7 Longhirst, Killingworth, Newcastle Upon Tyne, NE12 5BG

7 Longhirst is a four-bedroom detached house in Killingworth, Newcastle Upon Tyne, Newcastle Upon Tyne (NE12 5BG). It has a recorded floor area of 123 m² (around 1324 sq ft), construction records dating it to 1996-2002 and council tax band D. The latest certificate (May 2014) shows a C (score 69), just inside the C band. The latest certificate is from May 2014, so improvements made since then won't be reflected. Other recorded features include a conservatory.

Held since December 2009 — that's 16 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. At 123 m² the property is well over the postcode median (88 m² across 7 EPCs), placing it in the larger end of the local stock. Across 1998–2009, sale prices on this property compounded at 7.5% per year. Today's modelled estimate of £306,000 sits 56.9% above the 2009 sale of £195,000. On a £-per-square-foot basis, the last sale (£147/sq ft) was about 19.5% below the postcode norm. One planning record on file: an extension approved in 2005. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
