About 21 Browning Avenue
21 Browning Avenue is a four-bedroom semi-detached house in Sutton (SM1 3QU). It has a recorded floor area of 118 m² (around 1270 sq ft), construction records dating it to 1950-1966 and council tax band E. The latest certificate (June 2021) shows a D (score 66), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since June 2011. Between certificates, lighting went from Good to Very Good; while roof efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 87), a 2-band jump. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility.
Most recent transfer: December 2021 at £675,000. Across the public record there are 5 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One planning record on file: an extension approved in 2013. Past consents include an extension, a garage conversion, a porch and a conservatory, meaningful when judging how the property has evolved. Across 1999–2021, sale prices on this property compounded at 6.9% per year. Today's modelled estimate of £773,000 is 14.5% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£531/sq ft) was about 55.4% above the typical sold price in the postcode.
