Hill House Archway

Hill House is a former 1970s, 13-storey office building, which is part of the Archway Island site in Islington, north London. The proposal is to retain the existing building and convert 12 floors to residential use, housing over 150 flats and recreational facilities.

The redevelopment will involve complete internal refurbishment, re-cladding of the existing façade and general improvements to the immediate streetscape.

The scope of work proposed by Skelly & Couch will provide energy-efficient new building services; enhance the building façade to provide thermal control; and offer natural ventilation rates catering for both overheating (to comply with Islington design guidance) and fresh air. The residential block is estimated to provide 37% less gas consumption and almost 70% less electricity than its previous office use, leading to an overall carbon reduction saving of 72%, or 916 tonnes CO2 for the entire scheme.

Ventilation. The façade is configured to allow background and boost natural ventilation plus heat recovery connections.

Sunlight / Daylight. Specific solar control glass is being used to maximise the amount of available daylight whilst limiting the effects of overheating by direct sunlight.

Views. High proportion of glazing maximises opportunities for spectacular views of the London skyline.

Efficient serving. CHP and other efficient serving techniques are being used to comply with the strigent energy targets set by Islington Council.
