Vegetable House by Facundo S. López: A Sustainable Architectural Experiment

Introduction to the Vegetable House

Located in Arana, Argentina, the Vegetable House by Facundo S. López is a pioneering residential project that explores sustainable construction using wood and thatch materials. Designed in 2022, the 62 m² structure embodies an architectural philosophy that merges vernacular traditions with contemporary techniques to create an eco-friendly, cost-effective home.

The Vision: Designing a Personal Sanctuary

Unlike his previous projects, this house posed a unique challenge for the architect—it was his own home. The design process was an introspective journey, incorporating 20 years of experience into a compact, sustainable dwelling. Situated in a semi-rural area near La Plata, the site was chosen serendipitously, surrounded by vegetation, railway tracks, and open fields. Before urban development reached the area, the landscape was home to grazing cattle and soaring birds, providing an untouched, tranquil setting.

Architectural Concept: A Blend of Past and Present

The project initially explored various design inspirations, from Latin American megarons to elevated houses on pilotis similar to those in Chiloé, Chile. However, the final design was guided by practicality and a desire for impermanence. The lightweight, thatched roof became the defining feature, reflecting an emerging industry in Argentina that promotes natural, locally sourced materials. This approach emphasized a temporary yet adaptable structure, built for the present rather than eternity.

Structural Design: Merging Functionality and Aesthetics

The Vegetable House employs a double-roof system, a technique inspired by traditional homes in temperate climates. Beneath the thatched roof, a wooden box structure was meticulously designed based on material availability and economic feasibility. By offsetting the box within the thatched roof, the design introduced a shaded gallery—a reinterpretation of the ranch-style veranda, ideal for Argentina's plains.

Sustainable Construction Methods

The construction system integrates diverse architectural influences, from North American wood-frame structures to Japanese minka and Glenn Murcutt’s passive design strategies. The house prioritizes sustainability and resource efficiency, using:

• Eucalyptus and willow for the thatched roof structure, sourced from various Argentine provinces.
• Recycled hardwood sleepers from old railway tracks for the foundation.
• Implanted pine for the main structural framework.
• Plywood paneling for the building envelope.
• Eucalyptus rostrata for the flooring, offering durability and a warm aesthetic.

A New Architectural Paradigm

The Vegetable House embodies an architectural philosophy that prioritizes eco-conscious design, material efficiency, and adaptability. Rather than a conventional home, it resembles a living organism, evolving with its environment. By seamlessly integrating traditional techniques with modern sustainable practices, Facundo S. López presents a vision for the future of residential architecture—a home rooted in nature yet open to contemporary innovation.
