Plans to build a flat complex including a seven storey tower have been granted on appeal.
The proposals for 39 affordable flats at the former Cover's Yard site in Lewes Road, Brighton, were passed five years after they were first submitted.
The planning inspector granted permission after three planning applications, two public inquiries and significant design changes.
No decision has yet been made on when work will start.
The plans will see a terrace of three-storey flats, a seven-floor apartment tower block and a four-storey residential building constructed in Lewes Road.
Simon Atkins, director of a:b:i:r architects who designed the development for The Hyde Group housing association, said: "We are absolutely delighted that the planning inspectorate has granted permission for this scheme.
"It is a testament to our client's determination that this is the right site for desperately-needed affordable housing and it vindicates our belief in good quality design.
"We hope that this decision will act as a catalyst for the regeneration of the Lewes Road area."
A spokesman for Brighton and Hove City Council said: "Although we turned the building down because of differences of opinion between planning officers and developers on the scale of the project, we welcome more much-needed housing for the city and the fact this empty site will be put to good use."
