Architecture20/20
John Pardey with Magnus Ström, 2012
Aveno permanent dossier · published 19 Aug 2026
Vitro House
Marlow Road, Bourne End, Buckinghamshire
Independent reading
A 3,314 sq ft John Pardey and Magnus Ström house with a timber-cantilevered upper storey, Bulthaup kitchen, MVHR, solar panels, EPC A and secluded National Landscape views.
Authorship, formal clarity, environmental performance and a publisher-controlled architectural film make this a pure Pavello-level admission despite its lower £2.95m price; the principal value question is the premium over larger but architecturally weaker local houses.

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.

All property film and photography remain publisher-controlled. Only the live film player and original Aveno evidence graphics are permitted; social stills require separate written permission. The exact-property film remains inside the publisher-controlled Dacast player exposed by the live listing. Aveno copies, downloads, screenshots, rehosts and hotlinks none of the agent media. The dossier retains an Aveno evidence panel and direct publisher/source links if the remote player is unavailable; no broken-image panel is rendered. Third-party material remains the property of its publisher. The publisher does not endorse Aveno’s independent assessment.

From the Aveno Journal
An EPC A is not a running-cost guarantee
Vitro House shows that serious architecture and excellent energy performance can coexist. A buyer still needs measured bills, maintenance records and a systems map before treating an A rating as a cost forecast.
