Flat 3 is a mid-terrace house in Sheffield (S10 3BZ). It has a recorded floor area of 35 m² (around 377 sq ft), construction records dating it to 1900-1929 and council tax band A. At 35 m² this is the 2nd smallest of 7 units on EPC record in the building, where floor areas span 31–49 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 (45 versus a best of 65). The latest certificate (June 2017) shows an E (score 45), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 80), a 2-band jump. Main heating runs on electricity.

It hasn't traded since April 2007, a hold of 19 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 35 m² it's 16.7% smaller than the typical home in the postcode (42 m² median across 49 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). Today's modelled estimate of £435,000 is 14.5% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£1,009/sq ft) was about 481.8% above the typical sold price in the postcode.
