Slim recessed handrails in the wooden walls of the stairwell are illuminated with yellow lights. Glazed doors added to each floor have treated steel frames that tone with the original window fittings and columns. The communal flight that connects all the floors is completely enclosed in a zigzagging form, with the other surfaces following the line created by the treads. The architects peeled back the layers of plasterboard, carpet and suspended ceilings to expose original wooden flooring, brickwork and iron columns across the first and second floors of the building. Exposed brick walls, rugged wooden ceiling beams and chunky wooden staircases with zigzagging undersides feature inside this office block in London, recently renovated by Amin Taha Architects (+ slideshow). Toilets are encased in large cubes constructed in the same oak used for the staircases. “We revealed the original robust structure that used only three elements – brick, iron and timber – allowing these to express the architecture.”
Two new oak staircases were inserted – the first to connect all of the floors, and the second to form an additional connection between the first and second levels, which could be rented as a single unit but are currently still separate. This is the first phase in a series of renovations being made to the building, which will later include the refurbishment of the ground and basement levels and a rooftop extension, once existing tenants have vacated.
