About 15 High Street
15 High Street is a three-bedroom mid-terrace house in Seal, Sevenoaks, Sevenoaks (TN15 0AL). It has a recorded floor area of 113 m² (around 1216 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (February 2016) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from February 2016, so improvements made since then won't be reflected. Period features are noted in the property record. The home occupies a cul-de-sac position.
At 113 m² the property is well over the postcode median (54 m² across 8 EPCs), placing it in the larger end of the local stock. One planning record on file: new windows approved in 2016. Past consents include new windows, meaningful when judging how the property has evolved. Across 2002–2016, sale prices on this property compounded at 5.2% per year. Today's modelled estimate of £558,000 is 15.1% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£399/sq ft) was about 71% above the typical sold price in the postcode. Last sold in June 2016, so it's been off the market for around 10 years.
