Luna House by Pezo von Ellrichshausen – Monumental Architecture at the Foot of the Andes

Nestled in the landscapes of Yungay, Chile, the Luna House by Pezo von Ellrichshausen is a striking architectural landmark completed in 2022. Spanning 2,400 m², the project transcends the conventional definition of a house, blending qualities of a residence, museum, and cloister into one monumental spatial experience.

Positioned at the foot of the Andes mountain range, Luna House is conceived as a collection of twelve interconnected buildings, separated by visible seismic joints. This unique structural composition transforms the project into a series of massive concrete blocks, creating both unity and fragmentation. The architects deliberately blur the line between domesticity and monumentality, suggesting that to call it simply a “house” is too limiting, while calling it a “museum” would be too modest.

The building’s plan follows a square footprint divided by an asymmetrical cross, organizing a sequence of rooms arranged around four distinct courtyards. Each courtyard presents a unique spatial and natural relationship:

• A long courtyard aligned with the rising and setting sun, following the natural slope of the land.
• A flat northern courtyard marked by a water stream, connecting a solitary hazelnut tree with two triangular edges.
• A circular courtyard featuring a vibrant flower garden, emphasizing directionless serenity.
• A vast courtyard, nearly the size of a traditional Chilean medialuna bullring, with a pond and mature trees, from which the house derives its name.

This careful choreography of interior and exterior spaces blurs distinctions between living, working, and contemplation, allowing areas for painting, writing, or gardening to coexist seamlessly with residential functions. Openings in multiple directions provide shifting atmospheres of intimacy, weight, emptiness, and monumental presence.

The architecture emphasizes horizontality through its extended rooflines and subtle transitions from one to two levels. Despite its handcrafted concrete walls being relatively thin, the structure conveys a fortified and monumental character, softened by details such as cornices, eaves, and rounded courtyard edges. The resulting design balances brutal materiality with poetic spatial sequences, offering a powerful meditation on architecture, landscape, and human experience.
