The 15-storey office building incorporates an innovative rotating stepped form in direct response to the challenging triangular plot on which it is set. Bounded by Fetter Lane and New Fetter Lane in London’s Midtown district, the building’s slender vertical ‘hinge’ defines the meeting point of these two streets.
A cascade of double storey stepped terraces resolves the scale change between west and east elevations. Rotating around the southern vertical hinge, the hinge itself is expressed by a translucent glazed staircase which filters natural light during the day and glows as a vertical white beacon at night, making the building a distinct landmark when viewed from the south.
Design director, John Silver of Doone Silver Architects says of the project, “The stepped form, rotating through the triangular site around a slender stair tower, provides a dynamic response to the building’s urban context and unlocks highly versatile open floorplates.”
The external envelope of the building is composed almost entirely of glass, while the core is clad in pale grey opaque glass vertical panels. The principal clear glazing to the offices is expressed as a multi-faceted and reticulated surface, with these diamond-cut facades generating complex reflections that change the appearance of the building throughout the day.
