About 11 New Road
11 New Road is a four-bedroom detached house in Welwyn (AL6 0AE). It has a recorded floor area of 132 m² (around 1421 sq ft), construction records dating it to 1950-1966 and council tax band G. The latest certificate (September 2012) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 79), a 2-band jump. The latest certificate is from September 2012, so improvements made since then won't be reflected. Period features are noted in the property record. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility.
At 132 m² it's 28.3% smaller than the typical home in the postcode (184 m² median across 11 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). Across 1998–2022, sale prices on this property compounded at 4.9% per year. Today's modelled estimate of £1,016,000 is 18.1% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£605/sq ft) was about 65.1% above the typical sold price in the postcode. Sold February 2022 for £860,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One historical planning record sits against the property in 2026.
