About 21 Deacons Hill Road
21 Deacons Hill Road is a three-bedroom semi-detached house in Elstree, Borehamwood, Borehamwood (WD6 3HY). It has a recorded floor area of 104 m² (around 1119 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (June 2014) shows an E (score 39), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 85), a 3-band jump. The latest certificate is from June 2014, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.
At 104 m² it sits well below the postcode median (193 m² across 7 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. Today's modelled estimate of £798,000 is 28.7% above the 2014 sale price. On a £-per-square-foot basis, the last sale (£554/sq ft) was about 39% above the typical sold price in the postcode. Last sold in December 2014, so it's been off the market for around 11 years.
