National Gallery – London
McMarmilloyd supplied all the marble for the restoration of the original entrance and stairway along with the marble for the creation of the new entrance and stairways.
Restoration involved the sourcing of Giallo Antico and Paonazzo to closely match the original stones. For the new entrance Noir St. Laurent, Azul Cascais, Noir Belge and other Limestones were used. The project won the Stone Federation award for RIBA Conservation in 2006.
