GIRDLESTONE HOUSE

Rooftop Extension, Oxford

Girdlestone House involves the delivery of a two-storey rooftop extension above an existing three-storey residential building, creating eight additional apartments while retaining the nine existing homes below. Lynrace Studio led the redesign and planning process, developing an evolved scheme that builds on an earlier consented proposal to improve unit mix, circulation, and the architectural integration of the new upper floors within the surrounding context. The project includes significant upgrades to the existing building, including the introduction of a passenger lift, a fire-protected stair core, replacement glazing, and improved cycle and refuse storage, bringing the building fully in line with current Building Regulations. Careful consideration was given to daylight, privacy, massing, and the mature trees surrounding the site, ensuring minimal impact on neighbouring properties. The scheme is currently on site, with completion scheduled for Summer 2026.
