53 And 55, Great Cumberland Place W1

Nos. 53 and 55 Great Cumberland Place are terraced townhouses built around 1811 to 1820 as part of the Portman Estate development linked to J. Parkinson's Bryanston Square. The houses are constructed of stock brick with channelled stucco on the ground floors and have concealed slate roofs. They rise five storeys with basements and each has three windows across the front.

The doorways are semicircular arched, with No. 53 featuring a panelled door and fanlight, while No. 55 has been altered. The upper floors have recessed sash windows set under flat gauged arches, with No. 55 having red brick arches. Notably, No. 53 has a mid-19th century channelled stucco canted bay that replaces the central and right-hand windows from the ground to the second floor, topped with a cornice and blocking course. Both houses are crowned with a dentil cornice and blocking course.

They also feature original cast iron balconies with geometric patterns on the first floor, as well as cast iron area railings with spearhead designs and urn finials. Nos. 53 and 55 share the same architectural style as Nos. 57 to 63 (odd), which are also noted for their continuous cornice. These houses are included in the listing for their group value.
