Finches

Frithsden Copse, Potten End, Hertfordshire

Independent reading

A 2019 HUF HAUS of glass, Scandinavian pine and double-height space, set behind gates in an acre adjoining the National Trust's Ashridge Estate.

Finches clears the Pavello benchmark through unmistakable HUF architecture, a £3.5m guide, exceptional daylight, precise German engineering, one-acre privacy and direct access to National Trust woodland. The current £870/sq ft headline uses the 4,021 sq ft marketing figure; an older 305 m² record and the 2018 £1.4m predecessor/site transfer make the completion history and a current RICS component measurement central to value.
