The intention is to create a landmark which will be a tourist attraction synonymous with the city of Bristol

Martin Pease, architect

He said: "This is a unique site on a major artery into the city.

"It is a natural focal point and a gateway to the south side of the city."

The skyscraper would straddle a listed building, the former George and Railway pub.

Its architects are considering "green" techniques, such as harvesting wind power from rooftop turbines and collecting rain water.

Combined with a scheme to use windows for air conditioning, Mr Pease believes the building could achieve zero energy consumption.

City landmark

About 1,500 people could be employed in the offices in Project 360 Degrees, while its apartments could become home to 500 residents.

At 150 metres (almost 500 feet) in height, the skyscraper would dwarf many of Bristol's apartment and office blocks.

Mr Pease said: "The intention is to create a landmark which will be a tourist attraction synonymous with the city of Bristol."
