21 Osborne Road, Huddersfield, HD1 5HB

21 Osborne Road is a semi-detached house in Huddersfield (HD1 5HB). It has a recorded floor area of 84 m² (around 904 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (July 2014) shows an E (score 48), well below the UK norm with real room to improve. Earlier certificates rated it D (March 2014); the latest reading is one band lower. Between certificates, window efficiency went from Average to Good; while wall efficiency dropped from Good to Poor and lighting dropped from Very Good to Good. The recommended improvements would lift it to C (score 72), a 2-band jump. The latest certificate is from July 2014, so improvements made since then won't be reflected.

It hasn't traded since April 1996, a hold of 30 years that's notably long for the area. 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 £139,000 sits 275.7% above the 1996 sale of £37,000. On a £-per-square-foot basis, the last sale (£41/sq ft) was about 58.8% below the postcode norm. One historical planning record sits against the property in 2014. The record references conservation-area consent, which constrain future alterations. At 84 m² it sits well below the postcode median (120 m² across 25 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 72% of similar EPCs).
