This project was awarded Award in the Interiors category at the Natural Stone Awards 2006.
The official guide said, 'Szerelemey sourced the specified stone for this project from Portugal, France, Belgium, Ital and Tunisia, as well as using English Portland limestone and Cornish and Scottish granite. Architects Dixon Jones were heavily involved in the choise of stones and historic marble specialists McMarmilloyd helped ensure the success of this prestigious project. The final selection and positioning of each individual stone within the walls was a painstaking task for the architects, with each area of cladding set out on a dry floor in Italy and viewed from a scaffold tower. Each stone was numbered so it could be correctly placed in the project.
The cladding was fixed to a galvanised steel structural framing system. Gialla Antico marble from Tunisia was used for the portico staircase, again following dry-setting selection in Italy. Belgian Black was used extensively for wall linings within the main portico foyer and lobbies. New staircases feature Azul Cascais treads each weighing 300kg and with a Belgian Black insert.
Szerelmey's work also included cleaning, repair and re-fixing of previouslt set aside historic marbles and supplying incised donor plaques that record the names of those who contributed to the cost of the project.'
The judges commented, 'An appropriately sophisticated addition to one of our much loved friends, the National Gallery.'
