A comprehensive CAT A refurbishment of this Art Deco building on Oxford Street. Originally designed by Trehearne in the late 1920s, our client appointed us to re-interpret the reception area and common parts which, by way of late 20th Century insensitive interior design, had lost their design connection with the original architecture.

By reinterpreting the original Art Deco design we have created a new language that harks back to the intent of the original 1920s Trehearne design bringing back materials such as terrazzo, stone and bronze.

Our design for the rug in reception

Early concept watercolour

The office interiors have been pared back to expose the original beams and columns and a contemporary rafted ceiling system has been designed to maximise floor-to-ceiling headroom and increase daylighting levels within the accommodation.

New terraces and areas of green roof have been created on the set-back upper levels and at roof level a large proportion of the existing mechanical plant has been removed in order to create a generous communal terrace overlooking Oxford Street and Mayfair. New external balustrading to all terraces reinstate the original geometry of the balustrades within the building.

A new staircase was designed to contrast with the existing Art Deco terrazzo stair and beautiful curved balustrade.
