Get started12 Markham Street is a five-bedroom mid-terrace house in Kensington And Chelsea, London, London (SW3 3NP). It has a recorded floor area of 145 m² (around 1561 sq ft), construction records dating it to 1900-1929 and council tax band H. The latest certificate (June 2019) shows a C (score 70).
Untraded for 19 years, with the last transfer in January 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £3,350,000 sits 104.5% above the 2007 sale of £1,638,000. On a £-per-square-foot basis, the last sale (£1,049/sq ft) was about 26.9% above the typical sold price in the postcode. One planning record on file: an extension approved in 2007. Past consents include an extension, a basement excavation, a conservatory and new windows, meaningful when judging how the property has evolved. Its energy rating outperforms most of the postcode (better than 82% of similar EPCs).
Planning history includes recorded demolition works, indicating a major rebuild phase at this address.
