In an era where urban density often distances us from the natural world, biophilic home design reconnects us to its source. It’s a philosophy, a return to the organic connection between people and place. Rooted in the belief that human well-being flourishes when surrounded by nature, biophilic design invites light, air, water, and greenery into the very structure of our daily lives. It softens boundaries, dissolves barriers, and opens interiors to the healing presence of the outdoors. At OTIIMA, we see minimal frames not just as tools of transparency, but as portals to presence. Our systems are about dissolving walls, not simply through glass, but through feeling. Biophilic design is based on the idea that humans thrive when connected to nature. In residential architecture, this translates into the thoughtful use of natural materials, ample daylight, fresh air circulation, and the integration of plants and outdoor views. When applied effectively, these elements improve comfort, boost mental clarity, and support overall well-being, turning a house into a healthier and more balanced living environment. Here are three houses where OTIIMA becomes the quiet conduit between architecture and nature: Touching Eden House | Wallflower Architecture + Design Singapore

Elevated above the urban landscape of Ghent, a private residence by Glenn Sestig Architects reinterprets the interaction between architecture and its atmospheric context. This apartment exemplifies architectural innovation and meditative design, transcending mere functionalism to emphasize the essential.  The architectural language is characterized by clarity, featuring clean lines and monolithic surfaces that establish a sophisticated aesthetic. A minimalist palette comprising travertine walls, smooth concrete ceilings, and soft beige flooring provides a cohesive backdrop for the living spaces. The interiors are fundamentally influenced by natural light rather than ornamental elements, demonstrating a meticulous approach to geometry, proportion, and detail.

The 19th Venice Architecture Biennale, curated by Italian architect and MIT professor Carlo Ratti, opened this year under the provocative theme “Intelligens. Natural. Artificial. Collective”. At the intersection of these forms of intelligence stands architecture, and, quite literally, the hands that bring it to life. Among the many national pavilions and installations taking center stage in Venice, two remarkable projects stand out for their strong conceptual vision and technical precision. Both were made possible by the expert collaboration of Portuguese-based ArtWorks.  Eco Folie: Rethinking Survival Architecture in the Atacama Desert Designed by Chilean architects Pedro Alonso and Pamela Prado, Deserta Ecofolie is a minimalist housing prototype created for one of the most extreme environments on Earth: the Atacama Desert. With a just 16 square meters footprint, this compact structure is a statement of resilience and innovation.
