The Spinney
Sandpit Lane, St Albans, Hertfordshire
Independent reading
A £3.975m, 4,896 sq ft St Albans house transformed in 2018 around double-height glazing, a split-level Miele kitchen and six suites, held within 0.70 private acres.
The Spinney clears Aveno's gate through a coherent 2018 transformation, detached form, private landscaped setting and unusually strong connection between the dramatic double-height entrance and split-level family plan. The £812/sq ft asking density is transparent, but it is not yet supported by an exact prior sale or a like-for-like modernised transaction. Price only after the legal identity, 2018 planning-and-completion archive, signed measurement, works ledger and operating evidence agree.

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.

- The split-level kitchen and family room was redone in 2018 and is attributed with Miele appliances, a water softener, island seating and direct garden connection.

Primary publisher · visual-rights recordFine & Country St AlbansOpen original source ↗Open rights-basis evidence ↗
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. Fine & Country publishes the exact-property tour for The Spinney through its public YouTube channel. The film title repeats the current £3.975m price, 0.70-acre setting and St Albans location, while the description names The Spinney and its six bedrooms. 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. 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.
