About Baymill
Baymill is a three-bedroom detached house in Copsale, Horsham, Horsham (RH13 6QU). It has a recorded floor area of 123 m² (around 1324 sq ft), construction records dating it to 1991-1995 and council tax band F. The latest certificate (December 2012) shows an E (score 50), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since July 2009. Between certificates, roof efficiency went from Average to Good. The recommended improvements would lift it to B (score 81), a 3-band jump. Main heating runs on oil. The latest certificate is from December 2012, so improvements made since then won't be reflected. Other recorded features include notable views. Our model identifies extension potential, subject to local planning policy.
Held since August 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. Today's modelled estimate of £722,000 sits 50.4% above the 2009 sale of £480,000. 3 planning records sit against the property, 2 approved, 1 refused. Past consents include a loft conversion and an extension, meaningful when judging how the property has evolved.
