In the heart of Mayfair, London, 51 Charles Street is a grand building amongst a smorgasbord of other architectural gems where the Block Compliance team conducted extensive communal fire door surveys.
It is one of many Georgian properties, typical of the area, and is rightly Grade II listed (but only since 2000). It forms an integral part of the Berkeley Estate and is estimated to have been completed by around 1750, with Berkeley Square and the prestigious Bruton Street and Bruton Place a short distance away.
Charles Street, itself, despite not appearing on Monopoly boards, is grand in every sense and has many illustrious neighbouring properties with famous residents:
- At 22 Charles Street, the Duke of Clarence, who would later become King William IV, before his accession to the throne, resided here.
- Dartmouth House at numbers 37–38 was originally two mid-18th-century homes combined in the late 19th century by the banker Edward Baring, 1st Baron Revelstoke, and remodelled in a Rococo style; today it serves as the headquarters of the English-Speaking Union.
- Other houses – namely 39, 40, and 41 – also date from around 1750–1753 and are Grade II listed as is No. 16, built in 1753 for Francis Willoughby and later home to the Craven family, with a rich history of royal and elite visitors.No. 48 is a Grade II listed townhouse dating from around 1750–53, likely constructed by John Phillips in partnership with George Shakespear. Notably, it was once owned (from 1874 to 1879) by Lord and Lady Randolph Churchill, parents of Winston Churchill.
- The street also retains cultural touches: the private members’ club Mark’s Club at 46 Charles Street was founded by Mark Birley in 1972 and occupies a townhouse close to both the Running Footman pub and Berkeley Square.
- Add in The Running Footman, a pub tracing its name and history back to the era of footman-servants running ahead of their masters’ coaches, and the street becomes a terrific tableau of architectural and social heritage.
- Its character is further enriched by its proximity to Berkeley Square and landmarks like Dartmouth House.
Our team always feel very privileged to work in areas of architectural beauty, like Charles Street

As you can see from the photos and reel on our Instagram and LinkedIn channels, it is a beauty.
The façade, rendered in red-brown and buff-stock brick with stone and stucco accents, is topped by a slate mansard roof. The house spans four storeys above a basement, organiaed into three bays, with its entrance subtly placed to the left. Decorative sash windows with architraves, cast-iron balconies, a moulded cornice, and a dormer with bracket supports its refined Georgian elegance.
Inside, the house continues to impress with exceptional period craftsmanship.
An open-string staircase, complete with chinoiserie tread ends (meaning the carved or painted decorations on the ends of the stair steps were done in this whimsical East Asian–inspired style, adding a fashionable and exotic flourish to the otherwise Georgian interior) and a mahogany balustrade, features 18th- and 19th-century newels that articulate its evolution.
Four-panel doors maintain the historic character throughout.

Communal Fire Door Surveys
At Block Compliance Ltd, we know that fire doors are one of the most important safety features in any building. In communal areas such as stairwells, lobbies, and corridors, they play a crucial role in holding back smoke and fire, protecting escape routes, and giving people valuable time to evacuate safely.
A single faulty door can compromise an entire fire strategy. That’s why regular communal fire door surveys are now a legal requirement under the latest fire safety regulations and why we provide thorough, reliable inspections designed to keep your building compliant and your residents safe.
Our expert surveyors carefully check every aspect of each fire door set, from frames and hinges to closers, glazing, seals, and signage. We record any defects, highlight compliance gaps, and give you a clear, prioritised action plan so you know exactly what needs fixing and when. Every survey comes with a detailed report, providing full evidence for your fire safety records and regulatory audits.
With new duties now requiring responsible persons to carry out regular checks of communal fire doors, Block Compliance Ltd makes it simple to stay ahead of the law.
