Overview

About 12a

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

12a is an end-of-terrace house in St. Mellons, Cardiff, Cardiff (CF3 0SD). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1991-1995 and council tax band C. The latest certificate (August 2016) 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 August 2016, so improvements made since then won't be reflected.

Held since March 2001 — that's 25 years off the open market, well above the local norm. 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 £210,000 sits 312.6% above the 2001 sale of £50,900. On a £-per-square-foot basis, the last sale (£75/sq ft) was about 55.5% below the postcode norm.
