About Flat 4
Flat 4 is a mid-terrace house in Towcester (NN12 6DQ). It has a recorded floor area of 23 m² (around 248 sq ft), construction records dating it to before 1900 and council tax band A. At 23 m² this is the smallest unit on EPC record across the building (23–56 m²). The building's EPC ratings span F to C, with this unit at the top. The latest certificate (November 2016) shows a C (score 76), near the top of the C band. When first surveyed in December 2008 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Very Poor to Poor, hot-water efficiency went from Very Poor to Very Good and lighting went from Very Poor to Good. The recommended improvements would push it to B (score 82).
2 planning records sit against the property, 1 approved, 1 refused. Past consents include new windows, meaningful when judging how the property has evolved. The record references listed-building consent, which constrain future alterations. At 23 m² it sits well below the postcode median (49 m² across 22 EPCs), making it one of the more compact homes locally. Its energy rating outperforms most of the postcode (better than 73% of similar EPCs). Today's modelled estimate of £118,000 is 15.7% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£412/sq ft) was about 80% above the typical sold price in the postcode. Most recent transfer: August 2022 at £102,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
