More details of a major expansion at London Heliport in Battersea have been announced.

The plans will include a 70-bedroom luxury boutique-style hotel.

It will also house a state-of-the-art executive aviation facility, providing panoramic views across the heliport and River Thames.

There will also be meeting and conference rooms and VIP lounges.

Details were announced at the start of a two-day business travel show at Earl's Court.

The work should be finished by spring 2009.
