Brown Hart Gardens, London
Brown Hart Gardens is a distinctive and somewhat hidden street space located in the heart of Mayfair, within the City of Westminster, London. It consists of two short, separate roadways: one lane running eastward from Balderton Street to Duke Street, and another going westward in the opposite direction. Between these lanes lies a raised public terrace known for its unique architectural setting, often referred to as one of Mayfair’s best-kept secrets.
Layout and Surrounding Streets
The configuration of Brown Hart Gardens is unusual. Unlike a typical street with a single continuous carriageway, this location features twin lanes separated by a grand elevated deck that sits atop an electricity substation. To the north and south, it is framed by red-brick Edwardian mansion blocks, creating an enclosed, almost courtyard-like atmosphere. The two traffic lanes connect Balderton Street on the west side with Duke Street to the east, while nearby streets include North Row to the north and Duke Street leading to Grosvenor Square just a block away.
Historical Background
Brown Hart Gardens was laid out in the early 20th century, specifically around 1905–1906, as part of the extensive redevelopment of Mayfair by the Grosvenor Estate. The name ‘Brown Hart’ is believed to derive from the combination of two local publicans—Mr. Brown and Mr. Hart—though this origin is more anecdotal than officially documented. The elevated deck, which forms the focal point of the street, was constructed above a London Electric Supply Corporation substation completed in 1905. This dual-use approach was an innovative solution by the Grosvenor Estate to maintain community space while accommodating new utility infrastructure.
The Elevated Terrace
Perhaps the most notable feature of Brown Hart Gardens is its raised terrace, accessible by staircases at either end. This paved deck area, adorned with planters, benches, and elegant balustrades, offers a quiet retreat from the bustling streets of Mayfair. Originally built as a community amenity to compensate for the lost ground-level garden due to the substation, the terrace has evolved into a popular relaxation spot for locals and visitors alike.
