Flat 3a, 26 Sussex Street, London, SW1V 4RL

Flat 3a is an end-of-terrace house in London (SW1V 4RL). It has a recorded floor area of 8 m² (around 86 sq ft), construction records dating it to 1900-1929 and council tax band E. At 8 m² this is the smallest unit on EPC record across the building (8–86 m²). The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (58 versus a best of 69). The latest certificate (December 2021) shows a D (score 58), a step below the typical UK home. When first surveyed in August 2010 the rating was E, the property has climbed 1 band since. Between certificates, window efficiency went from Very Poor to Poor. The recommended improvements would push it to C (score 79). Main heating runs on to be used only when there is no heating/hot.

Today's modelled estimate of £120,000 is 57.9% below the 2017 sale of £285,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£3,310/sq ft) was about 575.3% above the typical sold price in the postcode. At 8 m² it sits well below the postcode median (53 m² across 6 EPCs), making it one of the more compact homes locally. Last changed hands 9 years ago, in September 2017. One planning record on file: an extension refused in 2014.
