HALDEN

(01) — The Studio

Fig. 1 — Hallway, Kessel House
Engadin, 07:40

We represent fewer than forty homes a year. Each is chosen the way one might choose a place to grow old — for its light, its silence, and the view it keeps to itself.

HALDEN is a private brokerage for architecturally significant residences. We work quietly — often before a house is ever listed — for owners who would rather not be found, and buyers who already know what they are looking for.

HALDEN is a private brokerage for architecturally significant residences. We work quietly — often before a house is ever listed — for owners who would rather not be found, and buyers who already know what they are looking for.

From the Engadin to the Atlantic coast, every residence we offer has been walked, photographed and lived in by a partner of the firm. If we would not stay the winter, we do not take the listing.

(02) — Selected Residences

Houses that keep
their silence.

A rotating collection of eight residences, each offered privately. Particulars, floor plans and viewings are shared on request, under agreement.

(04) — The Partners

The people who answer the phone.

Each territory is held by a single partner who lives there — someone who knows the roads, the architects and the neighbours, and who will still be there after the keys change hands.

Portrait of Henrik Solberg, Founding Partner, Lofoten

Henrik Solberg

Founding Partner, Lofoten

A former fisherman turned conservationist, Henrik represents a very small number of cabins and farmhouses above the fjords. He will tell you honestly what a Lofoten winter asks of a house, and of its owners.

Andri Brenner

Partner, Engadin

Born in Samedan and trained as an architect in Zürich, Andri has spent two decades placing families in the high valleys. He knows which roads stay open in February and which chalets hold their warmth.

Portrait of Tomás Vidal, Partner, Mallorca

Tomás Vidal

Partner, Mallorca

Tomás restored his first finca on the Tramuntana coast at twenty-six. Today he represents a handful of houses each year, most of which change hands without ever being photographed.

Portrait of Duarte Marques, Partner, Comporta

Duarte Marques

Partner, Comporta

A Lisboeta who moved south for the light, Duarte has watched Comporta change from rice fields to a quiet refuge. He is careful about the houses he represents, and more careful still about their buyers.

Portrait of Luca Ronchi, Partner, Lake Como

Luca Ronchi

Partner, Lake Como

Luca grew up in a boathouse on the western shore. He advises on historic villas and their gardens, and can tell you which terraces keep the evening sun long after the ferries have stopped.

Nikos Kallas

Partner, The Cyclades

Nikos divides his year between Athens and Paros. He works with a small circle of island architects and specialises in homes that are built, as he puts it, to disappear into the hillside.

Discretion is the service.

Off-market acquisition

Most of the houses we sell never appear online. We introduce buyers to homes privately, under agreement, before anyone else knows they exist.

Considered sale

For owners, a quiet campaign: architectural photography, a written portrait of the house, and a shortlist of qualified buyers rather than an audience.

Architectural counsel

Surveys, restoration studies and planning opinions before an offer is made — so you understand the building as well as its architect did.

Long stewardship

After the keys, we stay. Caretaking, staffing, seasonal opening and closing — handled by the same partner who found you the house.

(06) — In confidence

“They found us a house that was never for sale, and made its owner glad to part with it. Two winters on, it still feels like a secret.”
