A popular bar in Richmond will not be allowed to extend its opening hours after councillors heard about complaints of “drunken mayhem”, noisy extractor fans, and even cases of people urinating and defecating in an alleyway outside.

Neighbour of Revolution Bar, Karen Steidle, said the noise is “unrelenting, like a jumbo jet”, and that she hasn’t had an uninterrupted night’s sleep in seven years.

She complained that revellers are often rowdy, and that the fans for the building are outdated and noisy, and whir throughout the night.

She also claims patrons leave mess and bottles behind at closing time, and likened the lines of bottles on the street to “living in a brewery”.

Applicants for the bar, one of more than 55 Richmond Bars across the country, asked to extend its weekend hours, staying open until 12:30am on Friday and Saturday nights, and midnight on Sunday.

Revolution wanted to extend its alcohol and music license to midnight on Friday and Saturday and 11:30pm on Sunday.

The application received nine objections from residents.

Felicity Tulloch, representing Revolution, said: “Much has been made of the licensing history, which was seven to eight years ago now,” and insisted the new Chief Executive had “really turned around” the bar.

She pointed out the Metropolitan Police had made no representation against the extension, and that the bar wanted to extend its opening hours to remain competitive and allow for a more gradual dispersal of customers.

She added that Revolution was “looking into” the noise problems with the fans, and said they would be automatically switched off at 11pm.

“My clients want to be good neighbours, they have heard the resident and will do everything in their powers that she is not unduly disturbed,” she said.

However councillors were not convinced.

Reading the decision, Chair Councillor Helen Lee-Parsons said the council had refused the application due to the “cumulative impact” of more bars staying open late.

She added that the plans for more seating had contributed “no material change” and that the committee was not satisfied the measures proposed were sufficient to mitigate the extended opening hours.

The committee was concerned about the reports of public nuisance and complaints about the air conditioning system which had not been resolved, despite coming up at a previous hearing in 2017.

She concluded that the committee “was not satisfied current management can successfully manage additional hours without impacting on the licensing objectives.”

The bar will get a chance to appeal the decision.
