Steel frame
An innovative breed of precision-engineered, light gauge galvanised steel frame systems has sprung up in recent years, with plenty to offer self builders. What’s more, steel is a recyclable material and the frame can be insulated with the material of your choice – including natural materials – for an even more sustainable build.
The benefits
Robust and durable structure that ensures a long-lasting home
The frame is manufactured offsite, so time on site is minimised. Some suppliers offer modular builds for an even quicker route to weathertight
Enables wow factor design features such as vaulted ceilings and open-plan layouts
Galvanised steel is highly corrosion-resistant
The limitations
The designer must take care to fully wrap the frame in insulation to avoid thermal bridging
Work should be overseen and undertaken by experts As it requires specialist knowledge, labour and frame manufacture costs can be higher than standard builds
