CONCERNS have been raised that a 'historic and unique' former pub - believed to be the only intact example of a 17th century coach house in Weymouth - has been altered without planning permission. As reported, owners of the former Swan Inn at number 567 Dorchester Road are seeking legal acknowledgement to legitimise changes to the building, in respect of planning laws which state enforcement action cannot be taken after a four-year period. The pub ceased trading around 2004 and changed hands two years later. Planning permission was granted for the Upwey Grade II listed building to be converted into a family home in 2007, but expired after works did not get under way.
