What is COR-TEN?

Weathering steel (best-known under the trademark COR-TEN steel) is a group of steel alloys which were developed to eliminate the need for painting and form a stable, rust-like appearance if exposed to the weather for several years, resulting in a low maintenance, beautiful matt bronze appearance.


Each structure reacts to its environment differently meaning every project is unique as well as strong, long-lasting and environmentally friendly. Because of it’s distinct look and versaltility COR-TEN is a becoming a popular choice for many architecture designs as well as garden structures, projects and housing.

In our projects steelwork is adopted as the primary structural material, with weathering steel as the external finish.

See some examples of our work below. 


Lodge Farm, Kersey

luxury, modern home featuring a COR-TEN steel module. The striking COR-TEN colours compliment the cedar cladding and stone walls beautifully.


Snape Maltings Dove Studio

 This COR-TEN  steel art studio was built   within the ruins of a nineteenth century dovecote. The new dovecote studio sits inside the victorian structure as a COR-TEN steel ‘lining’, a welded structure that was built next to the ruin and craned in once complete. The building is fully welded in a single piece, like the hull of a ship, to achieve weather tightness. The finished result is an eyecatching structure against the beautiful landscape. 

Chartfield Avenue Putney

A This project involved redevelopment of a garage building in South West London. The high spec private house is set over four floors including a single basement. The rust-like appearance of the weathering steel cladding is a striking feature of the cutting-edge design of this private dwelling.


Weathering steel is also becoming a popular choice for smaller gardening projects including boardering, fencing, plant pots, bespoke furniture, bridges, summer houses, sheds and much more. It can be combined with a range of materials to create a unique feature and compliment any outdoor space with the added benefits of being low maintance and environmentally friendly.
