This large-scale office building is integrated into the historic urban context of London. Located behind the existing Daily Telegraph Building, the headquarters is a composition of smaller volumes which emerge as a group of harmonizing forms that summarize the existing context. Its grey granite walls are punctuated at the lower floors by tall glass window bays which recall the fenestration of neighboring structures, and feature recessed windows at the upper floors by square. Perimeter stair towers divide the north, east and west elevations. The south elevation is distinguished by a narrow tower and planes of glass and metal which acknowledge the Daily Telegraph Building. A vaulted stainless steel roof covers the tenth floor and combines with smaller roof top pavilions to create an animated and distinctive roofline.
The base is distinguished by black granite spandrels, brushed stainless steel panels and windows with mullions which match those of the upper floors. The pedestrian thoroughfare and immediate environment are enriched by the designís careful attention to surface treatment and detail, and to form and texture.
The project uses insulating glass throughout and employs a large curved reflective glass screen on the South elevation to throw light into the courtyard below. The reflective insulating glass also minimizes solar heat gain at the building's most valuable area.
The building has mechanical water-side "free cooling" changeover, allowing it to take advantage of the consistent temperate weather conditions of London, while significantly decreasing the overall operating costs. Ultraviolet radiation is utilized through a new type of water filter on all the cooling tower water systems, practically eliminating the risk of Legionnaires Disease recently found in many mechanical cooling systems of London office buildings. In addition, the on-floor air handling units have been extensively acoustically upgraded to eliminate any possibility of unwanted radiated or transmitted noise to the office space.
