Redevelopment of an existing 1970s office, which has been reclad with a high-performance glazed curtain wall for residential use.

Eckersley O’Callaghan has engineered the facade for the redevelopment of an 11-storey 1970s tower in London’s Archway, transforming the structure from office to residential units as part of a wider regeneration scheme. The existing ribbon window facade was removed and replaced with a new glazed curtain wall featuring floor-to-ceiling high performance glazing for the windows.

The tower has operable glazed panels and vents behind perforated aluminium screens provide natural ventilation to avoid overheating in summer. The new facade is designed as a unitised system to ensure quality fabrication and speed of erection on site.

The building has also been extended by two further floors constructed above the existing concrete frame. These floors are required to achieve higher performance standards than the replacement facades below, so triple glazing and winter gardens were proposed.

A particular challenge was the design of the supporting brackets to accommodate the large tolerances of the existing construction. This has required close collaboration with industry to develop custom bracket designs.
