 On a grand scale, the building comprises eleven bays and is constructed of red brick, with Bath stone dressings.The architect of the block is not known for certain but Newman follows Howard Colvin in suggesting the brothers, Roger and William Hurlbutt, who had worked in a similar style at Ragley Hall and Warwick Castle.The central carriage arch is framed by Corinthian columns and topped by a pediment with a clock dated 1766.
