Steel framed glazing creates botanical garden inspired extension.

A refurbishment and extension project in London featuring bespoke green steel-framed glazing

When the homeowners sought to expand their useable space and extend their home, architects Sinclair Studios were brought on board to bring the vision to life. The brief was to increase the space within the home whilst retaining the original charm of the London architecture with timeless steel framed glazing. 

The ground floor was extended into the garden and to the side of the property, utilising a structural glass roof to create a side infill extension. The direct access to the garden creates a strong bond between the inside and outside environments, which is only enhanced by the steel frame finish, muted green tone (RAL 7009).

Slim framed steel glazing systems were chosen for this London rear extension to achieve a more traditional look with the glazing, whilst creating a thermally insulated environment thanks to the thermally broken profiles. Steel windows and doors were specified with bespoke glazing bar designs and a steel panel at the bottom of the doors for a unique design.

The double steel doors have fixed sidelights on either side of the casement openings and a flush threshold for seamless travel between the new kitchen space and the garden patio. Every detail has been considered, including the hinges which are powder coated in the same matt green colour.

Beside the door, the side infill part of the rear extension uses both fixed and opening elements to flood the interior design with natural light and provide additional ventilation when required. The outward opening window sits underneath a triangular fixed window, which is linked to a glass roof.

The glass roof uses panes of structural glass and slim steel sections to create both horizontal roof glazing and vertical windows to maximise the light throughout the day. The green colour palette contrasts the surrounding traditional brick, whilst creating a theme throughout both the interior and exterior design. Biophilic design elements can be seen through the use of large living plants and green accents in the kitchen design.


The result is a well-designed, naturally lit open plan living space. The rear extension of this London home combines modern and traditional elements to create an indoor-outdoor style of living, whilst maintaining the original architecture to the front elevation and from the street view.
