23 Garrett Court, Gertrude Road, Norwich, NR3 4SD

23 Garrett Court is a one-bedroom end-of-terrace house in Norwich (NR3 4SD). It has a recorded floor area of 43 m² (around 458 sq ft), construction records dating it to 1983-1990 and council tax band A. At 43 m² this is the 9th smallest of 36 units on EPC record in the building, where floor areas span 41–56 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (December 2009) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76). The latest certificate is from December 2009, so improvements made since then won't be reflected.

Held since March 2007 — that's 19 years off the open market, well above the local norm. 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 1997–2007, sale prices on this property compounded at 13.7% per year. Today's modelled estimate of £126,000 is 20.1% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£229/sq ft) was about 21.6% above the typical sold price in the postcode.
