Cashew Garden House Vietnam – A Sustainable Retreat by G+ Architects

Introduction to Cashew Garden House

The Cashew Garden House, designed by G+ Architects, is a serene retreat and small-scale homestay on the edge of Nam Cát Tiên National Park, Vietnam. Built in 2024, the project embraces a sensitive architectural approach to preserve 26 mature cashew trees that originally occupied the 1000 m² site. The design showcases how architecture can harmonize with its natural environment, prioritizing minimal impact and sustainable material use while creating a warm, livable home.

Site Context and Design Approach

Located in southern Vietnam, the Cashew Garden House integrates seamlessly with the lush tropical landscape of Nam Cát Tiên. The design process began with the primary requirement to protect every existing tree. On-site surveys and a 1:1 scale mock-up were used to refine the layout, ensuring that the construction did not disturb root systems while allowing for functional circulation.

The resulting architectural form consists of sloped roofs, staggered wall heights, and open verandas oriented to the microclimate. Eastern verandas are elevated to welcome the soft morning light, while western facades are shaded by the dense tree canopy to reduce solar heat gain.

Sustainable Features and Climate Response

A central pond functions as a natural cooling system, regulating indoor temperatures, enhancing biodiversity, and visually connecting different building volumes. This water element, combined with strategic openings and shaded verandas, creates a naturally ventilated environment that reduces reliance on mechanical cooling systems.

Materiality and Construction Techniques

The Cashew Garden House Vietnam highlights the reuse of local materials, including reclaimed wood, clay tiles, unfinished plaster, and natural stone. These choices not only minimize environmental impact but also blend seamlessly with the surrounding landscape. Construction was carried out by local laborers, with physical models replacing conventional drawings to ensure precision and cultural alignment. A master carpenter from Binh Thuan province skillfully crafted the wooden elements, maintaining the authenticity and tactile quality of each reused component.

Interior Spaces and Adaptive Design

The interiors of the Cashew Garden House are designed for comfort and connection to nature. An existing structural frame was repurposed to create the kitchen and dining area, reducing the need for new materials. Warm wood finishes, exposed beams, and minimalistic detailing emphasize the rustic charm and allow natural light to fill the spaces.

Bedrooms are oriented towards garden views, while open dining and communal areas extend into the verandas, blurring the boundary between indoor and outdoor living.

Post-Occupancy and Living Experience

Six months after completion, the Cashew Garden House Vietnam demonstrates excellent performance. The owner reports a stable indoor climate, minimal insect intrusion, and a heightened sense of connection to the natural surroundings. The garden has flourished, creating a self-sustaining micro-ecosystem that complements the home’s quiet and contemplative lifestyle.
