About 21 Avon Close
21 Avon Close is a semi-detached house in Watford (WD25 0DN). It has a recorded floor area of 68 m² (around 732 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (March 2019) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 84), a 3-band jump.
It hasn't traded since November 2007, a hold of 19 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. Today's modelled estimate of £474,000 sits 89.6% above the 2007 sale of £250,000. On a £-per-square-foot basis, the last sale (£342/sq ft) was about 25% above the typical sold price in the postcode. At 68 m² it's 18.8% larger than the typical home in the postcode (57 m² median across 24 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
