Building a Field Shelter for Horses on a Budget

Why a Shelter Is Worth the Effort

A horse turned out in a British field needs somewhere to escape the weather. In summer, that means shade from flies and strong sun; in winter, it means a dry, draught-free spot to stand out of driving rain and bitter wind. Commercial field shelters are excellent, but prices can easily run into several thousand pounds once delivery and groundwork are added. A well-planned DIY shelter built from reclaimed materials can do the same job for a fraction of that, and it can be tailored to your field rather than squeezed into whatever size the catalogue offers.

The key is to be honest about what you are building. A shelter is not a stable. It does not need to be airtight, insulated or beautiful. It needs to be strong, safe, dry underfoot and oriented correctly. Get those four things right and you will have horses that use it willingly, which is the only real measure of success.

Deciding on Size, Design and Orientation

For a single horse, a floor area of around 3.6m x 3.6m (roughly 12ft x 12ft) is a sensible minimum. Two horses sharing will want at least 3.6m x 7.2m, and if you have a dominant horse in the field, do not assume they will share politely. Many owners end up building two smaller shelters rather than one large one, and it is usually the better decision.

The classic design is a three-sided structure with a pitched roof and an open front. That open front should face away from the prevailing wind, which in most of the UK means the south-west. Point the opening towards the east or south-east and the horses get morning sun and shelter from the worst of the weather. If your field slopes, site the shelter on the highest practical ground so water runs away from it.

Before you commit, check a few practical points:

• Planning permission rules for your area — small agricultural buildings are often permitted, but size and siting matter.
• Whether you are on a livery yard with restrictions on what you can erect.
• Trees overhead, which drop debris and can cause rot and dangerous limbs in storms.
• Access for whatever vehicle will deliver your materials.

Sourcing Reclaimed Materials Sensibly

This is where the budget is genuinely won or lost. Reclaimed timber is cheap or free, but it must be sound. Never use timber that is soft, crumbly, or showing white rot. For posts buried in the ground, new pressure-treated timber is worth the money — it is one item where reclaimed stock rarely lasts.

Good sources to keep an eye on include farm sales, reclaimed building yards, local auction sites, and community noticeboards. Useful finds include:

• Corrugated metal roofing sheets — long-lasting, lightweight and often available from old agricultural buildings.
• Timber pallets and packing crates — excellent for cladding and kickboards once dismantled.
• Scaffold boards — hard-wearing and ideal for lower wall sections.
• Concrete blocks or bricks — handy for a hard-standing base or a plinth.

Buy new where it counts: structural posts, fixings, and roofing screws with rubber washers. Cheap fixings are false economy and a safety risk.

Preparing the Ground

Horses standing in mud defeats the purpose of a shelter, so spend a weekend on the base. Mark out the footprint and strip the topsoil. Dig post holes to at least 60cm deep, wider at the base than the top so concrete can lock the post in place. For a 3.6m x 3.6m shelter, you will typically be setting six posts — four corners and two flanking the open front.

Pour concrete around the posts and let it cure properly before hanging any weight on the frame. In the meantime, lay a base inside the footprint. Compacted hardcore topped with a layer of sand or a rubber mat is the simplest budget option. If you can stretch to it, a small concrete apron at the entrance stops the mud spreading and makes the shelter far more inviting.

The Build: Frame, Cladding and Roof

Frame the walls with 100mm x 50mm timber, using galvanised coach bolts or heavy-duty brackets at the joints. Add diagonal bracing to at least two walls — a rectangular frame without bracing will rack and loosen over time.

Clad the walls so that the bottom edge sits clear of the ground. A gap of around 25mm allows air to move and stops the timber wicking up moisture. Fix kickboards along the inside at roughly 1.2m high; scaffold boards are ideal. Above them, cheaper reclaimed boards are fine.

For the roof, a pitch of around 15 to 20 degrees sheds water well without wasting materials. Overhang the sheets by 150mm on all sides to keep rain off the walls. Fix corrugated sheets with the correct washered screws into purlins, never straight into thin cladding.

Finish by checking every surface a horse might rub against. Plane down rough edges, remove protruding nails, and cap the corners. If any treated timber is exposed, paint it with a horse-safe product, not a general-purpose wood preserver.

Keeping It Safe and Standing

Once built, walk round the shelter monthly. Look for loose fixings, splits in the timber, slipped roof sheets and any sign of rot around the post bases. Re-tighten bolts after the first winter, as timber shrinks and settles.

Keep the floor clean and topped up, and re-level the hard standing every year or two. A shelter that is maintained will comfortably outlast a cheap one that is not — and if you have built it well from reclaimed materials, you will know exactly how to repair it.
