PLANS to create a what critics have branded a “glorified greenhouse” on a bar’s rooftop terrace within sight of a city’s cathedral and castle have been approved.

Durham county councillors yesterday granted permission to Revolution Bars to make changes to the former Bishop Langley pub, on the banks of the River Wear, next to Framwelgate Bridge.

The chain, which wants to open new premises in the city, said to make the venture viable it needs to put a retractable roof on the terrace so it can be used throughout the year.

But because the venue is in sight of Durham’s World Heritage Site (WHS), concerns were raised about the suitability of the roof.

WHS coordinator Jane Gibson said the roof would interrupt views from Framwelgate Bridge to the castle and cathedral while the The City of Durham Trust added its voice to objections, disagreeing with Revolution’s claim that the roof will enhance the setting of the bridge.

Objecting to the plans, Councillor David Freeman said: “This application is, it may seem harsh, but it seems to me to be little more than a glorified greenhouse - a very large greenhouse they are putting on top of an empty pub building.

“It doesn’t seem a very sturdy structure or a particularly attractive sight within site of the World Heritage Site over the river. I am concerned that the roof comes, off because that would spread more noise.”

Mark Shearman, speaking on behalf of Revolution at an area planning committee meeting, said the “modest glazed structure”would improve the appearance of the “cluttered” roof terrace and enhance the views towards the cathedral while enclosing any noise.

He added: “Revolution will be investing £1m in transforming this site and would be committing to a 25-year lease, thereby securing its long-term viable use. They will also be creating 50 to 60 full and part-time jobs.”

Durham County Council planning officer Paul Hopper recommended that the scheme be approved saying Historic England and the council’s design and conservation section had raised no objections. He added, the development would have a “less than substantial” impact on thee heritage sites and will help bring the venue, which has been empty for more than a year, back into use.
