Get startedAshdown House is a semi-detached house in Worthing (BN11 1DF). It has a recorded floor area of 48 m² (around 517 sq ft) and construction records dating it to 1983-1990. At 48 m² this is the 3rd smallest of 6 units on EPC record in Ashdown House, where floor areas span 45–63 m². The latest certificate (June 2023) shows a C (score 73).
Today's modelled estimate of £434,000 is 12.3% below the 2009 sale of £495,000, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£958/sq ft) was about 391.8% above the typical sold price in the postcode. Held since March 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 48 m² it's 28.9% smaller than the typical home in the postcode (68 m² median across 42 EPCs).
The latest sale fell during the post-2008 dip, often a low-water mark in price comparisons.
