The site includes two scheduled ancient monuments and several grade 1 and grade II* listed buildings, and is within a conservation area. The processes for securing the necessary consents were complex with the City and County Councils and English Heritage all having separate statutory responsibilities. The attitude of the planning and conservation officers was initially cautious, for very good reasons, but as they were consulted throughout the design and development a "consents group" began to form. The Consents Group met regularly with the project managers, architects and engineers to discuss the plans thereby ensuring effective cooperation and avoiding disputes and delay. This was helped by the Conservation Plan which defined the principles of conservation across the site.
