsodizes about the design process behind our horse barns and equine facilities as only he can. His blogs cover a variety of equestrian news and topics: from the story behind projects we’ve designed to equestrian and design issues, such as how to increase natural lighting in barns. For those of you with questions or comments about the nitty-gritty details we face when designing barns, John considers his blog an open forum to discuss what’s on your mind.
If you’re curious about the architectural process, like to view construction photos from start to finish, or have questions about how it all works, we invite you to read and comment at Stable Minded. It might not be literally straight from the horse’s mouth, but we like to think it’s pretty close.
