16 Berthwin Street, Cardiff, CF11 9JH

16 Berthwin Street is a two-bedroom mid-terrace house in Cardiff (CF11 9JH). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to before 1900 and council tax band D. At 77 m² this is the 2nd smallest of 12 units on EPC record in the building, where floor areas span 63–198 m². The building's EPC ratings span F to C across 12 units on file. The latest certificate (February 2017) shows a D (score 62), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 75).

It hasn't traded since February 2008, a hold of 18 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. Today's modelled estimate of £186,000 sits 894.7% above the 2008 sale of £18,700. On a £-per-square-foot basis, the last sale (£23/sq ft) was about 89.8% below the postcode norm. At 77 m² it sits well below the postcode median (147 m² across 11 EPCs), making it one of the more compact homes locally.
