Castlemartin Builders Ltd is a local building company based in Ingleby Barwick. Allan Ryder is the director of Castlemartin Builders Ltd and has over 30 years building experience. Allan started working with a building company after leaving school where quality and tidiness on the job was always a priority. He eventually left to form his own one man business and they were his work ethics throughout. He has built on that and gone from strength to strength before establishing Castlemartin Builders Ltd with several employees.
