Get started10a is a detached house in Great Amwell, Ware, Ware (SG12 9RN). It has a recorded floor area of 220 m² (around 2368 sq ft). The latest certificate (July 2020) returns a high B (score 86), putting the home a stone's throw from an A rating.
Held since December 1998 — that's 27 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 £1,145,000 sits 236.8% above the 1998 sale of £340,000. On a £-per-square-foot basis, the last sale (£144/sq ft) was about 53.9% below the postcode norm. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension, a conservatory and a porch, meaningful when judging how the property has evolved. Its energy rating outperforms most of the postcode (better than 86% of similar EPCs).
Achieving this rating across a home of this size is uncommon — larger homes typically score lower.
10a has been extended on multiple sides of the property across separate planning applications.
10a's estimated value is more than triple its earliest registered sale price (1998).
