Prefabricated Modern House Design: House Ibiúna by Rodrigo Ohtake
A vibrant, sustainable prefabricated modern house in Ibiúna, Brazil, designed by Rodrigo Ohtake, blending modular efficiency with bold curves.
A New Vision for Prefabricated Architecture
House Ibiúna, designed by Rodrigo Ohtake Arquitetura e Design, redefines the concept of prefabricated modern house design in Brazil. Located in Ibiúna, just 90 km from São Paulo, this 180 m² residence stands as an innovative response to modular construction, merging cutting-edge technology with architectural creativity. Designed as a weekend retreat for Ohtake and his family, the home exemplifies sustainable building strategies while embracing organic forms and vibrant colors.



The Concept: Prefabrication Meets Creativity
The project originated from an invitation by Syshaus, a pioneer in prefabricated homes, to create a design that broke away from conventional modular aesthetics. Inspired by the teachings of his father, architect Ruy Ohtake, Rodrigo aimed to create housing that was not only cost-effective and sustainable but also expressive and unique. The challenge was to introduce curves and bold forms into a system traditionally associated with rigidity and standardization.


Construction Approach: Modular Precision with Artistic Freedom
House Ibiúna was manufactured at the Syshaus factory in just 90 days and installed on-site in 30 days, demonstrating the efficiency of prefabricated systems. Built with metallic components, glass, and thermally insulated industrial panels clad in aluminum, the structure ensures durability and energy efficiency. The house rests on a plateau, fully integrated into its natural setting, and features a roof garden, further enhancing its ecological footprint.



Architectural Features: Curves, Colors, and Transparency
Rodrigo Ohtake’s architectural language—defined by dynamic curves and vibrant colors—is evident throughout the residence. Self-supporting roof tiles were customized to achieve sweeping curved forms, while curved walls and eaves soften the rigid modular geometry. A striking feature of the exterior is the blue perforated steel brise-soleil, adding privacy to the bedrooms while enhancing visual dynamism.



Inside, the orange-toned interiors create a vivid contrast with the lush green landscape outside. Expansive glass panels blur the boundaries between interior and exterior, immersing inhabitants in nature and eliminating the need for curtains in bedrooms. The social areas—living, dining, and kitchen—are positioned between the modular bedroom volumes, creating an open, fluid space for family gatherings.


Interior Design: A Dialogue of Art and Architecture
The interior reflects Rodrigo’s design ethos, with custom-designed furniture and art pieces curated by his wife, Ana Carolina. This synergy between architecture and art transforms the home into a vibrant cultural experience, embodying modern Brazilian design sensibilities.


Sustainability and Efficiency: A Smarter Way to Build
Prefabrication significantly reduced construction waste, transportation costs, and environmental impact. The integration of thermal insulation panels, efficient brise-soleils, and natural ventilation ensures a comfortable, energy-conscious living environment. House Ibiúna is not only a family retreat but also a prototype for future sustainable modular homes in Brazil.
Redefining the Future of Prefabricated Modern Homes
House Ibiúna challenges preconceived notions of prefabricated architecture by proving that modularity and artistic freedom can coexist. Rodrigo Ohtake’s design sets a benchmark for prefabricated modern house design, combining sustainability, functionality, and aesthetic innovation. This residence demonstrates how industrialized construction can deliver bespoke architecture without compromising creativity or quality.
