An equestrian steel building is a steel-framed structure designed specifically for horses rather than general storage, covering everything from a clear-span indoor arena to a stable block, an American barn, a field shelter, or the hay and feed stores a working yard needs alongside them. TC Rowan designs, fabricates and erects equestrian steel buildings from our own workshop on Thorpe Way Industrial Estate in Banbury, and because the same team draws, welds and bolts the building together, a yard planning an arena, stabling and storage can have the whole scheme handled by one contractor instead of three.
The buildings we frame
A working equestrian yard is rarely one building, so we design and build the full range, either as single projects or as one combined scheme.
- Indoor riding arenas. A clear-span steel portal frame carries the roof with no internal columns, so the riding surface stays open from wall to wall whatever the discipline. Covered in full on our indoor riding arenas page.
- Stable blocks and American barns. Individual stables in a row, or loose boxes arranged down a central covered aisle in a single building, both designed for ventilation, kick-resistant linings and safe daily handling. See our steel framed stables page for the detail.
- Field shelters. Simpler, open-fronted steel structures for turnout paddocks, built to stand up to an exposed field for years. Detailed on our steel field shelters page.
- Hay, feed and machinery stores. High-eaves, wide-opening steel buildings for stacked hay and straw, feed storage, and getting a tractor or trailer through without obstruction, part of our wider agricultural steel buildings work.
- Combined yard layouts. Many clients need an arena, a stable block and a store on the same site. Designing them together as one steel frame buildings scheme keeps access, drainage and the finished look consistent across the whole yard.
Standard arena and stable dimensions
There is no single correct size for an equestrian building; the right footprint depends on your discipline, your horses and what your land allows. The figures below are commonly used starting points, not fixed rules, and every job is sized to the actual brief.
| Building | Common sizes | What drives the steel |
|---|---|---|
| Short dressage arena | 20m x 40m | portal frame clear span sets column spacing and rafter depth for the full width |
| Full-size dressage or competition arena | 20m x 60m | the longer span needs deeper rafters and enough eaves height to keep the roof clear of a rider |
| Individual stable | around 3.6m x 3.6m (12ft x 12ft), larger for big horses or a foaling box | bay spacing along the stable block frame, plus door widths sized for safe handling |
| American barn | sized to the number of loose boxes plus a central aisle | overall building length and aisle width add on top of the loose-box run, so the frame spans wider than a single stable range |
Whatever the brief, the portal frame is what removes internal posts from the working area, which matters as much in a four-stable block as it does in a full-size arena.
Planning and permitted development for horses
Keeping horses for riding or leisure is not treated as agriculture for planning purposes, which is an important distinction on land that also has farm buildings. It means stables, indoor arenas and the buildings that go with them usually sit outside agricultural permitted development rights and need a planning application, even where a genuine farm building on the same holding might not. Rules differ by site, local authority and existing use, so we cannot give you a ruling; our planning permission for stables and a menage guide walks through the typical questions, and our agricultural building permitted development guide covers the farm-building side for comparison. Always confirm your own position with your local planning authority before you commit, and we design the frame to fit whatever scheme gets approved.
How a project runs with us
We run every equestrian project the same way, whether it is a single field shelter or a full yard, following the same design and build approach across every service we offer.
We start with a site survey, or work from plans you already have, and produce the design and fabrication drawings for your sign-off. Where the building needs it, that includes a structural engineer’s calculation and Building Control involvement before steel goes on order. Fabrication happens in our own Banbury workshop to BS EN 1090 execution standards, and our own team erects the frame on site rather than handing it to a subcontractor. Cladding and roofing are specified and fitted as part of the same project, working with trusted partners where a specialist finish is needed, and stable fit-out (linings, doors, tack and feed rooms) is agreed and built in alongside the frame. For a steer on what shapes the cost of a project like this, see our equestrian building cost guide and, for arenas specifically, our indoor riding arena cost guide.
A real example: Stow-on-the-Wold
In Stow-on-the-Wold, in the Cotswolds just over the Oxfordshire border, we delivered a complete new build of stables and a barn as a single-contractor project. We fabricated the portal frames for both buildings in Banbury, erected them on site, carried out the full envelope cladding, fitted windows for natural light, and installed automated doors for daily use. The client took handover of two finished, working buildings from one company, not a bare frame left for other trades to complete. It is the same approach we would apply to an arena and stable combination anywhere in our area, and it is worth reading alongside our barn conversion guide if an existing building is also part of your plans.
Where we work
From our Banbury base we cover Oxfordshire, the Cotswolds, Buckinghamshire, Berkshire, Northamptonshire and Warwickshire, with larger equestrian projects taken on UK-wide. We are used to working across county boundaries on rural and equestrian sites, as the Stow-on-the-Wold project shows, and we will travel further afield for the right project.
Why a steel frame for equestrian use
Horses are hard on a building over the years they use it, and steel handles that better than timber. A clear-span portal frame removes internal posts, so an arena stays open wall to wall and a stable block or American barn can be laid out however suits the yard. Steel goes up quickly once fabrication is complete, which shortens the time your horses are out of a finished facility, and it is durable: a galvanised or coated frame does not rot, warp or work loose the way timber does under years of knocks and damp. It is also easy to extend without redesigning the whole structure, and the low-maintenance finish saves time and money over the building’s working life. For background on how horses are cared for and stabled, the British Horse Society publishes independent welfare guidance worth reading alongside your own planning.
Frequently asked questions
What counts as an equestrian steel building?
An equestrian steel building is any steel-framed structure built for horses rather than general farm use: indoor riding arenas, stable blocks, American barns, field shelters, and the hay, feed and tack storage that goes alongside them. TC Rowan designs and fabricates each type in-house, so a yard with an arena, a stable block and a feed store can have all three built by one contractor as a single coordinated project rather than three separate jobs.
What size should an indoor arena or stable block be?
It depends on your discipline, your horses and your site, so we design around your brief rather than a fixed catalogue size. As a guide, 20m x 40m and 20m x 60m are commonly used dressage arena footprints, and individual UK stables are commonly built around 3.6m x 3.6m, larger for big horses or a foaling box. These are widely used starting points, not rules, and we size the actual clear span and eaves height to your land and your riding.
Do I need planning permission for an equestrian steel building?
In most cases, yes. Keeping horses for riding or leisure is not treated as agriculture for planning purposes, so stables, arenas and associated buildings usually fall outside agricultural permitted development rights and need a planning application. Rules vary by site and local authority, so we cannot give a ruling; always confirm your position with your local planning authority before you commit, and we design to whatever gets approved.
What is an American barn, and is it different from a stable block?
An American barn is one steel-framed building with a central aisle and stables arranged as loose boxes down either side, so horses, handling, tack and feed storage all sit under a single roof. A conventional stable block is usually a row of individual stables with doors opening onto the yard rather than an internal aisle. Both are steel-framed and built to the same standard; which suits you depends on your site, your headcount and how you want to work the yard day to day.
Which areas do you cover, and can you build the whole project?
From our Banbury workshop we cover Oxfordshire, the Cotswolds, Buckinghamshire, Berkshire, Northamptonshire and Warwickshire, with larger projects taken on UK-wide. We handle the whole job in-house: design, fabrication in Banbury, and erection by our own team, with cladding and equestrian fit-out coordinated as part of the same project.
