About Dorchester House
Dorchester House is a five-bedroom detached house in Ascot (SL5 0AT). It has a recorded floor area of 206 m² (around 2216 sq ft), construction records dating it to 1996-2002 and council tax band H. The latest certificate (March 2012) shows a D (score 67), on the cusp of jumping into the C band. Earlier certificates rated it C (January 2010); the latest reading is one band lower. Between certificates, lighting went from Poor to Average. The recommended improvements would push it to C (score 72). The latest certificate is from March 2012, so improvements made since then won't be reflected. Other recorded features include a basement.
Untraded for 26 years, with the last transfer in June 2000. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time.
