About 7 Derwen Fawr
7 Derwen Fawr is a three-bedroom detached house in Llandybie, Ammanford, Ammanford (SA18 2UY). It has a recorded floor area of 80 m² (around 863 sq ft), construction records dating it to 1983-1990 and council tax band D. The property has solar panels on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a conservatory. The latest certificate (March 2011) shows a C (score 69), just inside the C band. The latest certificate is from March 2011, so improvements made since then won't be reflected.
Untraded for 18 years, with the last transfer in April 2008. Across the public record there are 4 sales, relatively high churn for a single property.

Across 1995–2008, sale prices on this property compounded at 7.6% per year. Today's modelled estimate of £235,000 sits 56.7% above the 2008 sale of £150,000. One planning record on file: an extension approved in 2022. Past consents include an extension, meaningful when judging how the property has evolved.
