About Oast Dene
Oast Dene is a detached house in Ightham, Sevenoaks, Sevenoaks (TN15 9BD). It has a recorded floor area of 178 m² (around 1916 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (April 2016) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76). The latest certificate is from April 2016, so improvements made since then won't be reflected.
Today's modelled estimate of £884,000 is 34.5% below the 2021 sale of £1,350,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£705/sq ft) was about 74.4% above the typical sold price in the postcode. At 178 m² the property is well over the postcode median (109 m² across 9 EPCs), placing it in the larger end of the local stock. Last sale on file: £1,350,000 in August 2021. 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 2001.
