Features @11Cavendishsq / Built in the reign of George III, No.11 Cavendish Square is a Grade II listed townhouse. Over the years the venue has been sympathetically extended to cater for larger events. While the rooms of the historical part of the house retain many of their original features and have beautiful proportions the modern rooms and meeting spaces offer the most up to date facilities that any event organiser would demand. / by No.11 Cavendish Square
