Celebrated on the first Monday of October, World Architecture Day honors the art and science of designing human spaces. Established in 1949 and aligned with the UN World Habitat Day in 1996 by the International Union of Architects (UIA), it recognizes not only the discipline itself but also the vital role architects play in building a more harmonious, sustainable, and inclusive world.
In 2025, the theme “Design for Strength” highlights architecture’s ability to foster resilience: buildings that withstand the test of time, cities that adapt, and communities that find refuge and connection in the built environment. The strength referred to goes beyond structures—it is also human, creative, and symbolic, reflecting architects’ commitment to a balanced and inspiring future.
Architects act as mediators between people and their environment, interpreting collective needs and shaping urban life. Every project carries the responsibility to promote well-being, beauty, and sustainability—principles that define today’s cities and envision tomorrow’s.

OTIIMA shares this vision, reaffirming its commitment to natural light. Our solutions, which blur the boundaries between interior and exterior, make light the centerpiece of every space. Minimalist framing systems represent innovation, transparency, and the intimate connection between people and their surroundings.
In this way, OTIIMA translates architectural philosophy into designs that honor light, materials, and simplicity, fostering human-centered and authentic architecture, where each project is a dialogue between technology, nature, and sensitivity.
