3 Aston House is a two-bedroom semi-detached house in Knotty Green, Beaconsfield, Beaconsfield (HP9 2TS). It has a recorded floor area of 90 m² (around 969 sq ft), construction records dating it to 2003-2006 and council tax band F. At 90 m² this is the 2nd smallest of 6 units on EPC record in the building, where floor areas span 89–159 m². The building's EPC ratings span C to B, with this unit at the bottom. On EPC score it ranks last in the building (70 versus a best of 82). The latest certificate (September 2023) shows a C (score 70).
It hasn't traded since December 2007, 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 90 m² it sits well below the postcode median (144 m² across 14 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). 5 planning records sit against the property, 0 approved, 3 refused. Across 2006–2007, sale prices here grew -0.1% per year, broadly in step with England's 0% HPI growth. Today's modelled estimate of £539,000 is 19.9% above the 2007 sale price.
