A shining light in the regeneration of RopeWalk’s Conservation Area in Liverpool, 90 Duke Street is the new purpose-built headquarters for Atlantic Container Lines (ACL). Comprising 62,000 sq ft of Grade A office space across four floors, the building blends a contemporary glazed entrance lobby inviting light into the space and a renovated former vinegar warehouse at the rear. The building is centred around an external courtyard which acts as a social meeting point for the workplace. In response to the area’s Victorian buildings, the Duke Street façade is designed as the principal elevation, with a recessed ground floor, bronze-clad attic storey and double-height vertical glazed openings to the intermediate floors. The side and rear elevations carry simpler design in brick and glazing. Their interiors benefit from floods of light provided by splayed reveals along the Suffolk Street façade.
