Lambeth Palace is a Grade I listed building and the National Heritage List describes it as a group of ecclesiastical, ceremonial, defensive and residential buildings of varying periods dating from the 13th Century through to the 19th Century.
The overall Master Plan redevelopment of the Palace involves a series of renovations throughout the palace and its gardens which will be carried out in phases and over several years. The works will entail internal and external refurbishment/alterations of the Palace and grounds, the residence of the Archbishop of Canterbury, which will be carried out in phases. Initially, the project will entail opening-up works to walls, floors and ceilings for enabling works involving: asbestos survey; lead paint survey; anthrax survey; archaeological investigations; internal trial pits; roof escape route works including hatches and walkway; and, services validations.
