Flat 4 is a mid-terrace house in Trowbridge (BA14 0AQ). It has a recorded floor area of 37 m² (around 395 sq ft), construction records dating it to before 1900 and council tax band A. At 37 m² this is the 4th smallest of 9 units on EPC record in the building, where floor areas span 25–81 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (November 2008) shows an E (score 43), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 68). Main heating runs on electricity. The latest certificate is from November 2008, 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 37 m² it sits well below the postcode median (102 m² across 46 EPCs), making it one of the more compact homes locally. Today's modelled estimate of £108,000 is 20% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£228/sq ft) was about 17.8% above the typical sold price in the postcode.
