20 Helmsley Drive, Coundon, Bishop Auckland, DL14 8NX

20 Helmsley Drive is a three-bedroom semi-detached house in Coundon, Bishop Auckland, Bishop Auckland (DL14 8NX). It has a recorded floor area of 70 m² (around 753 sq ft), construction records dating it to 1991-1995 and council tax band B. The latest certificate (May 2014) shows a D (score 59), a step below the typical UK home. The rating has held steady at D across 2 certificates since April 2014. Between certificates, roof efficiency dropped from Good to Very Poor. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from May 2014, so improvements made since then won't be reflected. Other recorded features include a conservatory.

Held since May 1998 — that's 28 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 £153,000 sits 178.2% above the 1998 sale of £55,000. On a £-per-square-foot basis, the last sale (£73/sq ft) was about 33% below the postcode norm. One planning record on file: an extension approved in 2007. Past consents include an extension, meaningful when judging how the property has evolved.
