Delvendahl Martin converts Oxford semi into single house

  • Comment

Delvendahl Martin Architects has recently completed this conversion of two semi-detached houses into a single family home

The six-bedroom scheme in central Oxford joined two existing Victorian houses together with a new central staircase.

The party wall has been partially removed at ground floor level to create a large open plan living space.

While at the lower ground floor level two bedrooms are entered off a living space which opens out onto the garden.


The architect’s view

Two existing Victorian houses are joined together by introducing a new staircase at the centre of the plan and perpendicular to the party wall. The existing symmetrical arrangement gets thus rotated to achieve a continuous flow of spaces throughout each floor. The change of level from the entrance to the back garden is negotiated by introducing a second staircase and a new loggia accessible from the kitchen and main living room of the house. Planning permission was granted in September 2013 and the project completed in July 2015.
