Castlefied House is located on Liverpool Road between the Upper and Lower Campsfield Market buildings.  The companies who are attempting to let the building describe it as, follows: "Castlefield House is a landmark building which is currently undergoing an extensive refurbishment."

This was once the site of St. Matthew's Church.  It was designed by Sir Charles Barry, the architect responsible for the Mosley Street Art Gallery and the Athenaeum Club, in Manchester, and the Palace of Westminister in London.   The church was demolished in 1951.
