The Experimental House by OHMA Design: A Harmonious Blend of Nature and Innovation

The Experimental House by OHMA Design is a stunning exploration of rural living, born from the unique life story of its resident. A curious and adventurous individual with a background in biochemistry and pharmacy, she envisioned a home that could serve as her personal laboratory—a space to experiment with living harmoniously in the countryside. Construction began in 2016, with the first phase allowing her to inhabit the house while planning the second phase, which was completed in 2023.

Architecture That Celebrates Nature

Strategically positioned in a valley, the Experimental House is designed to integrate seamlessly with its surroundings. The architects placed windows to capture the best views, including the living room’s stunning perspective of a preserved native forest abundant with Araucaria trees. The house emphasizes visual and physical contact with nature, encouraging residents to engage with the landscape both inside and outside the home.

The structure employs natural regional materials, promoting sustainability and harmony with the environment. Sandstone and white sandstone sourced from Serra Gaúcha quarries, along with locally collected wood crafted by skilled artisans, form the core of the house’s material palette. These materials are used for doors, pergolas, ceiling linings, decking, and even custom furniture, creating a warm and organic aesthetic. Exposed concrete pillars and ceiling details add subtle modernity, balancing the rustic charm.

Sustainable and Thoughtful Interior Design

The interior of the Experimental House embodies the same philosophy of reuse and sustainability. Doors reclaimed from demolition sites, a 1940s vintage bathtub, and a repurposed spiral staircase highlight the home’s narrative of historical continuity and self-connection. The spiral staircase, painted in a striking blue, serves as a visual centerpiece, bridging the home’s first and second phases while connecting lower and upper levels.

A natural pool crafted from sandstone and fed by a nearby spring reinforces the home’s integration with the natural surroundings. The living spaces feature a cozy fireplace, blending comfort with the rustic elegance of the house. Every element, from artisan-crafted wood to recycled architectural details, reflects a story of kindness, respect for craftsmanship, and environmental mindfulness.

Landscape and Exterior Design

The landscaping complements the architecture, featuring hydrangeas native to the region, while the home’s positioning in the valley allows for constant interaction with wind, rain, and seasonal changes. This exposure contributes to a natural aging process, giving the home a poetic character that evolves over time. The blue-painted back entrance acts as a symbolic portal, marking a transition from the external landscape to the interior sanctum.

A Poetic Experiment in Rural Living

The Experimental House is more than a residence—it is a personal exploration of rural life, sustainability, and architectural storytelling. From reclaimed materials to regionally sourced stone and artisan-crafted wood, the house harmoniously combines eco-friendly design, modern comfort, and a deep connection to nature. Each architectural decision reflects the resident’s curiosity and desire to create a home that evolves gracefully with time.
