The top of a Norwich city centre office block, which has stood vacant for more than five years, could be turned into a restaurant.

Y Construction, the owners of Rose Lane Business Centre, had asked Norwich City Council for permission to change the use of the fifth floor of the building into a restaurant.

Officers at City Hall have given the proposal the go-ahead, with the restaurant open to the public between 7am and midnight.

The business centre, built in the early 1970s, was formerly used by Aviva, but has long stood empty.

But Y Construction is looking to breathe new life into the property.

It is rebranding the 70,000 square foot business centre as The Union Building, offering refurbished offices and studio space to let.

The developers have already got permission for a gym and nursery in the building.
