Independent health club operator Third Space has opened its second site - at the The Marylebone Hotel in London.

The club has rented out a 15,000sq m (1,400sq m) space at the hotel, which is owned by The Doyle Collection. According to chief executive Eric Dunmore the club cost "around £2m" to set up.

Facilities include an 18 metre ozone-treated swimming pool and Third Space's first full service spa.

The gym has been equipped with Technogym equipment and also includes a free weights studio and Powerplate Zone as well as a group exercise room offering combat, dance, Pilates and yoga.

The club also houses a two-storey training concept called 'Retro Gym', a concept that fuses modern functional techniques with traditional equipment including 'old-school favourites' such as climbing ropes, beams and bars.

The spa@THirdSpace offers sauna and steamroom and a treatment menu supplied by French company Payot.

The opening is part of Third Space's expansion plans which include a number of new sites in the capital.

In an interview with Health Club Management (November/December 2010, pp.28-31) Dunmore revealed that the chain was now looking to implement its roll out plans that were delayed by the economic downturn.

"There's plenty of opportunity in London and that will be my focus. I'd like to be in Chelsea and maybe somewhere in the City, although that's a hard environment," he added.

"Clapham would be great, and perhaps London Bridge. Even Richmond or Greenwich in due course."
