Flat 4, 28 St Johns Park, London, SE3 7JH

Flat 4 is a detached house in London (SE3 7JH). It has a recorded floor area of 71 m² (around 766 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (June 2009) shows an E (score 39), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 66). The latest certificate is from June 2009, so improvements made since then won't be reflected.

It hasn't traded since September 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. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Across 1998–2008, sale prices on this property compounded at 9.3% per year. Today's modelled estimate of £530,000 is 49.5% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£463/sq ft) was about 17.5% above the typical sold price in the postcode.
