1d, Upsdell Avenue, Enfield, London, N13 6JP

1d is a five-bedroom end-of-terrace house in Enfield, London, London (N13 6JP). It has a recorded floor area of 72 m² (around 777 sq ft), construction records dating it to 1930-1949 and council tax band E. At 72 m² this is the 3rd smallest of 18 units on EPC record in the building, where floor areas span 46–205 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (May 2010) shows a C (score 72). When first surveyed in October 2008 the rating was D, the property has climbed 1 band since. Between certificates, roof efficiency went from Poor to Average and window efficiency went from Poor to Good; while wall efficiency dropped from Good to Very Poor and lighting dropped from Very Good to Poor. The latest certificate is from May 2010, so improvements made since then won't be reflected.

It hasn't traded since July 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. 3 planning records sit against the property, 2 approved, 1 refused. Past consents include an extension, a porch and subdivision, meaningful when judging how the property has evolved. At 72 m² it's 22.4% smaller than the typical home in the postcode (93 m² median across 22 EPCs). Its energy rating outperforms most of the postcode (better than 77% of similar EPCs). Today's modelled estimate of £615,000 is 39.8% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£566/sq ft) was about 32% above the typical sold price in the postcode.
