Langley Farm
Wigginton, Tring, Hertfordshire
Independent reading
A newly completed 5,090 sq ft cedar-and-dark-brick smart house across five levels, with full-height glazing, cinema, gym, wine room and an all-electric heat-pump specification.
Langley Farm clears Aveno's gate because its form, five-level section and technical programme make it an exceptional contemporary house rather than a conventional premium new build. The reduced £4.315m guide is about £848/sq ft on the agent's area, but that density is not decision-grade until the 5,090 sq ft marketing figure is reconciled with the 528 m² public record and the completed construction, title, landscape and building-systems pack is verified.

£848/sq ft from current guide and the current agent's approximately 5,090 sq ft / 472.9 m² marketing figure; a separate public-data distributor reports 528 m², so a signed RICS measurement must resolve the 55.1 m² difference.

Langley Farm, Cholesbury Road, Wigginton, Tring, Hertfordshire
The live Hopcroft instruction names Langley Farm on Cholesbury Road, Wigginton and supplies the exact-property film; current Rightmove distribution aligns on the £4.315m detached/freehold offer, accommodation and specification. Dacorum material and the EPC-derived record independently join Langley Farm to HP23 6JH and the replacement dwelling. The official title number and UPRN remain to be joined buyer-side.

Aveno uses only YouTube's privacy-enhanced publisher-controlled player and copies, downloads, screenshots, rehosts and hotlinks none of the film or estate-agent photography.
