Mozart House by Studio DERA
Mozart House reworks a Grade II listed house in the City of London, United Kingdom, by Studio DERA. The 2025 project turns a former swimming pool volume into two new floors of living space, using courtyards, daylight, and a measured material palette to answer a site shaped by heritage and a deep rear garden. Travertine, GRC panels, and timber linings give the interiors a steady rhythm.
About Mozart House
Nestled behind a Georgian terrace in Belgravia, Mozart House by Studio DERA creates two new floors of light-filled living space. The project converts a former swimming pool into a master suite, dining area, bathrooms, and a sunken courtyard.
The house is a Grade II listed building in the Belgravia Conservation Area, where Mozart once composed his first symphony and where Vita Sackville-West and Harold Nicolson later lived. That history shapes a careful intervention that respects the original frontage while opening the rear of the site to a new sequence of rooms.
An episodic route ties the extension together. Lower and upper courtyards connect through a refined colonnade, and the deep rear garden becomes part of the interior experience as views shift between planting and sky.
Material choices anchor the scheme. Travertine stone sits alongside GRC concrete panels, while soft timber linings warm the rooms and bifold openings, skylights, and courtyard windows pull natural light deeper inside. A lime-textured render art piece by Guy Valentine gives the sculptural lightwell another surface for daylight to pick out over the course of the day.
Planting softens the edges of the architecture. Layered greenery, potted trees, and a roof garden temper the hard lines of the extension, and overhanging planting falls toward the sunken courtyard, drawing the interior back toward the landscape.
