The basement of a shop in Hove is to be converted into a yoga studio.
Neighbours were worried about noise, especially late in the evening, if the basement of Bang & Olufsen becomes an exercise studio.
The owners agreed to close at 8pm, Brighton and Hove City Council planning committee was told on Wednesday (September 12).
And they said that classes held there would be for no more than ten people, with no gym equipment.
The activities would be restricted to yoga, pilates, meditation, tai chi and ante-natal and post-natal classes.
And people using the studio would go in and out through Albert Mews, at the rear of the building.
Conservative councillor Andrew Wealls addressed the planning committee at Hove Town Hall on behalf of neighbours.
He welcomed the reduction in hours from 9pm to 8pm, saying that quite a few people had bedrooms overlooking the site.
He said: “I appreciate the conditions here in terms of doors and windows are closed when music is played.
“My big concern is a fitness studio operating in temperatures … like those we have seen this summer. Is that realistic?”
He was also concerned about the noise made by people as they arrived for classes and left afterwards.
Planning agent Paul Burgess, speaking for the applicant, said that there would not be large groups or classes at the venue.
He said that there would be a maximum of ten people.
Labour councillor Penny Gilbey said that she enjoyed the music from exercise classes within five metres of her home.
Fellow Labour councillor Claire Moonan said: “Myself and Councillor Wealls will be closely monitoring this with residents.
“I am concerned about the space and, by the end of 12 hours, the smells. They will want air conditioning.”
No air conditioning was included in the application.
The plans were approved with conditions, including that the premises close at 8pm and are restricted to quiet classes.
Conservative councillor Carol Theobald voted against the scheme.
