Sarek Roundhouse is a striking circular house built in the heart of the Cambridgeshire countryside.
The roof, which incorporates a glazed cupola, contains more than 500 linear metres of James Jones i-joists, which allow for high levels of insulation to a depth of 300mm.
Our i-joists team worked closely with the main contractor and engineering consultants on the project to help realise the architect’s designs.
