Pearl Mayfair

Opening 26 September 2026

Blink and you could miss it. Between Grosvenor Square and Oxford Street, just opposite The Beaumont, a dozen or so steps lead to one of Mayfair’s beautiful little secrets. Brown Hart Gardens is neither quite at street level nor a rooftop garden in the usual sense: a raised terrace sitting on top of a Grade II-listed working electricity substation. Here, among the newly planted gardens, is Pearl.

The setting has always had a certain eccentricity. There were communal gardens here before the substation arrived in the early 1900s and, when they were displaced, the Duke of Westminster insisted on putting them back — on the roof. More than a century later they have been replanted by the late Nigel Dunnett, in one of his final landscape projects, bringing his characteristically naturalistic approach to this rather unexpected corner of Mayfair.

Pearl belongs to The Beaumont but sits apart from the hotel, in the pavilion at the Beaumont end of the gardens. Studio Ageli has worked with the original structure, adding a generous roof light and curved glass overlooking the planting; inside are pale, pearlescent finishes and works by Jemma Powell and Valéria Nascimento. On a fine day, however, the terrace may well be the table to have, extending into the gardens with Milanese piazzas and the Italian Riviera among the references.

Lisa Goodwin-Allen, Culinary Director at The Beaumont, is in charge of the food and has looked south too, across the Mediterranean. Burrata comes with grilled peppers, artichokes and hazelnuts; octopus with ’nduja aioli; grilled swordfish with preserved lemon and parsley; and lamb chops with sumac, tzatziki and dill. Pearl is open from breakfast through to dinner.
