About 115 Dinas Street
115 Dinas Street is a mid-terrace house in Plasmarl, Swansea, Swansea (SA6 8LL). It has a recorded floor area of 94 m² (around 1012 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (July 2026) shows a D (score 67), on the cusp of jumping into the C band. When first surveyed in January 2012 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Poor to Good, hot-water efficiency went from Poor to Good and lighting went from Average to Good. The recommended improvements would push it to C (score 78). This certificate was lodged in the last six months, so the rating reflects current condition.
Held since November 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 94 m² it's 16.8% larger than the typical home in the postcode (81 m² median across 18 EPCs). Today's modelled estimate of £121,000 is 38.3% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£86/sq ft) was about 15.7% above the typical sold price in the postcode.
