A college in Glasgow is to be replaced with a £50million campus on the same site.

But the move will mean thousands of students and staff at Anniesland College in the West End working on a building site for the next three years.

The present college in Hatfield Drive, which has around 300 staff and up to 10,000 students each year, was built in the 1960s.

Deputy principal Brian Hughes said: "The buildings are in poor condition pretty much throughout and we suffer from water ingress.

"In preparing our business case we had to demonstrate the buildings needed to be replaced and not just re-clad.

"The new college will make a big difference to staff, students and the local community."

College bosses initially wanted to move the students to another building while work was going on but found it impossible to find a suitable site.

It is hoped work will start this summer with the first phase of work - the teaching block - being ready around January or February 2009.

When it is completed, students and staff will move in, allowing the other buildings on the site to be demolished.

More than 60 people objected to elements of the new college, with many unhappy the main building will be constructed on the highest point of the site.

Former Jordanhill councillor Christopher Mason told the planning committee: "The community council has no complaint about the effort Anniesland College has put into consulting the community. "But the issue which has not been resolved is the issue of building a four-storey building on Hatfield Drive.

"The biggest building should be in the centre of the site where it is now."

But a planning official said: "The reason why the new building cannot stay on its present site is because the new college has to be built while the existing college is on-site."
