A new sports facility is to be built in King's Cross, London, as part of a building housing a number of public services in one location after planning permission was granted.

King's Cross Central Limited Partnership (KCCLP) submitted plans for the Three Pancras Square development, which were given the green light by Camden Council on 3 November.

The council is working with KCCLP to deliver the LA Architects-designed project, which is to feature a two-floor sports centre with 25m, five-lane swimming pool.

A small recreational lagoon-style pool; a poolside spa area with sauna and steamroom; and a gym to incorporate more than 100 stations are also planned, along with two exercise studios.

Meanwhile, the development will also house other local authority-run operations, including a library and a customer contact centre, and will help save £77m on maintaining existing sites.

A council spokesperson said: "The new sustainable building, built to high green standards, will be at the heart of the wider Kings Cross development at Pancras Square.

"The sale/termination of leases at seven existing buildings together with savings on running costs will pay for the new facility."

It is anticipated that work will commence early next year, with the new facilities scheduled to open in summer 2014.
