Residents living in darkness due to a recently built wall in front of their windows have taken legal action against a Fortitude Valley bar and the Brisbane City Council.

The eight tenants want the 9.5-metre high "acoustic wall" removed, after it was legally put up one metre from their building without any consultation from Fringe Bar.

The solid wall was designed to prevent noise complaints and was erected late last year. Former tenants of the Freedman building on Ann St had previously made complaints against the bar.

Documents lodged in Queensland's Planning and Environment Court show the residents are seeking a ruling that the council decision to approve the wall was invalid. They are also seeking costs from the council and Fringe Bar's owners, Fitzgibbons Hotels.
