About 16 William Mews
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
16 William Mews is a mid-terrace house in Westminster, London, London (SW1X 9HF). It has a recorded floor area of 125 m² (around 1345 sq ft), construction records dating it to 1900-1929 and council tax band G. The latest certificate (June 2014) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from June 2014, so improvements made since then won't be reflected.
Today's modelled estimate of £2,247,000 is 40.9% below the 2021 sale of £3,800,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£2,824/sq ft) was about 306.6% above the typical sold price in the postcode. At 125 m² it's 20.8% larger than the typical home in the postcode (104 m² median across 16 EPCs). Sold June 2021 for £3,800,000.
