Keshaw McArthur: Openfield House

Keshaw McArthur: Openfield House

At its core, Openfield House is defined by a simple proposition: what remains when architecture is reduced to its most permanent elements. The project distinguishes between what is fixed and what is temporary, imagining a future in which the lightweight components fall away, leaving behind a composition of stone objects embedded in the ground. This conceptual clarity is expressed through a series of heavy concrete volumes that rise directly from the terrain. These elements anchor the house, forming its centre and giving weight to the otherwise open field of occupation. Around them, lighter cedar-clad volumes gather beneath a corrugated metal...
Arquitectura G: Patio House

Arquitectura G: Patio House

Patio House by Arquitectura-G, located in Costa Brava, is conceived as a calm architectural response to a sloping landscape, where built form and terrain are carefully interwoven. Rather than asserting a dominant gesture, the project follows the existing contours, organizing the house as a sequence of spaces structured around a central open void. At the heart of the design lies a square courtyard measuring 15 by 15 meters. This open space, defined by a grid of slender columns, contains a reflecting pool and three trees, establishing a quiet focal point for the dwelling. The surrounding colonnade operates as a transitional...
BARD YERSIN: The Inverted Farm

BARD YERSIN: The Inverted Farm

The Inverted Farm by BARD YERSIN architectes is a conversion project in La Bruyère, Vuisternens-devant-Romont, that transforms a typical 19th-century regional farmhouse. Originally designed to bring dwelling and agricultural functions together under a single roof, the building faced modern challenges. It was deprived of its farming use, located outside the building zone, and featured an exceptionally large volume that was difficult to maintain given the limited habitable floor area permitted. In this context, the client’s mixed housing and permaculture program represents a rare opportunity for a coherent requalification of the whole. Because the single-storey surface of the existing dwelling is...
Enzo Valerio: Pinetum

Enzo Valerio: Pinetum

In 2018, a competition was held for a new pavilion in the Pinetum Blijdenstein botanical garden in Hilversum, attracting 135 architectural firms, including several prominent international names. Following a rigorous selection process, which narrowed the field to eight, then four, proposals, Enzo Valerio's design was selected as the winning entry. Over the next few years, the design evolved through close collaboration with Pinetum Blijdenstein, alongside efforts to secure funding for construction. After obtaining a building permit in 2022, numerous tests, material samples, and design iterations were conducted, culminating in the pavilion’s initial staking out in March 2023. Enzo Valerio’s studio...
