1 Copperfields, Welwyn Garden City, AL7 2HH

1 Copperfields is a semi-detached house in Welwyn Garden City (AL7 2HH). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 1976-1982 and council tax band D. The latest certificate (April 2012) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from April 2012, so improvements made since then won't be reflected.

Held since June 1996 — that's 30 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 £363,000 sits 476.2% above the 1996 sale of £63,000. On a £-per-square-foot basis, the last sale (£74/sq ft) was about 76.5% below the postcode norm. One planning record on file: an extension approved in 2003. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
