Overview

About 3 Derwen Road

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

3 Derwen Road is a three-bedroom detached house in Ystradgynlais, Swansea, Swansea (SA9 1HL). It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (July 2014) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 83), a 3-band jump. The latest certificate is from July 2014, so improvements made since then won't be reflected.

At 96 m² it's 17.9% smaller than the typical home in the postcode (117 m² median across 5 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £260,000 sits 112.7% above the 2015 sale of £122,250. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 17.7% above the typical sold price in the postcode. Last sold in March 2015, so it's been off the market for around 11 years.
