Westminster Hall, Palace of Westminster
Built under the direction of William II (Rufus) in 1097, and subsequently remodelled during the reign of Richard II to include its present roof and massing, Westminster Hall is one of the oldest surviving buildings in London. Although interior modifications were made during the 18th and 19th centuries, a substantial amount of the medieval masonry, carved enrichments and polychromy remain intact. S uffering from centuries of pollution, moisture penetration and bombing during WWI, the historic fabric to the interior and exterior of Westminster Hall required extensive conservation and repair.
Donald Insall Associates was commissioned to undertake condition surveys of the interior masonry, timber roof structure, exterior roof abutments, and ornamental lead lantern. Following on from the surveys, the practice was appointed to lead a two year conservation programme for the interior to include masonry cleaning, conservation of the medieval and 19th century carvings, and introduction of a new lighting scheme that would better present the Hall and its magnificent timber roof to the public.
