About 9 High Street
9 High Street is a mid-terrace house in Marlow (SL7 1AU). It has a recorded floor area of 87 m² (around 936 sq ft), construction records dating it to before 1900 and council tax band E. At 87 m² this is the largest unit on EPC record across the building (48–87 m²). The building's EPC ratings span F to C across 7 units on file. The latest certificate (August 2020) shows a D (score 55), a step below the typical UK home. When first surveyed in July 2009 the rating was F, the property has climbed 2 bands since. Between certificates, hot-water efficiency went from Average to Good, lighting went from Average to Very Good and main heating went from Average to Good.

Today's modelled estimate of £475,000 is 58.7% below the 2017 sale of £1,150,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. At 87 m² the property is well over the postcode median (60 m² across 6 EPCs), placing it in the larger end of the local stock. 14 planning records sit against the property, 7 approved, 6 refused, 1 pending. Past consents include partial demolition, meaningful when judging how the property has evolved. An application is currently awaiting a decision. The record references listed-building consent, which constrain future alterations. Last sold in January 2017, so it's been off the market for around 9 years.
