At 76 m² the property is well over the postcode median (51 m² across 14 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement.

One planning record on file: an extension approved in 2004. Past consents include an extension, a basement excavation and a conservatory, meaningful when judging how the property has evolved.
