About Newbolt House
Newbolt House is a detached house in Southwark, London, London (SE17 1AA). It has a recorded floor area of 58 m² (around 623 sq ft), construction records dating it to 1950-1966 and council tax band A. At 58 m² this is the 2nd smallest of 14 units on EPC record in Newbolt House, where floor areas span 54–86 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (April 2009) shows a C (score 71). The latest certificate is from April 2009, so improvements made since then won't be reflected.
It hasn't traded since September 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £345,000 sits 114.3% above the 2009 sale of £161,000. On a £-per-square-foot basis, the last sale (£258/sq ft) was about 17.3% below the postcode norm. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and new windows, meaningful when judging how the property has evolved. At 58 m² it's 17.3% smaller than the typical home in the postcode (70 m² median across 13 EPCs).
