The Grade I National Gallery was constructed at Parliament’s request to house the Nations art collection. This impressive classically styled stone building was constructed between 1832-1838 to the design of William Wilkins and commands a striking position on the North side of Trafalgar Square.

Paye worked closely with the National Gallery under the direction of Purcell Architects to carry out an area of sample repair works. Trials included the replacement and improvement of the lead capping to the parapet & cornice, as well as Portland stone indents to the string course and replacement of the bird deterrent system to the window sills and cornice’s. Further to these restoration works, specialist conservation techniques were also employed to include Doff cleaning, laser cleaning trails and the completion of mortar repairs and repointing.

These trials were completed to help inform a larger scale project at a later phase.
