Extension to a semi-detached house built in the early 1900s

The brief was to extend the semi-detached house in a contemporary style. The semi-detached house built in the early 1900s provides a simple white rendered back drop to the design.

It was deemed that although the ground floor provided ample space, the two small bedrooms upstairs lack the same impact.

Not wishing to lose off-road parking the design solution was a cantilevered timber box extension which would replan the existing oversized bathroom and accommodate a new master-bedroom and ensuite. Re-configuring the ground floor would maximise space and natural light.

The property based in Winchester and over-looking the South Downs National Park meant the design had to make use of fantastic first floor views. The modern exterior featured a cantilevered timber box, clad in English Chestnut, which wraps around to the rear and balances delicately over a masonry element. The two interact but are off set to create a mixture of inside, outside and canopy spaces.
