Work is set to begin on a £2.5m redevelopment of Hambleton Leisure Centre in Northallerton, North Yorkshire.

Facility development specialist Alliance Leisure – which is leading the six-month project – has appointed contractor ISG to undertake the work, which will result in a new 5,100sq ft (473sq m) extension.

The new complex will house a new health club and toning area, with the current gym space being converted into group exercise studios, including an immersive indoor cycling studio.

New energy-efficient lighting will also be installed in the sports hall and the timber sprung floor will be upgraded.

The refurbishment of the existing centre will include repair and upgrade works to the existing water slides, flumes and wave machine in the pool area. The changing facilities will also be upgraded with the addition of a new members’ change area.

“Our team will be working in a live environment," said Andy McLinden, managing director of ISG’s UK Construction North and Scotland business.

“We have had an agreement with Alliance Leisure since 2010, which is built around Sport England’s need to engage people in fitness initiatives. This is putting government-funded provision in direct competition with the commercial sector as they now boast top of the range facilities.”

The majority of the project’s cost, £2.2m, has been provided by Hambleton District Council – which owns and operates the centre.

The council also secured a £213,000 investment of National Lottery funding from Sport England for the scheme – one of 19 schemes supported nationally as part of a £6.5m funding round in 2016.
