What is SFS
Steel Framing Solutions
A steel framing system builds walls, floors and roofs from light-gauge galvanised steel sections instead of timber or blockwork. The sections are made to measure off-site from the drawings, then fixed together on site into a frame that is insulated, boarded and finished like any other building.
Because the frame is light, it adds little load to the walls and foundations below — which is why it suits loft conversions and upper-floor extensions — and because it arrives ready to fit, it goes up quickly and accurately.
Steel doesn't shrink or rot, and at the end of its life it is fully recyclable.
- Lightweight yet incredibly strong
- Precision-built off-site for accuracy
- Faster assembly than traditional methods
- Fully recyclable materials
Applications & benefits
What Steel Framing Is Ideal For
Steel framing fits wherever a light, strong structure is needed — in the roof, at the back of the house or across a whole building.
Loft Conversions
A light frame for dormers and new roof structures that adds little weight to the house below.
Extensions
Single and upper-floor extensions with a quick, accurate structure that ties into your house.
New Builds
Houses and small developments framed in steel, then clad and finished to your design.
Commercial Units
Frames and infill walls for commercial units, offices and mixed-use buildings.
How we deliver
Drawn, Engineered and Built by One Team
A steel frame is only as good as the drawings it is made from. Our in-house architects prepare the design and the structural drawings and calculations, and manage planning and Building Regulations approval, so the frame can be made to measure before it reaches site.
Our own trades then assemble the frame, insulate and board it, and carry the job through to the finishes, with a project manager as your single point of contact. Every project starts with a free consultation and a fixed-price quote, and the structure carries our workmanship guarantee.

SFS stands for steel framing system. Walls, floors and roofs are built from light-gauge galvanised steel sections that are made to measure off-site, fixed together on site, then insulated, boarded and finished like any other building.
A steel frame is lightweight yet strong, so it adds little load to the house below, and because it arrives made to measure it goes up quickly and accurately. At the free survey our architects will confirm whether it suits your property.
No. Once the frame is up it is insulated and boarded inside, and the outside can be finished in brick, render or cladding to match your house and satisfy the planners.
Yes. As well as lofts, extensions and new builds, we use steel framing for commercial units. Larger commercial schemes are covered by our commercial new builds service.
SFS projects are priced on application, because the cost depends on the size and design of the structure. We start with a free consultation and give you a fixed-price quote before any work begins.
