British Land has appointed architects for the £160m redevelopment of the former NatWest building on Colmore Row in Birmingham.
Architects Hamiltons is working with British Land and will unveil the plans to the public at a week long exhibition starting tomorrow.
British Land bought the 280,000 sq ft building for £25m in January and will lodge a planning application later this year for a 28 storey building. It hopes planning permission will be granted in the spring.
The ground floor will include some retail and leisure units.
Robert Samuel, a director of British Land, said: ‘A great deal of work has gone into the sustainable design of the building. We want it to be a landmark not only in terms of its location and size, but also in terms of the quality of design and Green credentials.’
