About Flat
Flat is a two-bedroom mid-terrace house in Swansea (SA1 4HS). It has a recorded floor area of 70 m² (around 753 sq ft), construction records dating it to 1900-1929 and council tax band B. At 70 m² this is the smallest unit on EPC record across the building (70–159 m²). The building's EPC ratings span G to D, with this unit at the top.

Between certificates, lighting went from Average to Very Good; while roof efficiency dropped from Good to Very Poor.
It hasn't traded since March 2004, a hold of 22 years that's notably long for the area. Today's modelled estimate of £112,000 sits 460% above the 2004 sale of £20,000. On a £-per-square-foot basis, the last sale (£27/sq ft) was about 74.3% below the postcode norm.
