Key Information
  • Project Name: The Crosspoint
  • Client: Amsprop
  • Architect: Rolfe Judd
  • Main Contractor: ISG
  • Stone Contractor: Putney & Wood Ltd
  • Stone Used: Belgian Blue Limestone
  • Completed: March 2017

Owned by Amsprop, Alan Sugar’s Property development business, the re-development of Alderman’s House into ‘Crosspoint’ in the City of London, has created 41,000 sq ft of Grade ‘A’ BREEAM ‘excellent’  office space.

Rolfe Judd decided to use Belgian Blue limestone for the plinth rather than black granite imported from Asia or Africa. With a porosity of just 0.36% and density of 2.7kg/m3, Belgian stone is also known as ‘Petit Granite’ because it’s performance is similar to most granites.

Two additional benefits of Rolfe Judd specifying Belgian Blue instead of black granite are:

1. Lower Carbon Footprint

The Belgian Blue quarry is just 228miles from the site in Liverpool Street. This is just 75 miles further than the Portland stone used directly above it, and 75 miles closer than the Cumbrian red sandstone quarry used extensively on the upper floors.

2. Anti-Slavery Compliance

The subcontractor sourced the Belgian Blue limestone directly from the quarry. With such a direct supply chain the project team were certain that no bonded or child labour was involved anywhere in the quarrying, manufacturing or transportation of the Belgian Blue stone. With Belgium being part of the E.U. and therefore subject to the same EU-wide labour laws regulating working conditions as here in the U.K., both the client and the project team are further assured that by using Belgian Blue stone rather than black granite, their Anti-Slavery policies would not be compromised.

We were extremely happy with the quick efficient manufacture and delivery of the Belgian Blue, the installed stone looks fantastic.
