Clegg Construction has been awarded the contract to redevelop and refurbish 21 Queen Street in Leeds.
The contractor will add two new floors to the existing building, formerly known as Prince William House, to create a total of 37,500 sq ft of Grade A office space.
Developer Formal Investments said the building would feature sustainable credentials, flexible floor plates and a glass front elevation to give a sense of space and light.
Formal Investments said it is investing £4m to transform the office building.
Clegg Construction business development manager John Dixon said: “21 Queen Street highlights a confidence in the future of Leeds office space. After years of little or no speculative commercial development, it is great to see the new belief in the city.”
Joint letting agent Jonathan Shires of CBRE said: “With the shortage of quality Grade A alternatives offering modern efficient floor plates within Leeds’ traditional core, we are anticipating high demand for the space.”
Work is due to be completed in August.
Formal Investments also announced it has sold its building 2180 at Thorpe Park business park to Kier Property Investments. The space is currently leased to Northern Foods.
