    Series of investigative works to the North Block. The proposed investigative and opening up works comprise trial pits in third party walls at basement level, the careful removal of plaster in various locations to expose the structure behind, and other physical works to open up elements of the building where required to better inform the Stage 4 design elements within the existing structural context. The locations of the opening up works have been carefully selected to ensure minimal disruption on the historic fabric, and where possible, investigations and openings are proposed in areas of twentieth century construction.
