Get started18 Beech Grove is a three-bedroom semi-detached house in Owslebury, Winchester, Winchester (SO21 1LS). It has a recorded floor area of 76 m² (around 818 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (May 2016) shows a D (score 59), a step below the typical UK home. When first surveyed in February 2012 the rating was E, the property has climbed 1 band since. Between certificates, window efficiency went from Poor to Average and lighting went from Poor to Very Good; while roof efficiency dropped from Very Good to Good. The recommended improvements would lift it to B (score 87), a 2-band jump. Main heating runs on electricity. The latest certificate is from May 2016, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
2 planning records sit against the property, 1 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 76 m² it's 15.2% larger than the typical home in the postcode (66 m² median across 31 EPCs). Today's modelled estimate of £416,000 is 14% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£446/sq ft) was about 62.4% above the typical sold price in the postcode. Sold April 2022 for £365,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
