Contemporary private commission; named architect to verify
Aveno permanent dossier · published 21 Aug 2026
Bois Lane Residence
Chesham Bois, Amersham, Buckinghamshire
Film by Vale and Chilterns
Independent reading
A secluded 5,782 sq ft contemporary house with double-height hall, 36-foot split-level living room, cinema, 50-foot terrace, roof terrace, studios and landscaped 0.72-acre gardens.
The architecture, indoor-outdoor sequence, privacy, finish and exact live film clear the Pavello visual standard; publication readiness is deliberately capped until the legal number/name is disclosed and joined to title and planning records.

Property memory
The home’s price story.
Direct transaction memory is not yet matched.
This history does not prove fair value. It tells the buyer exactly how much of the current price must be explained by market growth, improvements, specification and scarcity.
Official evidence map
What is matched.
What is withheld.
Land Registry can establish sale history; EPC can reveal rated floor area and energy assumptions; Planning Data can surface constraints by UPRN or coordinate. A link alone is never counted as intelligence.
