Independent recognition, authorship, integrity, rarity and the relationship between house, setting and story.
The Aveno method
Independent.
Not antagonistic.
Aveno separates what a publisher says, what an official source supports, what the model estimates, and what remains unknown. Better evidence can change the conclusion.
The Aveno admission gate
Beautiful is common.
Remarkable is earned.
A home enters the main Aveno collection only when it clears both gates. Older records that have not yet passed this audit remain visibly labelled as provisional or legacy studies.
Identity, current market facts, transaction memory, energy, planning/heritage, environment, comparables and ownership costs.
Exact address, UPRN or a defensible reconciliation before property-level official records are joined.
Statutory listing, respected awards, published architectural record or equivalent third-party authority.
A legible architectural idea, known designer or exceptional vernacular intelligence—not decorative luxury.
Original spatial logic, fabric and important details survive, or restoration is unusually disciplined.
A scarce typology, material system, social history, adaptive reuse or technical idea worth understanding.
Landscape, topography, place and human story materially shape the house rather than merely surround it.
Identity before inference
No official-data match is attached until the address, coordinate or UPRN is sufficiently resolved.
Dimensions, not a brutal total
Architecture, market position, ownership intensity, constraints and evidence coverage remain visible separately.
Constructive language
We explain the premium, question or missing evidence. We do not score an agent’s competence or manufacture controversy.
No paid score
Agents can correct facts and provide evidence. Commercial relationships can never purchase a higher assessment.
How judgment is expressed
Honest enough to matter.
Calm enough to use.
“The asking price carries a material premium over the available evidence. Architectural significance may justify part of it; stronger matched sales would be needed to support it fully.”
Public language evaluates the evidence and the buyer decision—not the dignity or professionalism of the selling agency.
Source architecture
Official where possible.
Explicit where not.
Every connection has a date, source and evidence state. A blank is not silently converted into a zero.
Transactions
HM Land Registry Price Paid Data
Monthly sales evidence; exact matching and design relevance still matter.
Official source ↗EnergyEPC data service
Bulk data and developer API; certificate matching needs an address or UPRN.
Official source ↗PlanningPlanning Data API
More than 100 datasets, queryable by coordinate or UPRN; coverage can be incomplete.
Official source ↗HeritageHistoric England Open Data
The official National Heritage List and spatial downloads/APIs.
Official source ↗EnvironmentEnvironment Agency data
Flood layers describe areas and scenarios; they are not a property survey or insurance quote.
Official source ↗ConnectivityOfcom Connected Nations
Address-level APIs are available subject to registration and terms.
Official source ↗A daily run may publish only when remarkability is at least 80, data readiness at least 70, identity confidence at least 80, the current source is verified, the writing is independent, media use is lawful and uncertainty is visible. If any hard gate fails, the candidate is held in research rather than added to the public collection.
