Aveno permanent dossier · published 15 Aug 2026
Shards
Staplefield Road, Cuckfield, West Sussex
Independent reading
A 5,080 sq ft award-winning modernist house carved into a former quarry, with a private pool terrace, gym, sauna, four-car garaging and two landscaped acres.
Shards exceeds the Pavello benchmark. Its architecture is independently awarded, unmistakably contemporary and supported by a fresh £5m instruction, May 2026 real-property photography and a working exact-property publisher film. The decisive buyer issue is whether the £4.28m uplift from the 2019 site transaction is fully explained by the completed 2022 house, measured components, access rights and documented build quality.

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.
