No. 5, Hamilton Place

No. 5 Hamilton Place is an end-of-terrace town mansion built between 1807 and 1810, likely designed by Thomas Leverton. It underwent significant remodeling from 1879 to 1881 by W.R. Rogers of Messrs. William Cubitt for Leopold de Rothschild. The building is clad in Portland stone and features a slate roof, showcasing a rich Venetian Renaissance architectural style.

It stands four storeys high with a basement and a dormered mansard roof. The facade is four windows wide, with full-height three-window bows on both the front and a bold two-storey projection on the Park Lane and north elevations, creating a terrace effect on the second floor. The entrance is located in a porch on the left side, featuring an Ionic order that frames semicircular arched ground floor windows.

The first and second floors have a superimposed sequence of orders with archivolt arched windows, displaying Composite over Corinthian styles, while the third floor features camber-headed lugged architrave windows. An enriched entablature and balustrade adorn the first floor, topped by a crowning cornice and balustraded parapet. The entrance and Park Lane fronts display engaged orders, while the north elevation features free-standing and coupled columns and pilasters. The first-floor windows on all three elevations are protected by intricately scrolled iron guards, and elaborate cast iron area railings enhance the exterior.

Inside, the decoration was carried out by the firm of John Jackson, Mellier, Forsythe, showcasing a rich and eclectic mix of fin de siècle Louis XV and Renaissance styles with exceptional craftsmanship. The top-lit stair compartment features an enriched cut string to the oak stairs, complemented by an intricately scrolled balustrade. The walls are panelled in Regence-Louis XV style boiseries with tapestry insets, and the library woodwork was crafted in Florence by Chevalier Rinaldo Barbetti, featuring French Renaissance style panelling and plasterwork in the ground floor front room.
