Kensington

This project at 48 Edwardes Square involved the creation of a contemporary glass box extension to the rear of the property. Designed by Richard James Hastings Architecture and delivered by NTJ London, the scheme focused on maximising natural light and strengthening the connection between the internal living space and the garden.

The extension was conceived as a clean, minimal intervention that complemented the existing house while introducing a more open and transparent rear elevation.

The extension was formed using a combination of frameless structural glazing and minimal aluminium framing. A full-height structural glass panel to one side created uninterrupted views.

Above, a frameless glass roof allowed daylight to penetrate deep into the space, improving the overall quality of light within the interior. The junction between the vertical glazing and roof glazing was carefully detailed to maintain a continuous, clean appearance.

The structure supporting the glazing was concealed where possible, with steel elements integrated into the build-up to ensure the required structural performance without impacting the visual simplicity of the design.

The main opening to the garden was provided by a 3m high aluminium framed pivot door. This sat within the elevation and provided a clear and functional access point between inside and outside.

The pivot configuration allowed for a wider and more balanced opening compared to a traditional hinged door, while maintaining a strong, simple visual presence. The frame was finished in a dark tone, helping to reduce its visual impact against the glazing.

When closed, the door maintained visual continuity with the surrounding glass. When open, it created a generous opening that improved circulation and enhanced the connection to the garden.

The glazing specification included low-emissivity coatings to improve thermal performance while maintaining high levels of clarity and light transmission. This helped ensure that the space remained comfortable throughout the year.

All elements were designed and engineered to meet structural and performance requirements, including allowances for movement, loading, and environmental conditions.

The completed extension provided a bright, open space that significantly improved the relationship between the house and the garden.

By combining structural glazing with a well-proportioned pivot door, the design achieved a balance between performance, practicality, and aesthetics. The result was a contemporary extension that enhanced both the functionality and spatial quality of the home.
