Treasury Holdings has submitted plans for a new riverside park at the site of Battersea Power Station.
The plans will see the area in west London open to the public from July 2011, and will connect the site to the existing park via a walk under Grosvenor Railway Bridge.
Communities secretary Eric Pickles approved the wider redevelopment last month with work scheduled to begin in early 2012.
The scheme, being considered by the London Borough of Wandsworth authorities, is due to be completed in 2016.
The proposal takes in as many as 3,400 new homes, office space and hotels, as well as restaurants, shops, conference facilities and hotel accommodation.
Treasury Holdings planning chief Jeremy Castle said: “Many people have asked us when the power station will be opened to the public.
“Our recently approved plans include a new riverside park, and we are delighted to announce our intention to open part of the park from this summer, and to connect the river walk between Battersea Park and Central London.”
