Banque Paribas

The headquarters replaces previous 1960s office blocks on the site, which is to the north of Marylebone Station. The office building is to the south of the site, and a new residential block, part of the same development, to the north.

The office building comprises an 80m x 80m block of five floors rising to a main parapet level of 23.5m, with two further, annular floors set back behind a roof terrace and the whole surmounted by a 26m-diameter dome.

A projecting three-storey bay window structure, glazed from floor to ceiling, surmounts the two-storey, ground- and first-floor base. The 3m module on Harewood Avenue is carried around the other elevations with a similar 6m bay. These projecting bays are carried up into a deep cornice at parapet level, producing a modelled, almost crenellated, skyline.

The reconstituted stone cladding, using a range of naturally red and buff-coloured limestone aggregates and the French 'Rochebelle Rose' flamed limestone from the Macon area, gives the facade a unifying colour which relates to the adjoining Marylebone Station and Landmark Hotel.
