TateHindle has refurbished and reclad an office building on New Oxford Street for developer Artillery Properties, cutting energy usage by 40 per cent, despite adding an extra floor.
Built in the early 1980s, 70 New Oxford Street occupies a prominent corner on the street, close to Centre Point and the new Tottenham Court Road Crossrail station.
Unattractive dark-brown brick cladding has been replaced with high performance glass with improved U-values to reduce thermal heat loss. A vertically-banded white dot fritted pattern has been applied to the surface in a subtle play of clear and semi transparency. The increased window area maximises daylight in the office areas, reducing the need for artificial lighting.
James Hindle, director of TateHindle, explained that the practice wanted to be sensitive to the adjacent conservation area, while adding a modern external appearance and internal office environment.
“The existing streetscape rhythm is created by strong vertical architectural elements on existing buildings nearby and this was reflected in the design of the new fritted glass façade.”
As a result of new energy-efficiency features, the building no longer required the large rooftop plant room. This created scope for a new top-floor, which increases office space by over 40% and brings the total floorspace to approximately 2700sq m.
“As buildings reach the end of their 25-year, or even 50-year lease cycles, the opportunity is presented to completely upgrade the external fabric and internal environment to create a building with a new image and energy efficient performance,” said Hindle.
