PLP Architecture has designed a new office building that will sit adjacent to the Grade II listed Holborn Viaduct, marking a gateway to the Cultural Mile and significantly enhancing the public realm and pedestrian connectivity. The architectural language is a response to the building's context and is shaped to enhance the setting of the listed south-eastern gatehouse – one of four that frame the Holborn Viaduct bridge. Portland Stone, reused from the existing buildings, will form a new masonry base on Farringdon Street and weave the gatehouse back into the streetscape.
