A dark walnut staircase merges with a kitchen counter and a bathtub inside this renovated apartment in Mayfair, London, by architecture studio KHBT (+ slideshow).

The combined elements create a dark wood strip that stretches through the apartment from the kitchen at one end to the bathroom at the other, negotiating split levels by staggering up and down.

“The existing flat already had a stair running from one room to the other due to head height restrictions at the main public staircase,” KHBT partner Karsten Huneck told Dezeen. “The former design tried to hide this stair, but we saw it as the defining element of the flat which should be celebrated.”

“This approach led to the concept of creating one ribbon which runs even further than the stairs require, incorporating the kitchen block as well as the bathtub,” she added.

Describing the decision to use walnut, Huneck explained: “We wanted to create a precious element, using a timber that refers to the traditionally and luxuriously fitted flats in the surrounding area of Mayfair.”

The architects kept the layout of the apartment as it was, but cleaned up the spaces with white walls, floors and ceilings that contrast with the dark wooden strip.

KHBT have offices in both London and Berlin and recently completed a timber-clad house extension in Offenbach, Germany.

No 1 Balfour Place – Residential Development in Mayfair

A rundown flat in prestigious Mayfair has been transformed into an inhabitable sculpture.

Balfour Place by KHBT

Formerly there were 2 separate flats which have been connected with a space defining spine. Due to head height restrictions of the communal staircase running across this spine various steps and level changes had to be overcome.

This led to the main concept, a meandering ribbon which becomes an inherent part of all main functions of the flat: Kitchen, Stair, Circulation and Bathroom.

The ribbon runs through a glazed separation between corridor and bathroom, a screen that is made of electrochromic glass which can be changed to be an opaque screen.

Made out of precious massive walnut timber it creates a fitting character to typical flats in the area and at the same time a contrasting element to the white flooring.

Haus Bergé by KHBT

KHBT of London and Berlin has doubled the size a 1970s family house in Offenbach, Germany, by wrapping a timber-clad extension around the walls and over the roof (+ slideshow).

Named Haus Bergé, the family house was extended to create enough room for guests to stay.

The new structure climbs up on one side of the two-storey building and KHBT have also added an extra storey over the northern corner, altering the shape of the roof.

“The roof shape was developed through a continuation of the existing double monopitched roof,” architects Bernd Truempler and Karsten Huneck told Dezeen, explaining how they extended the surface in one direction before folding it around the chimney.

At ground level the grey brick walls are left exposed, while the upper floors are clad with wooden fins that have been painted in a weather-resistant mineral coating.

To carry the weight of the extension, the architects added additional supports to the house’s structure. “We had to punch through the existing first and ground floor in order to bear the new floor on its own structural elements,” explained Truempler and Huneck.

The staircase remains in its original position in the northern corner of the building but the architects have extended it upwards to connect the lower levels with the new top floor.

Other German houses we’ve featured on Dezeen include a red concrete residence outside Stuttgart and a house in Wiesbaden with a cinema on the roof.
