Project Value

60% Less Energy

Than Standard Leisure CENTRES


passivhaus facility

Spelthorne Leisure Centre

One of the world's most advanced, energy efficient Passivhaus leisure centres.

We are working with Spelthorne Borough Council to deliver one of the world's most energy efficient leisure facilities, one designed to meet stringent Passivhaus criteria.

Once complete, it will be the UK's largest wet and dry leisure centre to achieve Passivhaus, and the first in London. Designed by GT3 Architects, the building is designed to consume up to 60% less energy compared with a standard new building.

Local residents will benefit from an eight lane 25m main pool, learner pool, splash pad and spa. Further sports facilities include a 6-court sports hall, three squash courts, 950 square metres of fitness space, two studios, one spin studio and a multi-use room which combines to create two further badminton courts.

There will also be an open plan café and reception space, along with a roof terrace overlooking four small-sided 3G football pitches.

How low-carbon has become the future of leisure

Commencing the project, Daniel Mouawad, Chief Executive of Spelthorne Borough Council, said:

“We are delighted to be a pioneering authority, demonstrating our commitment to net zero by building an ultra-low Passivhaus leisure centre. Having declared a climate emergency, we recognise the need to lead by example to achieve cleaner and greener lifestyles and a sustainable borough for all to enjoy.
This centre is a great example of partnership working and will provide the right infrastructure to meet our communities’ changing needs and will enable residents to stay active in a healthy environment, with low chemical pools and a dementia friendly design.”

Roger Forsdyke, managing director of Willmott Dixon's London and South business, said:

“We are hugely excited to be working alongside Spelthorne Borough Council, GT3 and Gale and Snowden on what will be a landmark project. Spelthorne Borough Council’s choice to adopt the Passivhaus approach is a testament to their commitment to carbon reduction."

Mark Gowdridge, director at GT3 Architects, said:

“It’s great to see the progression of this fantastic project, and especially to have the team at Willmott Dixon now joining us with their wealth of knowledge in sustainable construction.
“We are working ever closer to the Passivhaus certification for our design, which will save up to 60% in energy costs and ensure the building is futureproofed. We’re very happy with how the project is moving and having the input of Willmott Dixon will only enhance this. We are very much looking forward to bringing a fundamental space for health and wellbeing to the surrounding community.”
