27-37, LOWER REGENT STREET SW1 (See details for further address information)

Nos 27 to 37 on Lower Regent Street, built around 1910-1920 by Sir Reginald Blomfield, are a group of offices and shops that form part of the grand redevelopment of Regent Street Quadrant and the reorganization of Piccadilly Circus. The building is constructed from Portland ashlar, rusticated up to the second floor, and sits on a steel frame with a slate roof. It showcases Beaux Arts inspired classicism in a grand style, similar to the former Swan and Edgar block and the County Fire Office, and it balances the nearly identical Nos. 24 to 36 opposite, framing the southern entrance to Piccadilly Circus.

The structure has six storeys, including a podium ground floor, a mezzanine, and an attic storey with a dormered mansard roof. It features eight windows across (arranged 1:6:1) with prominent end pavilions that return to the north, creating a two-window wing facing the Circus and a five-window wing facing Jermyn Street. The entrances and shops on the ground floor, which were modified in the mid to late 20th century, are set between rusticated pilasters that rise through the rusticated mezzanine and low second floor, culminating in a modified cornice. The ground floor and mezzanine in the pavilions are contained within large semicircular arches adorned with helmeted heads mounted on keys, flanked by swags.

Recessed sash windows are framed simply, while the principal windows of the pavilions extend through the third and fourth floors, featuring segmental arched architraves and open pediments on consoles, along with ornate cast iron balconettes. The pavilions are accentuated by channelled quoins and heavy attics topped with open segmental pediments. A bracketed main cornice supports a balustraded parapet over the main range. The mansard roof includes lead-dressed oval dormers flanked by scrolls and lead-capped ridges. The Jermyn Street return displays small vermiculated tooling on the podium, and from the second floor upwards, the windows are vertically linked in shallow panels, topped by a deep enriched crowning cornice.
