12a, Arundel Square, London, N7 8AT
About 12a
12a is a semi-detached house in London (N7 8AT). It has a recorded floor area of 103 m² (around 1109 sq ft) and construction records dating it to before 1900. The latest certificate (May 2022) shows a C (score 75), near the top of the C band.
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. At 103 m² the property is well over the postcode median (45 m² across 44 EPCs), placing it in the larger end of the local stock. Across 2002–2009, sale prices on this property compounded at 8.3% per year. Today's modelled estimate of £1,062,000 sits 77% above the 2009 sale of £600,000. One planning record on file: an extension approved in 2004. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
