The Therme Manchester project located in Trafford City has reached a new milestone. Sir Robert McAlpine has been appointed construction manager. The £450 million development will deliver the UK’s first urban wellbeing resort of its kind.
A Project Years in the Making
The scheme was first approved in 2020. Since then, it has undergone several redesigns. Further, in 2023, a major refresh introduced new features and eco-focused adjustments. Another amendment in 2024 further refined the layout and sustainability goals.

Resort Features and Visitor Experience
Once complete, the resort will offer more than 25 waterslides and 10 pools. What’s more, it will include the UK’s largest sauna, immersive art spaces, and a landscaped wellbeing garden. Visitors can also expect botanic areas and family-friendly activity zones, adding to the wave of leisure investments in the country such as Universal’s planned first European theme park in the UK.
Design Evolution and Connectivity
Additionally, the original single-glass dome was replaced with pavilion-style buildings. This change reduces environmental impact and improves energy efficiency. The site will link to the Bee Network, Metrolink, and local walking routes. A new multi-storey car park is also planned.
