151a is an end-of-terrace house in Royston, Barnsley, Barnsley (S71 4BY). It has a recorded floor area of 29 m² (around 313 sq ft), construction records dating it to 1900-1929 and council tax band A. At 29 m² this is the 2nd smallest of 5 units on EPC record in the building, where floor areas span 22–93 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (September 2009) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 77). The latest certificate is from September 2009, so improvements made since then won't be reflected.

Held since November 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 29 m² it sits well below the postcode median (71 m² across 4 EPCs), making it one of the more compact homes locally. Across 2003–2009, sale prices on this property compounded at 30.2% per year.
