About 1 Maldwyn Street
1 Maldwyn Street is an end-of-terrace house in Cardiff (CF11 9JR). It has a recorded floor area of 54 m² (around 581 sq ft) and construction records dating it to 1900-1929. At 54 m² this is the 3rd smallest of 14 units on EPC record in the building, where floor areas span 48–140 m². The building's EPC ratings span D to C, with this unit at the bottom.

The recommended improvements would push it to C (score 71). The latest certificate is from April 2011, so improvements made since then won't be reflected.
