About Top Flat
Top Flat is a semi-detached house in Worthing (BN11 1DL). It has a recorded floor area of 49 m² (around 527 sq ft) and construction records dating it to before 1900. The latest certificate (May 2012) shows a D (score 55), a step below the typical UK home. The recommended improvements would push it to C (score 75). The latest certificate is from May 2012, so improvements made since then won't be reflected.
Held since December 1999 — that's 26 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £182,000 sits 287.2% above the 1999 sale of £47,000. On a £-per-square-foot basis, the last sale (£89/sq ft) was about 57.7% below the postcode norm. At 49 m² it sits well below the postcode median (82 m² across 28 EPCs), making it one of the more compact homes locally.
