Reef Group, Cavendish Square, London

Our project at Cavendish Square in London with the developers, Reef Group, has recently been submitted for Planning.  This unusual scheme with an investment in excess of £100m involves the redevelopment of an existing underground car park in central London and comprises the demolition of the existing car park buildings and internal below ground floors and the creation of a subterranean extension to create 280,000 ft² of space over four levels of mixed use development which will include healthcare, retail, office and ancillary uses.

This is an extremely challenging site as all plant has to be below ground with very limited above ground construction allowed within the Square and the scheme has to achieve net zero carbon, in line with the new London Plan.  Plans for the scheme have been submitted to Westminster City Council and, subject to planning approval, construction is expected to start on site in late 2020, with completion in 2022. Reef Group is in active discussions with a range of exciting occupiers who could move into the space.

The development will expand the footprint of the Harley Street Medical Area and deliver much needed specialist facilities for London’s growing independent healthcare market.  There will be a strong wellbeing and sustainability theme throughout.

First landscaped in 1729, Cavendish Square is one of London’s original Georgian squares, but in 1969 the site was significantly disrupted and lost much of its connection with the surrounding area when the current car park was constructed.  The plans for the Square will enhance the above ground park and surrounding public realm and will be one of London’s most sustainable developments, reducing traffic volumes and reusing much of the existing car park structure.
