Refurbishment of and addition to a 1980s concrete-framed office building, providing open plan office space. Inner courtyard has been sealed and transformed into a main atrium
Angel Building is the re-invention of an early 1980s commercial building located on one of London’s historic focal points where City Road and St. John Street meet Pentonville Road.
The existing concrete frame is re-used and re-wrapped with a highly energy-efficient glazed skin, which extends the building’s envelope at selective points to create a better fit with the surrounding context.
An extra floor is added to the building, in all creating an additional 9,200m2 of floor space.
An existing open courtyard is enclosed to form an internal, top-lit public room entered off St. John Street, which acts as the entrance area, improves circulation and offers breakout spaces.
