1-4 Marble Arch

We have been working alongside Galliford Try following their appointment by The Portman Estate to deliver the new Allford Hall Monaghan Morris designed, £55m rebuild of this historic building.
Using the steel Jansen VISS SG (structural glazing) system the project has seen the existing façade retained, while behind it a full demolition and rebuild has taken place, creating three floors of retail space and a further seven floors of high quality Category A offices.

The project, which is set to achieve a BREEAM Excellent rating, was designed by Allford Hall Monaghan Morris and saw the existing 1920s-built façade retained by means of a complex framework, followed by ‘top down’, floor-by-floor demolition.
In place of the old internal structure a new structural steel frame, rising from the sub-basement to the roof contains 123,766 sqft of space over 11 storeys, including three floors for retail areas and seven floors of commercial office space.
