About 1 Crowther Close
1 Crowther Close is a three-bedroom detached house in Southampton (SO19 1BX). It has a recorded floor area of 110 m² (around 1184 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (November 2020) shows a C (score 70). When first surveyed in January 2011 the rating was G, the property has climbed 4 bands since. Between certificates, wall efficiency went from Poor to Average, roof efficiency went from Very Poor to Good and hot-water efficiency went from Very Poor to Good; while window efficiency dropped from Good to Average. The recommended improvements would push it to B (score 82). It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The home occupies a cul-de-sac position.
At 110 m² the property is well over the postcode median (71 m² across 49 EPCs), placing it in the larger end of the local stock. One planning record on file: an extension approved in 2012. Past consents include an extension and a porch, meaningful when judging how the property has evolved. On a £-per-square-foot basis, the last sale (£308/sq ft) was about 60.1% above the typical sold price in the postcode. Last sale on file: £365,000 in September 2021. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
