From underground car park to ‘wellbeing centre’: £100m Mayfair scheme set for OK


Plans to transform an underground car park in Mayfair to an £100 million ‘wellbeing-focused’ centre are set to get planning consent at a planning subcommittee this evening (28 April)

Cavendish Square, behind John Lewis on Oxford Street, was built in 1729 and has sat above an underground car park since 1969.

But now the public park is set to be revamped while the three subterranean, doughnut-shaped floors are retrofitted into a shopping and leisure centre.

The scheme, which is being brought forward by a joint venture between Westminster City Council and Reef Group, will also see the excavation of a fourth below-level floor.

The 26,000m² development has been designed by UrbanR, a subsidiary of Reef Group led by ex-Make partner Sam Potter.

Westminster Council has said it sees the centre as an ‘oasis’ from the bustling Oxford Street, with space for visitors and locals to enjoyed ‘well-being focused’ mixed uses and ‘enhanced public realm’.

The scheme would feature three new ‘entrance pavilions’, on Regent Street, Harley Street and Oxford Street, which also serve as lightwells, with ‘sun-burst fenestration’.

Planners at the the council have backed the scheme, saying it should be given permission subject to an index-linked payment to the authority’s affordable housing fund.

Work is set to start on the project later this year, pending approval from the Mayor of London.

  • Just about everywhere else in Britain the retail sector is struggling to keep its head above water, but in central London there seems to be an insatiable appetite for more shopping 'experiences'.
    Is this sustainable, or is the plague's likely impact on mass tourism threatening to turn it into a white elephant?
