Plans for two entertainment venues near the Olympic Park have sparked opposition from a residents’ group which says they will cause “unimaginable noise and disruption”.

Developers are seeking permission to convert two warehouses in Fish Island into temporary venues which will cater for up to 12,000 delegates, athletes and journalists.

But some residents living in the nearby Ironworks complex say the proposed 4am closing times are too late and argue the area is not appropriate for such large crowds.

The larger development by luxury food firm Formans would be 50 metres from homes and the smaller one, at Swan Wharf, 10 metres.

Michelle Gabriel, honorary chair of the Ironworks residents’ association, said: “We can’t imagine that number of people at clubs here and the noise will impact on people’s ability to sleep.

“Transport is another issue. There are poor transport links at Fish Island and the extra visitors and deliveries would clog up the island. About four protected trees would go, too.”

The venues would be open for the duration of the Olympics and Paralympics and possibly a few weeks either side.

But Formans, which has been on the site for more than 100 years, said Fish Island is so close to the Olympic Park that there will be inevitable disruption from the Games themselves.

Owner Lance Forman said: “We don’t believe there will be massive noise disturbance because there will be media organisations here and they won’t be able to work if it’s noisy.

“You have to accept that this massive festival will be happening on your doorstep and it’s unrealistic to think life is going to be normal for those two weeks.

“We have very good relations with our neighbours and we believe most people are embracing the events.”

Forman’s added that it has invited the group to chat about their concerns.

It said the late finishing is because timings are controlled by American television and added it was advised to allow guests to leave gradually to ease congestion.
