About Barn Cottage
Barn Cottage is a four-bedroom detached house in Clayton, Hassocks, Hassocks (BN6 9PL). It has a recorded floor area of 168 m² (around 1808 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (February 2012) shows an F (score 38), near the bottom of the EPC scale. The recommended improvements would push it to E (score 44). Main heating runs on oil. The latest certificate is from February 2012, so improvements made since then won't be reflected.
Today's modelled estimate of £1,365,000 sits 51.7% above the 2012 sale of £900,000. On a £-per-square-foot basis, the last sale (£498/sq ft) was about 100.2% above the typical sold price in the postcode. 8 planning records sit against the property, 5 approved, 2 refused. Past consents include an extension, a garage conversion and a porch, meaningful when judging how the property has evolved. At 168 m² it's 21.5% smaller than the typical home in the postcode (214 m² median across 7 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). Last sold in October 2012, so it's been off the market for around 14 years.
