160 Old Street is a project which does more with less in every respect. The conversion a 1970s-built office building into a modern commercial scheme fit for the 21st Century involved the addition of 3 floors, infilling lightwells and extending all elevations to significantly increase the lettable floor area.

Using a lightweight steel composite solution to form the new upper floors, and internal zone, minimised the load increase on the existing frame and foundations.

Exposed soffits throughout create an attractive modern industrial warehouse environment. The building has been widely applauded as a thoughtful, intelligent, sustainable and efficient re-modelling of an existing site.
