Formerly a glue factory on a quiet Clerkenwell street, 20 Garrett Street now provides 18,000sqft of CAT A office space. This retrofit project is a celebration of historic features and materials to enhance occupant wellbeing. Existing parquet floors, glazed bricks and steel structure are all exposed and restored to minimise embodied carbon and building waste through construction. Crittal windows are retained, which in combination with a shallow plan allows internal spaces to be day-lit and naturally ventilated. Additional lighting is supplied by a series of different energy-efficient circular luminaires using occupant movement sensor technology to minimise energy usage. This organic arrangement allows for a more human occupation of the spaces than a gridded layout. Nature is present throughout the building in materials and textures, with terrace spaces providing breakout areas for social interaction and access to fresh air and planting. Harsh surfaces are avoided in favour of a natural palette, made up of warm whites, creams and timber. Privacy is introduced to large areas of existing street-level glazing by corrugated perforated panels which screen the offices within while also forming a new prominent entrance portal and security gates.
