The conversion of the deconsecrated Christ Church in Marylebone, London NW1 into a multi purpose sports centre. The Grade II* listed building has been extensively reconfigured to house the headquarters of the Greenhouse Sports charity. It accommodates volleyball and judo but is primarily used for table tennis coaching and tournaments. Preservation of important ecclesiastical features and adaptation of existing fabric to provide appropriate and compliant playing, changing and access facilities has been achieved by thorough negotiations with Historic England.
