The 2nd Earl travelled to England and was once again inspired by the sublime architecture of the country houses and towers he saw. He also brought home advice from L.N. Cottingham, an architect who would become one of the most important contributors to Adare Manor. Cottingham, like the 2nd Earl, was a member of the Oxford Society for Promoting the Study of Gothic Architecture. He was engaged to assist with the interior design of the new building, although he had never visited Adare. By 1840, Cottingham was an integral member of the design team.
