About 15 Cornwall Avenue

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

15 Cornwall Avenue is a four-bedroom mid-terrace house in Haringey, London, London (N22 7DA). It has a recorded floor area of 128 m² (around 1376 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (March 2009) shows an E (score 44), well below the UK norm with real room to improve. The latest certificate is from March 2009, so improvements made since then won't be reflected.

Held since July 2009 — that's 17 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. Today's modelled estimate of £902,000 sits 121.1% above the 2009 sale of £408,000. On a £-per-square-foot basis, the last sale (£297/sq ft) was about 23.9% below the postcode norm. At 128 m² it's 29.1% larger than the typical home in the postcode (99 m² median across 34 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). 2 planning records sit against the property, 0 approved, 1 refused.
