Raising horses takes a lot of work. It's imperative that you have the right supplies and a nice place for your horses to live. It makes sense to build a horse barn so that your horses have shelter, but there are several things that you need to take into consideration before horse barns construction begins.
One of the most important decisions you'll make before starting construction on your horse barn is where to put it. Ideally, your barn should sit close enough to your home that it's easy to access. After all, you might not always be up for a long walk when it's time to care for your horses. However, your barn needs to sit far enough away from your house that any sounds coming from the barn don't disturb you. Additionally, your barn needs to sit in a location that is close to existing electric lines and water supply — to make running the lines to the barn simple — and close enough to the road for trailers and maintenance workers to easily get to it.
When it comes to horse barns, bigger is often better. So, even if you're working within a budget, you should consider trying to build the biggest horse barn that you can afford. After all, it's easier to build a bigger barn from the start of the project than it is to add onto the barn later. If you're looking for ways to offset some of the cost associated with building a larger horse barn, consider using your barn to board horses for other people. Not only will this help you recoup the additional cost of building a larger barn, it'll help you cover some of the costs of maintaining your own horses in the long run.
A horse barn can't really have too many doors. It's the barn doors that will keep you from dragging large loads of supplies around the entire perimeter of the barn, so if you think you might need a door, build a door. If you discover at a later date that you don't actually use the door, just keep it closed.
Also, instead of placing windows along the barn's exterior, consider using doors. If you have a paddock right outside of your barn, you can leave the exterior doors open so that your horses can run freely. If you don't have a paddock attached to the barn, you can install dutch doors to keep the horses inside the barn, while still letting fresh air in — also, if you decide to create a paddock later, you'll already have your doors in place. Additionally, when you install doors at both ends of your horse stalls, it makes cleaning out the stalls a lot easier.
Ultimately, the size of your horse barn and its features are completely up to you. However, it's important to take the barn size, location, and features into consideration before you start construction. If you aren't sure of the best way to proceed with any part of your project, talk to your contractor.
