The House

We sell very fewhouses, very well.

Eleanor Vane opened the Hay Hill office in 1987 with a single conviction: that a house of real quality is not a listing to be distributed, but a position to be represented. Nearly four decades on, that is still the whole of the method.

We take on fewer than forty instructions a year. Each is surveyed before it is offered, photographed by our own team, and carried by a named principal from the first viewing to the day the keys change hands. We turn away more than we accept, and we say so plainly when a house is not ready to be sold.

The register that results is small, slow to change, and known to perhaps three hundred people worldwide. That is the point of it.

Four things wewill not trade.

These are not services. They are the conditions under which we agree to act, and they have not changed since 1987.

Representation

Fewer than forty a year

We decline more instructions than we accept. A residence we represent has our full attention, our own photography, and a named principal on the file from first viewing to completion.

Discretion

Off the open market

Two thirds of what we sell is never advertised. Private releases go to a register of qualified buyers we have known, in many cases, for a decade or more.

Provenance

The whole history, in writing

Title, architect, restoration record, servitudes, planning consents. We commission independent survey before a residence is listed, not after an offer is made.

Stewardship

The relationship outlasts the sale

Staffing, insurance, seasonal opening, restoration oversight. Most of our clients retain us long after completion, and many return to us to sell.

What the houses hold

Not amenities.Simply what is there.

A private mooring is not a selling point. It is a reason the house was built where it was.

InvestmentFive markets

Where scarcityis structural.

In four of the five markets we work in, planning constraint — not demand — sets the ceiling on supply. That is the whole thesis.

We advise on acquisition, holding structure and eventual exit. Where we do not have a view, we say so and introduce someone who does.

Figures are illustrative, drawn from our own transactions to March 2026, and are not a forecast. The hairline beneath each market shows how constrained supply is relative to the others.

They talked us out of the first two houses we wanted. The third we have now owned for eleven years, and not a season has passed where we questioned it.

Four people. Everyfile has a name.

You will meet the principal at the first viewing and deal with the same person at completion. We do not pass files between desks.
