About Flat 1
Flat 1 is an end-of-terrace house in Monmouth (NP25 3DF). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (August 2013) shows a D (score 58), a step below the typical UK home. When first surveyed in March 2009 the rating was F, the property has climbed 2 bands since. Between certificates, hot-water efficiency went from Very Poor to Good, lighting went from Very Poor to Very Good and main heating went from Poor to Good; while roof efficiency dropped from Average to Very Poor. The latest certificate is from August 2013, so improvements made since then won't be reflected. At 40 m² this is the 3rd smallest of 8 units on EPC record in the building, where floor areas span 25–64 m². The building's EPC ratings span E to C across 8 units on file.
Untraded for 16 years, with the last transfer in November 2010. One planning record on file: an extension approved in 2022. Past consents include an extension, meaningful when judging how the property has evolved. Today's modelled estimate of £150,000 is 42.9% above the 2010 sale price. On a £-per-square-foot basis, the last sale (£244/sq ft) was about 53.6% above the typical sold price in the postcode.
