Westminster City Council is set to approve TP Bennett-designed proposals to redevelop a 1970s office building near Victoria Station, adding two storeys to its height and boosting floorspace by 80%.

The practice’s proposals for Gillingham House would deliver an eight-storey building with roof terraces and 9,532sq m of office space, as well as a 100sq m café. The current part-four, part-seven-storey building has 5,106sq m of office floorspace, and a 150sq m flat originally intended for a caretaker. TP Bennett’s proposals do not provide any residential accommodation.

Gillingham House, in Gillingham Street, was completed in 1975 and originally served as a depository for major banks until it was converted into office use.
