A landmark office block in Edgbaston is set to be converted into flats.

Henderson Global Investors is planning to redevelop its 140,000 sq ft No 1 Hagley Road office tower - whose tenants include National Express - while a new 165,000 sq ft building is planned on the site of the building’s current car park – potentially to be used as a hotel. Henderson has submitted a planning application to convert the building into an apartment block, providing up to 182 flats. Four new penthouse floors will add a new skyline feature at the top.

Henderson has proposed a new building, up to 14 storeys high, to provide up to 165,000 sq ft of either hotel or student accommodation with scope for retail and leisure uses on the ground floor.

Martin Payne, fund manager at Henderson Global Investors, said: “Although No 1 Hagley Road continues to provide economical office accommodation for current and potential tenants through a flexible leasing structure, we are aware of the changing needs of the business community and the local area. We want to ensure that the building will continue to be utilised to its best potential for many years to come.

“The proposals will not only give a viable long-term use to the building, but also generate the ability to greatly enhance the external appearance of this major landmark which sits in one of the key gateways to the city centre.”

Associated Architects are behind the designs for the scheme.
