Paisley activists say they are seeking legal advice after planning permission was granted for more than 600 homes in a 150 million project at Dykebar.
Bellway Homes, Cala Homes and Barratt Homes were formally granted permission for their proposed Thornly Park village by the Scottish Government Reporter.
The national planning authority had earlier indicated it was minded to approve the development off Grahamston Road but has now published its final decision.
