An agricultural steel building from TC Rowan is designed, fabricated and erected by one Banbury contractor, from the portal frame up to the finished cladding. We build steel-framed barns, livestock buildings, hay and machinery stores, grain stores and general-purpose agricultural sheds for farms, landowners and rural estates across Oxfordshire and the neighbouring counties. Every frame is sized for the real loads a working building carries: snow, wind exposure, stacked bales, grain and the weight of machinery moving through wide door openings.
Agricultural buildings we fabricate
We work from a bare field or an existing yard, and the steel suits whatever the building has to do:
- Steel-frame barns: clear-span portal frames for storage, mixed farm use and shelter, with no internal columns getting in the way of machinery
- Livestock buildings: cattle and sheep housing designed around ventilation at animal level, durable internal linings and the muck-out and feeding access farmers actually use
- Hay and machinery stores: high-eaves frames with wide openings, built to take stacked bales and tractors, trailers and combines under cover
- Grain stores: heavy-duty frames specified for the loads and the airflow a grain store needs
- General-purpose agricultural sheds: flexible covered space for whatever the farm throws at it, from workshops to fodder and equipment
- Equestrian buildings: stables and arenas built to the same standard, covered in depth on our steel framed stables and indoor riding arenas pages
Steel portal frames for agricultural use
Most agricultural buildings are built as steel portal frames, and for good reason. A portal frame is a pair of columns joined to rafters at rigid connections, repeated in bays along the length of the building. That geometry carries the roof and wall loads down to the foundations without any internal supports, which is exactly what a farm needs: a wide, unobstructed clear span that a tractor and trailer can drive straight through, and full use of the floor for stock, storage or handling.
We fabricate the frames in our Banbury workshop to BS EN 1090 execution standards, then erect them on site with our own team and lifting plant. Because the same company draws, cuts, welds and erects the steel, the frame that turns up is the frame the building needs, with none of the gaps where farm projects usually slip.
One contractor, groundworks to cladding
We deliver agricultural buildings as a turnkey design and build package, not just a bare frame for other trades to finish. That means one accountable contractor coordinating the steel, the cladding and the openings rather than several trades pointing at each other when something does not line up.
We proved this on a complete new build of stables and a barn at Stow-on-the-Wold in the Cotswolds: structural steelwork, full exterior cladding, window installation and automated doors, handed over as finished, working buildings. Cladding packages, whether fibre cement, box profile or composite panel, are matched to the job, so a livestock building, a hay store and a workshop are each clad for what goes on inside. You can see more of our rural and farm work across the projects gallery.
Built to last in rural settings
A farm building has to stand up to weather, livestock and hard daily use for decades, so the protection on the steel matters as much as the frame itself. We galvanise or coat the steelwork to suit an exposed rural environment, because the difference between a building that needs constant attention and one that quietly does its job for years is usually down to how the steel was finished on day one.
The result is a low-maintenance structure: a galvanised or coated steel frame does not rot, warp or shrink the way timber can, and it shrugs off the damp, the muck and the knocks of a working yard. Steel also gives the long clear spans agricultural buildings depend on, which is the same structural advantage we put to work on the residential steel-frame house we manufactured and installed at Britwell Salome in Oxfordshire: open layouts and wide spans with no intermediate walls.
A note on planning
Agricultural buildings sometimes fall under permitted development rights, which can allow certain farm structures to go up without a full planning application. The rules depend on the size of the building, the holding, the site and how the building will be used, and they change. We are steel fabricators, not planning consultants, so treat this as general background rather than advice: always check the position with your local planning authority before you commit. What we can do is fix the frame geometry early, so the building you take to your local authority is the building we put up, with no costly redesign once the steel is on order. For a steer on the numbers behind an equestrian build specifically, our equestrian building cost guide breaks down the factors.
Frequently asked questions
Do agricultural steel buildings need planning permission?
Sometimes, and sometimes not. Some farm buildings fall under agricultural permitted development rights, which can allow them to be built without a full planning application, while others need consent. It depends on the size, the holding and the intended use, and the rules can change, so always confirm the position with your local planning authority before you start. We are happy to fix the frame design early so what you submit matches what gets built.
How long does a steel barn take to build?
It depends on the size of the building, the groundworks and the cladding specification, so we give a realistic programme once we have surveyed your site and agreed the design, rather than quoting a figure that does not fit your job. As a rule, the steel frame itself goes up quickly once foundations are ready; the wider programme is shaped by groundworks, the cladding package and access on site.
Can you build the whole building, not just the frame?
Yes. We deliver agricultural buildings as a complete design and build package, from the structural steelwork through to exterior cladding, windows and doors, with one contractor accountable for the finished building. The Stow-on-the-Wold stables and barn build is an example of that full scope.
What areas do you cover for agricultural buildings?
We design, fabricate and erect agricultural steel buildings from our Banbury workshop across Oxfordshire and the surrounding counties, including Buckinghamshire, Northamptonshire, Warwickshire and Berkshire. Get in touch with the site location and what you want to build, and we will arrange a survey.
