This is the first picture of plans for a tennis court and swimming pool on top of a redevelopoed Battersea Power Station.

Real Estate Opportunities, which owns the power station site, said the facilities were part of a plan for a health club for residents.

The planning application for the £4billion power station project will be lodged with Wandsworth Council in the next few weeks, but the latest picture comes two weeks after interim financial results showed REO had lost £200million in the first half of the year and was £1.6billion in debt.

Treasury Holdings, which is developing the station site and is 67 per cent owned by REO, maintained it was "full steam ahead" for the development.

Rob Tincknell, UK managing director of Treasury Holdings, said: “We are in a strong position. The property market has dropped but we will be in a good position as it picks up.”

Work on the project is due to start in 2012, if approved, and be completed by 2020.
