21 Baird Avenue, Upton, Northampton, NN5 4AD

21 Baird Avenue is a detached house in Upton, Northampton, Northampton (NN5 4AD). It has a recorded floor area of 238 m² (around 2562 sq ft), construction records dating it to 1991-1995 and council tax band E. The latest certificate (April 2015) shows a D (score 64), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since May 2014. Between certificates, roof efficiency went from Average to Good and lighting went from Poor to Very Good; while wall efficiency dropped from Good to Very Poor. The recommended improvements would lift it to B (score 82), a 2-band jump. The latest certificate is from April 2015, so improvements made since then won't be reflected.

Held since August 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. At 238 m² the property is well over the postcode median (108 m² across 8 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £508,000 sits 361.8% above the 1996 sale of £109,999. On a £-per-square-foot basis, the last sale (£43/sq ft) was about 61.3% below the postcode norm. One planning record on file: an extension approved in 2002. Past consents include an extension, meaningful when judging how the property has evolved.
