About 3 Heol Y Parc
3 Heol Y Parc is a semi-detached house in Cefneithin, Llanelli, Llanelli (SA14 7DE). It has a recorded floor area of 135 m² (around 1452 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (August 2009) shows a D (score 61), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 70). Main heating runs on oil. The latest certificate is from August 2009, so improvements made since then won't be reflected.
It hasn't traded since December 2009, a hold of 16 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 135 m² the property is well over the postcode median (96 m² across 31 EPCs), placing it in the larger end of the local stock.
