Get started20 Chesham Mews is a mid-terrace house in Guildford (GU1 3NL). It has a recorded floor area of 71 m² (around 764 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (November 2020) shows a C (score 71). The recommended improvements would push it to B (score 86).
At 71 m² the property is well over the postcode median (47 m² across 20 EPCs), placing it in the larger end of the local stock. 6 planning records sit against the property, 6 approved, 0 refused. Past consents include an extension, a loft conversion, a conservatory and tree works, meaningful when judging how the property has evolved. The record references conservation-area consent, which constrain future alterations. On a £-per-square-foot basis, the last sale (£556/sq ft) was about 40.3% above the typical sold price in the postcode. Sold June 2021 for £425,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
Planning history includes both a loft conversion and an extension — the classic family-home expansion.
