Grade II listed building, cited as one of the 15 most important modern listed buildings in the UK.

Mountbatten House is a six-storey terraced commercial complex, originally commissioned by paper merchants Wiggins Teape. It was designed by Arup Associates’ Group 2 and constructed in 1974-76. IBM was a later occupant, and it is now Grade II Listed. Its unique concrete frame design is of particular interest, along with the spectacular landscaped terracing made possible by the sloping site.

Constructed using a combination of in situ and precast concrete, each floorplate includes a 1m deep void for building services installations — presenting design and logistical challenges for the adaptation works. We are providing quantity surveying and project management services for the building’s full refurbishment, which will result in flexible Grade A office space.
