Families fear they will be kept up all hours after plans for a �2million night club by the Olympic Park was given the go-ahead last night.

Residents on Fish Island accused the London Thames Gateway Corporation of “putting profit before their health and well-being” after they approved the proposal last week to convert a Victorian stable block into a night club for two months around the time of the Olympics.

The site at Swan Wharf which will hold 3,750 people will stay open until 2am seven days a week with party-goers leaving the island by water taxi.

Chair of the Association of Ironworks Residents, Michelle Gabriel, said: “Our sleep could be restricted to four hours a night. It could take two hours to empty the venue after it closes and get people onto water taxis, and deliveries start at 7am.

“We always knew there would be an impact from the Olympics but this would affect our sleep every day for two months. There are families with young children and we all have jobs to get up for.”

Ms Gabriel hit out at the Corporation for not accepting Tower Hamlets council’s advice to restrict opening hours to 11pm.

She also said it failed to consider suggestions from residents such as to reduce its operation to during the Olympics and Paralympics giving residents two weeks’ breathing space in between.

Tower Hamlets Labour councillor Marc Francis said: “I’m very disappointed with the outcome and think it’s outrageous to put a night club just 10 meters from residents. But it’s not fair to say there wasn’t a considerate debate.

“But it’s not over yet, they still need the council to approve late licensing hours and I’ll be opposing it. I think an 11pm finish at least on weekdays would be more acceptable.”

Associate planner at consultants Montagu Evans, Simon Marks, said: “We’ve reduced the original opening from 4am to 2am which ties in with events at the Olympics which also go on until then.

“We’ll consult with environmental officers at Tower Hamlets council about monitoring noise level. There will be various types of sound proofing at the venue still to be agreed. There will be lots of people in the area already with the Olympics and it’s an industrial area where deliveries are already taking place.”

Mr Marks said the �2million investment in converting the site would not be “financially viable” unless it could stay open for two months.

He said owners Surrey Vale had no intention of keeping it as an entertainment venue after the Games. But he said the investment would help kick-start regeneration in the area and provide local jobs.
