281a is a detached house in Hersham, Walton-On-Thames, Walton On Thames (KT12 5PZ). It has a recorded floor area of 16 m² (around 172 sq ft) and construction records dating it to 2012 onwards. At 16 m² this is the smallest unit on EPC record across the building (16–212 m²). The building's EPC ratings span F to B across 20 units on file. The latest certificate (July 2022) shows a C (score 70). Main heating runs on electricity.

It hasn't traded since September 2007, a hold of 19 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. At 16 m² it sits well below the postcode median (99 m² across 19 EPCs), making it one of the more compact homes locally. On a £-per-square-foot basis, the last sale (£1,626/sq ft) was about 354.4% above the typical sold price in the postcode. One planning record on file: an extension refused in 2019.
