About 12 Clos Penderri
12 Clos Penderri is a detached house in Penllergaer, Swansea, Swansea (SA4 9BZ). It has a recorded floor area of 136 m² (around 1465 sq ft), construction records dating it to 1976-1982 and council tax band F. The latest certificate (September 2010) shows a D (score 58), a step below the typical UK home. When first surveyed in June 2009 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Average and lighting went from Very Poor to Poor. The recommended improvements would push it to C (score 74). The latest certificate is from September 2010, so improvements made since then won't be reflected.
It hasn't traded since October 2000, a hold of 26 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £350,000 sits 218.2% above the 2000 sale of £110,000. On a £-per-square-foot basis, the last sale (£75/sq ft) was about 51.5% below the postcode norm. One planning record on file: an extension approved in 2018.
