The Walbrook construction is occupying 1.6 acres of land which will eventually become a mixed use office and retail development in London’s city centre. When complete, The Walbrook will provide a gross area of 600,000 sq.ft, including 410,000 sq.ft of Grade A net letable area and 35,000 sq.ft of retail and restaurant accommodation. But it is not the project’s scale which makes it remarkable, rather the materials used.
