St Marylebone Library And Health Centre

St Marylebone Library and Health Centre is a public library built between 1938 and 1939 by Sir Edwin Cooper. The building is constructed of Portland stone and features flat terraced roofs. It presents a stripped cubic style, reminiscent of Cooper's earlier Graeco-Roman Town Hall design. The structure consists of a basement, three storeys, and an attic storey, with a facade that is five windows wide, where the end bays are slightly advanced.

A central tetrastyle portico in antis spans the ground and first floors, slightly overlapping the end bays. This portico is supported by plain shafted giant Corinthian columns and pairs of antae, topped with a deep entablature that has a bracketed cornice and a balustraded parapet adorned with urn-capped dies. The windows are plain, and there is a band course at the second floor level of the end bays and another band course at the second floor parapet.

The attic storey is set back over the end bays but is advanced and slightly taller at the center, aligning with the portico. It features a central thermal window flanked by cartouches and a festooned frieze below the parapet band course. The twelve bay returns have ground and first floor windows that are recessed between plain giant piers. There are two subsidiary doorways with heavy porches facing Upper Montagu Street. Band courses extend from the front to the second floor and parapets.

At the front, there is a stone parapeted area with a flight of steps leading to the portico, which is flanked by bronze lamp standards with bracketed lamps, each topped with small statues of children. The rear part of the east return is connected to Cooper's Town Hall by an arched ashlar bridge at the second floor level, with a stone arched gateway beneath it, leading towards Salisbury Place.
