The existing house was part of a deceased estate and in an extremely dilapidated condition. Despite being located in a heritage conservation area, alterations and additions that were unsympathetic to the style of the house had been carried out to it over the years. These changes and the state of disrepair meant the house was unlivable.

The proposed design therefore looked to repair and reinstate the period features in the existing front half of the house. The uncharacteristic and almost windowless lean-to addition at the rear was demolished, and replaced with a modern, open-plan living space spilling out to the rear garden. An arched glass door in the ground floor corridor acts as the transition between old and new. A raked skillion roof to the living room further lifts the space with a generosity of height and daylight.

Upstairs, a new first floor addition with master bedroom, ensuite and balcony provides a much-needed parents’ retreat for the young couple and their growing family. It again reads as a modern design where it faces the rear but has been designed to blend in with the existing tiled roof at the front, to provide a respectful addition to the streetscape of the conservation area.

Contemporary materials and details have been used in the new parts of the house, with polished concrete floors, a suspended staircase and formed bath tub just some of the many bespoke elements that add a modern twist to the design.
