About 21a
21a is a detached house in Poole (BH15 4DW). It has a recorded floor area of 94 m² (around 1012 sq ft) and construction records dating it to 1930-1949. The latest certificate (July 2012) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 83), a 3-band jump. The latest certificate is from July 2012, 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. At 94 m² it sits well below the postcode median (167 m² across 22 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. 3 planning records sit against the property, 1 approved, 2 refused. Past consents include tree works, meaningful when judging how the property has evolved. Today's modelled estimate of £594,000 is 27.7% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£460/sq ft) was about 76.7% above the typical sold price in the postcode.
