Get started18 Cwm Silyn is a semi-detached house in Caernarfon (LL55 2AG). It has a recorded floor area of 105 m² (around 1130 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (September 2014) shows a C (score 69), just inside the C band. The recommended improvements would push it to B (score 84). The latest certificate is from September 2014, so improvements made since then won't be reflected.
It hasn't traded since January 1996, a hold of 30 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £198,000 sits 361.5% above the 1996 sale of £42,900. On a £-per-square-foot basis, the last sale (£38/sq ft) was about 78.2% below the postcode norm. One planning record on file: an extension approved in 2016. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved. At 105 m² it's 21.6% larger than the typical home in the postcode (86 m² median across 7 EPCs).
18 Cwm Silyn's EPC is over a decade old — improvements since won't be reflected.
