Casa Tregua · Clorindo Testa, 1977
Las Mandarinas
An author’s house in the Argentine Pampa
In 1977, Clorindo Testa — one of the great masters of Argentine architecture — designed a country house on the Pampa together with Héctor Lacarra, who was both its co-author and its first owner. Every detail was studied. Almost fifty years later, Las Mandarinas is offered for sale for the first time to the international market.

The Architect
The Pampa, according to Clorindo Testa
The 1960s were a challenge for a generation of Argentine architects. Clorindo Testa became a reference on the international scene — not least for revealing, in his experimental single-family houses, the genius loci of a very particular part of Argentina: the Pampa.
The infinite space, the vastness, the forms of agricultural production and the rural buildings that already stood on the land became the material of an architecture in dialogue with its context. For Testa, the result is a spatial continuum between nature and the built.
«An architecture impregnated with the spirit of truth.»
Le Corbusier, on the rural buildings of the Pampa
The interweaving of volumes recalls one of his masters, Le Corbusier — the convent of La Tourette above all — in the play of light and the majestic roof. Sunlight enters every room through openings that are at times strictly rectilinear, at times arched.

The House
Two volumes, one landscape
Greenery surrounds a house divided into two bodies: the main one, crowned by a majestic gabled roof, and a long, low building that Raffaele Tregua transformed into the guest wing and the quincho — the “sacred” space of Argentine culture — with a typically Italian touch inside: a great Sicilian wood-fired oven.

Interiors
Light, until evening, in every season
At the heart of the house, a 70 m² living room rises 5.5 metres under an irregular pagoda-shaped ceiling of timber and steel, warmed by a great fireplace. From the studio overlooking the salon, natural light lasts until evening in every season.
Testa’s greatness lies in having ennobled an apparently “rural” type of dwelling. The children’s beds are built in wood, as if in a barn or a stable — yet within the whole design they acquire great formal value, as do the bespoke bathroom cabinets. A saloon door separates the day and night areas.

The Ceramics
The hand of Teresa Bortagaray de Testa
From the kitchen to the bathrooms, wall ceramics painted one by one by Teresa Bortagaray de Testa — ceramist, and the architect’s wife — lead guests through “fantastic” worlds: now into a jungle, now among the waves of the sea.
Working with Teresa allowed Clorindo to declare openly, in the 1970s, his support for craft over industrial production. Las Mandarinas is one of the very few Testa houses where this testimony still exists — and is beautifully preserved.



Time here is set by the apple and mandarin trees, by the roosters calling across the fields, and by the trot of horses.

The Estate
Eleven hectares of Pampa
For those who live in the great metropolis of Buenos Aires, this infinite landscape is a pause from the labyrinthine whirl of the city. A tree-lined entrance, then an estate that gives back as much as it offers: a place to rest the mind, and to make the rich land of the Pampa bear fruit.

The Plan
Drawn along the path of the sun
The original plan sets the two volumes on the diagonal between north and south, tracing the sun’s arc from east to west across the day — so that every room receives its share of light.
Three en-suite rooms for guests
The long wing, extended in 2006, hosts three independent en-suite guest rooms opening onto a shaded gallery — and the quincho, with its Sicilian wood-fired oven.

Location
Capitán Sarmiento, Buenos Aires
In the heart of the province of Buenos Aires, the estate lies just 1.5 km from the town of Capitán Sarmiento and 140 km from the capital along the Panamericana and Ruta Nacional 8 — close enough for a weekend, far enough for silence.
