On a quiet side street in Clerkenwell, a former 18th-century ironmonger’s workshop is the subject of this exceptional renovation by Michaelis Boyd Architects. The result is a refined environment across almost 4,200 sq ft of internal space, with terraces on three levels, expansive receptions on two, four bedrooms and a ground level cleverly arranged around a central lightwell. It offers great versatility in potential arrangements and includes a garage, with a car stacker, at street level.
