Arts Team @ RHWL has won the go-ahead to redevelop Finsbury Town Hall, the Grade II*-listed building sited opposite the Rosebery Avenue home of the AJ.
Islington councillors last week gave planning permission and listed building consent to the practice's £1.9 million proposals to reuse the building as a school of dance for the Urdang Academy.
The Victorian town hall - listed on English Heritage's Buildings at Risk Register - will be brought back into community use after standing empty for several years.
Included in the designs for the town hall are plans for seven studios, a gym, health and treatment rooms and a cafeteria.
Principal arts team director Barry Pritchard said the scheme was essential for the surrounding area and regeneration.
'Unlike private housing or private offices, the building will have a community role to play. It will be available for public viewing - bringing the building back into use, ' he said.
Detailed designs are now being finalised for the project and additional funding is being sought for restoration of the Great Hall and other public areas.
