Developer Therme will now submit reworked plans for the water complex at TraffordCity in a matter of weeks.
The overall design for the 28-acre complex has shifted from a single building with a vast undulating full-glass roof and facade to a series of connected roofed pavilions.
This reduces the steelwork involved in the project. The overall size of the scheme remains the same.
Therme has been revising its plans since gaining planning permission three years ago for the £250m to build being brought forward in partnership with Peel L&P.
Therme Manchester is expected to become one of the top 3 all season water-based destinations in the world.
Construction is still planned to begin this year with a build time of around two years.
In addition to a ‘next generation’ waterpark with 25 pools and more than 35 waterslides there will be thermal bathing and a wellbeing spa.
A new multi-storey car park removes the need for under-venue parking, cutting the depth of excavation needed, and simplifying the build process.
