Dalston House

Award Winning Glass Extension in London

This glazed rear extension garnered the attention of the architectural community and has won various accolades and awards, including the Sunday Times House of the Year Award.


Designed by HUT Architecture the extension and renovation works to Dalston House included the addition of a brand new highly glazed extension to the rear. The two “slick black boxes” to the back of the house were a key element of the architectural design.

The expansive use of glass within the structures draw in natural light to the rear living spaces and new staircase which leads down to an open plan basement.

large structural glass roof was designed by IQ to create a window to the sky for the larger and longer of the two glazed boxes. In keeping with the black metallic design theme, a slender steel section was used to support the frameless glass roof which spans over 4m in length.

At the rear elevation, the structural glass roof meets a set of sliding minimal windows which form the patio access doors to the extension. With sightlines of only 21mm and a flush threshold detail, the minimal windows sliding doors were perfect for this installation, making the most of the small aperture available within the glazed extension.

Further light is brought into the extension with the inclusion of a frameless structural glass ‘letterbox’ window to the side of the extension.

The taller of the two glazed extensions provides a double height elevation of glass to the new staircase area. An aluminium casement door opening was designed with a large fixed window overhead.

The structural glass window is completely frameless, adding an exciting element of modern design to a simple stairway area. All external surfaces of the glazed extensions were finishes with an expert matte black aluminium pressings that contrast beautifully with the clear glass faces.

The aluminium framing to the sliding doors and aluminium casement door were powder coated RAL 9005 Black to match the external cladding.
