About 16a
16a is a three-bedroom semi-detached house in Islington, London, London (N7 9RD). It has a recorded floor area of 140 m² (around 1507 sq ft) and construction records dating it to before 1900. The latest certificate (February 2024) shows a C (score 79), near the top of the C band. The rating has held steady at C across 2 certificates since February 2014. Between certificates, lighting went from Average to Very Good.
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. At 140 m² the property is well over the postcode median (62 m² across 49 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £1,165,000 sits 58.5% above the 2008 sale of £735,000. One planning record on file: tree works approved in 2021. Past consents include tree works, meaningful when judging how the property has evolved.
