35a is a two-bedroom mid-terrace house in Northampton (NN1 4NW). It has a recorded floor area of 42 m² (around 452 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (June 2019) shows a D (score 57), a step below the typical UK home. When first surveyed in September 2013 the rating was G, the property has climbed 3 bands since. Between certificates, roof efficiency went from Very Poor to Very Good and window efficiency went from Very Poor to Average. The recommended improvements would push it to C (score 70). Main heating runs on electricity. At 42 m² this is the 3rd smallest of 26 units on EPC record in the building, where floor areas span 39–164 m². The building's EPC ratings span E to C across 26 units on file.

It hasn't traded since January 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 42 m² it sits well below the postcode median (83 m² across 25 EPCs), making it one of the more compact homes locally. On a £-per-square-foot basis, the last sale (£276/sq ft) was about 107.6% above the typical sold price in the postcode.
