This project turns a bland, boxy, much extended 1960’s dormer bungalow into a stunning, thermally-efficient modern family house by subtly reorganising the interior and complete over cladding with timber-based panels, zinc long strip and new composite aluminium windows and doors. The principal idea moves the stair to the front and the entrance below the central dormer, creating a double height galleried hall around which the principal rooms and bedrooms revolve. The irregular mis-matched dormers are unified with highly insulated metal cladding; which projects forward off the general timber cladding. To the rear a strip of sliding/folding doors opens the interior to the large garden via an extended terrace. We produced photo-real images of the exterior and interior from our single Building Information Model to allow the client to fully understand the proposals, drawing fully on our interior design experience to create a crisp modern design that integrates exterior and interior.
