Clarendon House

Clarendon House was a grand town mansion that once stood on Piccadilly in the City of Westminster. Built in the 1660s for Edward Hyde, the first Earl of Clarendon, it was the largest private residence in London at the time. The house occupied an eight-acre site granted by the king, set well back from the street behind a courtyard. Designed by Roger Pratt, it featured a symmetrical classical style with a flat, balustraded roof and a central cupola. The building followed the double-pile plan, with two main storeys and a raised basement, totalling 101 hearths. The house’s grandeur and cost—around £40,000—sparked resentment, contributing to Clarendon’s downfall in 1667. Contemporary diarist Samuel Pepys recorded vandalism at the property, where crowds cut down trees and broke windows. Architectural critics later praised it; John Evelyn called it the finest house in England, while John Summerson ranked it among the first great classical London mansions. Its design influenced later country houses, notably Belton House in Lincolnshire. Though demolished in 1683, the site later gave way to Dover Street, Albemarle Street, and Bond Street. The mansion’s legacy endures in the streets that replaced it, marking a key moment in London’s aristocratic development. Its story also features in Susanna Gregory’s historical mystery novel *The Piccadilly Plot*. The area’s transformation from rural lane to elite district reflects Clarendon House’s pivotal role in London’s architectural and social history.
