Overview

About 1 Belsize Square

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

1 Belsize Square is a two-bedroom semi-detached house in Camden, London, London (NW3 4HT). It has a recorded floor area of 449 m² (around 4836 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (September 2009) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 56). The latest certificate is from September 2009, so improvements made since then won't be reflected.

It hasn't traded since December 2009, a hold of 16 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 449 m² the property is well over the postcode median (94 m² across 74 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). Across 1998–2009, sale prices on this property compounded at 27.2% per year. Today's modelled estimate of £6,331,000 is 26.6% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£1,034/sq ft) was about 74.6% above the typical sold price in the postcode. 3 planning records sit against the property, 2 approved, 1 refused.
