Plans to build 64 floating homes, as part of a 92 berth marina development on the Surbiton filter beds site have been rejected by a planning inspector today.
Cascina Ltd and Hydro Properties would have also built a nature reserve, a restaurant, a riverside walk, and a heritage and education centre, as well as a contribution of £219,000 towards building affordable housing.
Inspector Lesley Coffey returned her verdict today after hearing evidence from the company and campaigners in November.
She wrote: "The benefits that would be delivered by the proposal are considerable, however they must be weighed against the substantial harm to the metropolitan open land and character and appearance of the area.
Whilst the proposal would not harm the setting of the listed buildings in the locality, I attach significant weight to the harm to the character and appearance of the surrounding area."
Kingston Council leader Liz Green said: "I'm delighted that the council decision has been upheld.
"We can now, working with the Friends of Seething Wells, work on the plan of what should happen to the site.
"I’m really pleased the Planning Inspectorate has listened to the arguments put forth.
"I think that’s absolutely the right decision."
