Alliance Leisure Completes £15m Transformation at Doncaster Dome

Alliance Leisure are excited to announce the completion of works to the Lagoons at Doncaster Dome, on behalf of Doncaster Culture and Leisure Trust, funded by City of Doncaster Council.

The newly redeveloped Lagoons represent a significant milestone in the regeneration vision for the iconic leisure destination.

The project was procured through the UK Leisure Framework, owned and managed by Denbighshire Leisure Ltd (DLL), and was delivered in partnership with project managers Abacus, principal contractor Universal, architects Saunders Boston and specialist pool partner Myrtha Pools, plus CGP and Hensall delivering M&E services.

The redevelopment modernises one of the Dome's most popular attractions, enhancing the visitor experience while securing the long-term future of the facility for the local community.

Two new racer slides and a new indoor splash play area with a variety of interactive water features form part of the extensive programme of upgrades which have taken place over the past 18 months.

Major works have also been undertaken to replace the glazing, redesign the main entrance area and install new heating and ventilation systems responsible for heating and maintaining water and air quality within the swimming pool environment.

The project has aimed to modernise the pool complex, while preserving the character of the Grade II listed building, which opened in 1989 and was listed in 2023 becoming one of the youngest listed buildings in the country.

Sean Nolan, Regional Director at Alliance Leisure, said: "This has been an ambitious and technically complex project delivered in a live operational environment, and we are incredibly proud to have reached completion alongside our delivery partners. The revitalised Lagoons are a fantastic example of how investment in community leisure infrastructure can revitalise and protect key local assets and create experiences that will benefit generations to come."
