11 Ffordd Donaldson, Copper Quarter, Pentrechwyth, Swansea, SA1 7FJ

11 Ffordd Donaldson is a detached house in Pentrechwyth, Swansea, Swansea (SA1 7FJ). It has a recorded floor area of 4 m² (around 47 sq ft) and council tax band D. At 4 m² this is the smallest unit on EPC record across the building (4–107 m²). The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (March 2009) shows a C (score 78), near the top of the C band. The latest certificate is from March 2009, so improvements made since then won't be reflected.

Today's modelled estimate of £11,000 is 91.3% below the 2009 sale of £126,500, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£2,683/sq ft) was about 1657% above the typical sold price in the postcode. Held since June 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 4 m² it sits well below the postcode median (105 m² across 13 EPCs), making it one of the more compact homes locally.
