About 30 Heol Y Castell
30 Heol Y Castell is a three-bedroom semi-detached house in Ely, Cardiff, Cardiff (CF5 5LS). It has a recorded floor area of 88 m² (around 944 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (December 2009) shows a C (score 70). The rating has held steady at C across 3 certificates since July 2009. Between certificates, lighting went from Good to Very Good. The latest certificate is from December 2009, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
Held since November 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. Today's modelled estimate of £170,000 sits 74.4% above the 2009 sale of £97,500. On a £-per-square-foot basis, the last sale (£103/sq ft) was about 30.8% below the postcode norm.
