Fitzhardinge Street is a short but well-proportioned street at the centre of Marylebone W1H, running between Manchester Square to the north and Portman Square to the south. The street takes its name from a family connected by ancestry to the Portmans, whose estate developed this part of Marylebone from the 1760s onwards under the direction of Henry William Portman. It is characteristic of the estate's practice of naming streets after family members and related lineages rather than local geographical features.
The buildings on Fitzhardinge Street are Grade II listed Georgian structures, recognised for their architectural integrity and their contribution to one of the most complete surviving sequences of Georgian terraced housing in central London. The street sits within the Portman Estate's conservation area, where Westminster City Council imposes strict controls over alterations to facades, ironwork, and proportions.
Today the street accommodates a mixture of managed residential apartments and office space, consistent with the Portman Estate's active stewardship of its portfolio. The nearest Underground stations are Bond Street and Marble Arch, both within a short walk. The immediate neighbourhood, bounded by Manchester Square to the north and the broader Portman Estate to the west, is among the more sheltered and composed corners of Marylebone, with limited through-traffic and a predominantly professional occupier base.
