About Afallon
Afallon is a detached house in Aberystwyth (SY23 1EW). It has a recorded floor area of 230 m² (around 2476 sq ft), construction records dating it to before 1900 and council tax band F. The latest certificate (January 2023) shows a D (score 58), a step below the typical UK home. The rating has held steady at D across 2 certificates since October 2012. Between certificates, lighting went from Good to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 78).
It hasn't traded since November 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 230 m² the property is well over the postcode median (176 m² across 11 EPCs), placing it in the larger end of the local stock. Across 2007–2007, sale prices on this property compounded at -54% per year. Today's modelled estimate of £323,000 sits 90% above the 2007 sale of £170,043. On a £-per-square-foot basis, the last sale (£69/sq ft) was about 51.6% below the postcode norm. One historical planning record sits against the property in 2010.
