Redevelopment and conversion of an existing 1970s office into residential use, and recladding with a high-performance glazed curtain wall


Hawkins Brown


Eckersley O’Callaghan is engaged as facade engineer on the redevelopment of a 1970s tower in London’s Archway as part of a wider regeneration scheme. The existing ribbon window facade is to be removed and replaced with a new glazed curtain wall featuring floor-to-ceiling high performance glazing.


Planning consent was granted in November 2014 and construction began in late 2015.


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


The building will also be 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 are proposed. Operable glazed panels and vents behind perforated aluminium screens provide natural ventilation and avoid overheating in summer. The new facade is designed as a unitised system to ensure quality fabrication and speed of erection on site.
