Get started29 Astell Street is a four-bedroom mid-terrace house in Kensington And Chelsea, London, London (SW3 3RT). It has a recorded floor area of 136 m² (around 1464 sq ft), construction records dating it to 1967-1975 and council tax band H. The latest certificate (July 2020) shows a D (score 65), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 76).
Today's modelled estimate of £2,875,000 is 17.9% below the 2021 sale of £3,500,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£2,391/sq ft) was about 165.8% above the typical sold price in the postcode. At 136 m² it sits well below the postcode median (269 m² across 10 EPCs), making it one of the more compact homes locally. 13 planning records sit against the property, 5 approved, 3 refused. Past consents include an extension, a basement excavation and new windows, meaningful when judging how the property has evolved. Last sale on file: £3,500,000 in September 2021. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
A recent planning application at 29 Astell Street was refused — worth checking the council file.
