House at Cranham


The engineering design for this property was crafted to suit the requirements of the client in terms of the energy efficiency of the building.

It is a stick built timber frame but uses the “balloon” construction methodology more usually seen in North America. The external walls comprise two timber skins set 300mm apart to allow for very large levels of insulation. Manufactured I joists were used as roof cassettes again to permit increased depths of insulation to be specified. The property is open plan internally and utilizes ply web beams within the roof voids to provided additional support to floor beams (via hangers) in some areas to limit downstands.

Foundation and sub-structure design works were also included in our brief. These included a basement with reinforced blockwork retaining structures.
