About 3d
3d is a mid-terrace house in Camden, London, London (NW3 6AL). It has a recorded floor area of 53 m² (around 570 sq ft) and construction records dating it to 1900-1929. At 53 m² this is the 3rd smallest of 18 units on EPC record in the building, where floor areas span 46–177 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (June 2019) shows a C (score 74). The rating has held steady at C across 4 certificates since April 2009. Between certificates, lighting went from Very Poor to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good.
It hasn't traded since November 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 £520,000 sits 52.3% above the 2009 sale of £341,500. On a £-per-square-foot basis, the last sale (£599/sq ft) was about 69.4% above the typical sold price in the postcode. At 53 m² it sits well below the postcode median (81 m² across 25 EPCs), making it one of the more compact homes locally.
