McLaren started on site last month on its £57m construction contract for developer Cathedral who have now secured an investment of £54.9m from Hermes to help deliver the regeneration scheme.
Cathedral said the move “provides forward funding for the commercial element of the scheme, 85% which is pre-let.”
The scheme has also been back by the Homes and Communities Agency which has invested £9.5m through its Get Britain Building funding programme.
Bromley South Central scheme is designed to kick start the regeneration of the South end of Bromley High Street.
McLaren is building a new residential and leisure quarter with a landscaped public square surrounded by a nine screen multiplex cinema, 25,000 sq ft of cafés and restaurants, a 130-bedroom business hotel, 200 private and affordable apartments and a new 400 space secure underground car park.
