Cherry and steel curved staircase

dartmouth, DEVON

 

We were commissioned to design, make and install a bespoke staircase for a listed house in Dartmouth, which was part of a larger project designed by Stan Bolt Architects. The brief was to create a unique curved staircase at the top of the house to take you from the second floor up to the attic with no central support.

Mixing hot rolled laser cut steel, English cherry wood and custom fixings the stair has a beautiful combination of materials, which each play their part aesthetically and functionally to make the whole.

The structural requirements meant that the staircase needed to be ultra lightweight, yet extremely stiff and the spatial constraints of the building meant that we designed the stair in three segments to be small enough to fit through the existing house. The three segments bolt together with custom NAB (nickel, aluminium & bronze) fixings and form a monocoque structure. We worked closely with long time collaborators Define Engineers to achieve the structural goal, the result of which is a paper-thin curved steel stair, which is only 3mm thick!
