About This Property
This semi-detached house is located in UXBRIDGE, UB10 9BD. The property offers 93m² (1001 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (67/100), this property is around the UK average for energy efficiency.
