The Mozart House is a residential extension in Belgravia, London, designed by Studio Dera for a Grade II-listed Georgian property. The project replaces a former swimming pool with a new suite containing a bedroom, dressing room, and lounge, positioned within the garden of the existing house. The addition is connected to the main building through a colonnade that overlooks a series of terraces and sunken courtyards.
The structure is defined by a thin, floating roof plate supported by a single slender column, creating a lightweight enclosure with minimal visual obstruction. Glazing wraps the pavilion, allowing natural light to enter from multiple sides and extend into the lower levels. The design introduces new internal spaces while maintaining the original building’s layout and heritage constraints. The extension operates as a distinct volume within the garden
Sculptural Garden Extensions
Mozart House by Studio Dera Adds a Lightweight Pavilion to the Home
Trend Themes
-
Lightweight Floating Roofs — A thin, cantilevered roof aesthetic that emphasizes minimal visual mass while redefining domestic spatial demarcation, enabling radically lighter structural systems for additions.
-
Transparent Garden Pavilions — Glazed, freestanding volumes set within private gardens that blur indoor-outdoor boundaries and create new passive-lighting and programmable living zones.
-
Single-point Structural Supports — Slender, singular columns that concentrate loads to reduce footprint and open sightlines, prompting compact foundation and connection innovations.
Industry Implications
-
Residential Architecture — Conventional home design is being rethought through discrete, lightweight extensions that preserve original plans while enabling high-performance, low-impact additions.
-
Heritage Property Renovation — Conservation-led projects are integrating contemporary, reversible volumes within historic settings to reconcile preservation rules with modern spatial needs.
-
Prefabricated Building Systems — Factory-produced, modular glazing and roof assemblies are positioned to support rapid on-site installation of delicate pavilion forms and reduce disruption to existing sites.
