St George has submitted plans for a 21-storey block of flats in Kingston, south-west London.
The 380-flat scheme has been designed by John Thompson & Partners and Malcolm Fryer Architects.
The listed Post Office and Telephone Exchange will be refurbished and retained to provide office space while office buildings Argyll House and Brook House will be demolished.
The project is located in the Eden Quarter of Kingston town centre, which is a main focus of the council’s regeneration plans.
A decision is expected by mid-March.
