Flat 1, 30 Street Lane, Leeds, LS8 2ET

Flat 1 is a one-bedroom semi-detached house in Leeds (LS8 2ET). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to 1900-1929 and council tax band C. At 40 m² this is the 2nd smallest of 4 units on EPC record in the building, where floor areas span 35–91 m². The building's EPC ratings span E to D, with this unit at the bottom. On EPC score it ranks last in the building (46 versus a best of 67). The latest certificate (January 2014) shows an E (score 46), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from January 2014, so improvements made since then won't be reflected.

Held since July 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 40 m² it sits well below the postcode median (86 m² across 34 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs). Across 1999–2007, sale prices on this property compounded at 10.3% per year. Today's modelled estimate of £170,000 is 26.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£311/sq ft) was about 70% above the typical sold price in the postcode.
