At present, the Revolution bar in the Plaza, Fitzwilliam Street, serves alcohol until midnight. However, it has applied to serve drinks until 1.30am and remain open until half-an-hour later than that every night of the week.

The application has met with objections from not just residents of the nearby West One apartments, but an environmental health officer from Sheffield Council who says he has concerns about "the potential for noise breakout" and "noise from customers outside the premises".

The officer, Jonathan Round, said the bar was in an area of the city centre that has "relatively low background noise levels throughout the late evening" and there have already been complaints about noise coming both from inside the bar itself and from drinkers outside the premises.

He added: "I am currently investigating a complaint about the breakout of music during regulated entertainment.

"Opening the premises later could also mean that the noise of patrons dispersing from the premises will potentially continue later into the night."

One resident of the West One apartments said that noise from Revolution was already "a real problem".

He added: "This escaped noise is particularly bad on weekends as the music is set to a louder volume.

"The loud music, in particularly the deep bass tones that are constantly emitted from these premises and reverberate around the Plaza is already excessive.

"To be honest, you expect this on weekends and midnight is acceptable for city centre living, but allowing this to continue up to 2am every weekend and weeknight would seriously affect the quality of life for many residents.

"Currently I don't go to bed on a weekend until after closing time, due to the noise from the premises and patrons.

"Allowing this to continue until 2am within a residential area is completely unacceptable."

Another resident of West One said that noise from the bars and restaurants in the Plaza had been adversely affecting herself and her neighbours for some time.

She said: "Complaint after complaint has been made to the council regarding noise disturbance, anti-social behaviour, breaches of various conditions and licensing laws.

"Nothing is done and, as a result, residents' quality of life is seriously impaired."

Another resident said: "Revolution is a bar, not a restaurant, and it clearly wants to be a nightclub. It is therefore in the wrong location."

Revolution, meanwhile, says it "seeks first to meet the needs and desires of the surrounding population" and aspires to be a place that "fits the community and is seen as part of the community".

It also said that there were measures in place to tackle excessive noise, such as noise limitation devices and a "sound web system" which allows music to be played at different levels throughout the premises.

Door staff are also instructed to tell people to leave the bar quietly, it said, and there are signs in the premises to remind drinkers to have consideration for local residents.

A decision on Revolution's application for extended opening hours will be made at a meeting of Sheffield Council's licensing board on Tuesday, November 25 at Sheffield Town Hall at 10am.
