Get started16 Lowndes Square is a mid-terrace house in Westminster, London, London (SW1X 9HB). It has a recorded floor area of 264 m² (around 2845 sq ft) and construction records dating it to before 1900. The latest certificate (March 2009) shows a D (score 55), a step below the typical UK home. The recommended improvements would push it to C (score 71). The latest certificate is from March 2009, so improvements made since then won't be reflected.
At 264 m² the property is well over the postcode median (128 m² across 19 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £6,419,000 sits 84.7% above the 2021 sale of £3,475,000. On a £-per-square-foot basis, the last sale (£1,221/sq ft) was about 137.5% above the typical sold price in the postcode. 13 planning records sit against the property, 10 approved, 2 refused, 1 pending. Past consents include an extension, meaningful when judging how the property has evolved. An application is currently awaiting a decision. Last sale on file: £3,475,000 in January 2021. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
