About Hanga House

A marketplace built
for serious collectors
of contemporary editions.

Hanga House began in 2024 with one question: why is buying a £30,000 Hockney print online still less considered than buying a £30 book? We rebuilt the process — verification first, listing second, sale only when everyone is confident.

01 ——— Our Standard

We catalogue the way a serious gallery would.

Specialist-first review

Every submission is read by a print-market specialist before it becomes a listing candidate. We start with authorship, edition logic, physical cues, and whether the work belongs on the marketplace.

Independent second opinion

Works above material thresholds, or by artists with known authentication complexity, are escalated for external consultation before publication.

Provenance documented forward

We look for the chain of ownership from publisher, gallery, auction house, or prior collector forward — and note what is missing rather than hiding it.

Condition without euphemism

Raking-light notes, paper handling, margins, colour, framing history, and conservation flags are treated as buying information, not sales friction.

Pricing without theatre

Seller-first pricing means clear fee economics: 0% seller fees, a 12% buyer premium, and no invented urgency.

02 ——— People

A small team of specialists.
