The quality of the project is testimony to a genuine collaboration between architect and client, giving a new lease of life to a much loved home that respects and enhances its sense of place.

Project description

For their North London townhouse, the clients approached us to design a double-height extension and remodel the interior to open up the lower and upper ground floor levels. The original configuration of the property meant that the garden was not accessible from the lower ground floor, so a primary facet of the brief was to ensure the outside space could be enjoyed from all of the lower levels of the property.

Entering on the upper ground floor at kitchen level, the interior spaces have been opened up to flow through into the new extension which, at this level, houses the new family kitchen/dining area with a dropped ceiling and circular roof lights. Beyond the kitchen island, a large dining area looks out through large glazed panels onto a new balcony overlooking the greenery of the rear garden. This is a beautiful, light-filled space with distinctive detailing and bespoke joinery that feels tactile and warm, yet bright and spacious.

The lower ground floor has been transformed into a flexible space for the family to pursue hobbies such as painting, with sliding partitions to allow the zone to be turned into guest accommodation. An existing utility room has been retained and enveloped in bespoke timber joinery—creating a unique feature-wall.

Outside, the rear elevation has been built using Portland stone which wraps up and around the entire structure, connecting the upper and lower ground floors. A staircase with a frameless glazed railing brings access from the upper ground floor balcony to the garden.

With the client being an architect, the project progressed with a natural sense of collaboration and sharing of expertise.

Material design

Portland Stone has been chosen for its crisp, clean edges and bright appearance. The stone is a substantial presence, with the entire extension clad to appear as though formed of one solid stone box.
