About 15 Brecon Close
15 Brecon Close is a three-bedroom detached house in Swindon (SN3 1JT). It has a recorded floor area of 160 m² (around 1722 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (July 2014) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since February 2010. Between certificates, window efficiency went from Very Poor to Good; while roof efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from July 2014, so improvements made since then won't be reflected.
It hasn't traded since June 2010, a hold of 16 years that's notably long for the area. At 160 m² the property is well over the postcode median (105 m² across 9 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £479,000 sits 75.8% above the 2010 sale of £272,500. On a £-per-square-foot basis, the last sale (£158/sq ft) was about 37.2% below the postcode norm. One planning record on file: an extension approved in 2010. Past consents include an extension, a garage conversion and a porch, meaningful when judging how the property has evolved.
