29 Margam Avenue, Southampton, SO19 2QL

29 Margam Avenue is a one-bedroom semi-detached house in Southampton (SO19 2QL). It has a recorded floor area of 34 m² (around 366 sq ft), construction records dating it to 1930-1949 and council tax band C. At 34 m² this is the smallest unit on EPC record across the building (34–133 m²). The building's EPC ratings span F to C, with this unit at the top. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (July 2013) shows a C (score 72). When first surveyed in February 2011 the rating was D, the property has climbed 1 band since. Between certificates, roof efficiency went from Average to Good, hot-water efficiency went from Average to Good and lighting went from Good to Very Good. The latest certificate is from July 2013, so improvements made since then won't be reflected.

At 34 m² it sits well below the postcode median (92 m² across 11 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 82% of similar EPCs). One planning record on file: an extension approved in 2015. Past consents include an extension, meaningful when judging how the property has evolved. Across 1998–2012, sale prices on this property compounded at 5.9% per year.
