AJ Specification case study: Superfusionlab has converted a north-west London industrial building into a light and airy residential development
The Lofts is a new residential development in north-west London occupying a converted 1950s industrial building. The building is brought back to life with large, warehouse-style windows and a new façade. The fabric of the building lent itself to larger openings to get light into the deep floor plate. The stair core is moved to the centre of the building, allowing it to be transformed into a residential building to house 28 apartments, a mixture of one, two and three-bedroom flats arranged over three floors. The fourth floor is set back from the building line with a sharp roof edge to complement the solid brick building. This level houses four penthouse flats, each with a private terrace, enjoying panoramic views.
The existing building’s large footprint meant that the deep floor plan needed careful consideration in order to take on the new residential occupation. Window sizes maximise daylight, while careful planning of the flats allows daylight deep into the interior.
The former light industrial use of the building dictated high ceilings which are maintained throughout with the new use, 3-4m ceiling heights were retained wherever possible. Open plan living is achieved with the kitchen being open to the dining/living light-filled area, a reminder of New York-style loft living. Brick surfaces are manipulated to enhance the ‘solid’ feel of the building, as well as to bring the façade indoors.

The selection of materials, fixtures and appliances for The Lofts’ kitchens and bathrooms followed a few simple rules. We selected materials and finishes that: complement each other;· create a seamless surface; give a level of ‘thickness’ to planar surfaces; and are easy to clean and maintain.
Kitchen counters and backsplash are Corian, forming a continuous surface that is easy to clean and has an elegant simplicity. Cabinet doors have hidden handles routed into the top edge and are sprayed blue-grey, RAL 7000. Fridges, freezers, extraction hoods and dishwashers are integrated. All appliances are Miele.
The bathrooms feature two different types of tiles. The en-suite bathroom has a 300 x 600mm cream porcelain tile and a 600 x 600mm floor tile of the same finish. The second bathroom features greenish-grey Grigio Egeo Matt complementing wall and floor tiles. Bathroom basins are Duravit Vero with a Crosswater Central Basin Monobloc tap;. The toilets are Duravit Happy D with a Grohe Air Button flush and the bathtub is a Bette Classic with Crosswater Central Thermostatic Valve and a Crosswater Wisp shower kit and bath filler. The towel rail is by Bauhaus Elite. All mirrors have an anti-fog mat and shaver socket is built into the cabinet. Shower trays are Matki Fineline.
