10b, Arundel Street, Brighton, BN2 5TG

10b is a two-bedroom detached house in Brighton (BN2 5TG). It has a recorded floor area of 97 m² (around 1039 sq ft), construction records dating it to 1900-1929 and council tax band B. At 97 m² this is the 27th smallest of 37 units on EPC record in the building, where floor areas span 33–175 m². The building's EPC ratings span E to C, with this unit at the top. The latest certificate (November 2008) shows a C (score 69), just inside the C band. The latest certificate is from November 2008, so improvements made since then won't be reflected.

It hasn't traded since October 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 97 m² the property is well over the postcode median (72 m² across 36 EPCs), placing it in the larger end of the local stock. Across 2006–2009, sale prices on this property compounded at 2.2% per year. Today's modelled estimate of £317,000 sits 66.9% above the 2009 sale of £189,950. On a £-per-square-foot basis, the last sale (£183/sq ft) was about 25.9% below the postcode norm. One planning record on file: an extension approved in 2001. Past consents include an extension, meaningful when judging how the property has evolved.
