1a, Aylen Road, Portsmouth, PO3 5HB
About 1a
1a is a four-bedroom semi-detached house in Portsmouth (PO3 5HB). It has a recorded floor area of 137 m² (around 1475 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (January 2014) shows a C (score 71). When first surveyed in September 2013 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Poor to Good, hot-water efficiency went from Very Poor to Good and lighting went from Very Poor to Very Good. The recommended improvements would push it to B (score 83). The latest certificate is from January 2014, so improvements made since then won't be reflected.
At 137 m² the property is well over the postcode median (86 m² across 28 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 75% of similar EPCs). Today's modelled estimate of £342,000 sits 96% above the 2013 sale of £174,500. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 30.3% below the postcode norm. Last sold in November 2013, so it's been off the market for around 13 years. One historical planning record sits against the property in 2019.
