About 29a
29a is a three-bedroom mid-terrace house in Thame (OX9 3EX). It has a recorded floor area of 179 m² (around 1927 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (December 2019) shows an E (score 48), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since December 2009. Between certificates, lighting went from Average to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would lift it to C (score 73), a 2-band jump.
It hasn't traded since February 1995, a hold of 31 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 179 m² the property is well over the postcode median (63 m² across 12 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs). Today's modelled estimate of £551,000 sits 437.6% above the 1995 sale of £102,500. On a £-per-square-foot basis, the last sale (£53/sq ft) was about 81.3% below the postcode norm.
