90a, Green Road, Bournemouth, BH9 1EB

90a is a four-bedroom detached house in Bournemouth (BH9 1EB). It has a recorded floor area of 46 m² (around 495 sq ft) and construction records dating it to 1900-1929. At 46 m² this is the smallest unit on EPC record across the building (46–161 m²). The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (May 2015) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from May 2015, so improvements made since then won't be reflected.

It hasn't traded since February 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. At 46 m² it sits well below the postcode median (99 m² across 9 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs). Across 2002–2008, sale prices on this property compounded at 8.1% per year. Today's modelled estimate of £162,000 is 20.9% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£271/sq ft) was about 217.1% above the typical sold price in the postcode.
