Caswell House, Flat 35, The Crescent, Llandaff, Cardiff, CF5 2DL

Caswell House is a two-bedroom mid-terrace house in Llandaff, Cardiff, Cardiff (CF5 2DL). It has a recorded floor area of 67 m² (around 726 sq ft), construction records dating it to 1950-1966 and council tax band E. At 67 m² this is the 4th smallest of 7 units on EPC record in Caswell House, where floor areas span 35–80 m². The building's EPC ratings span D to C, with this unit at the bottom. Other recorded features include a balcony. The latest certificate (July 2009) shows a D (score 67), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 80). The latest certificate is from July 2009, so improvements made since then won't be reflected.

Held since October 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. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs). Across 2006–2009, sale prices on this property compounded at -0.9% per year. Today's modelled estimate of £174,000 is 24.3% above the 2009 sale price.
