COLLECTIVE HOUSING

We specialize in designing forward-thinking multifamily residences. We create efficient, welcoming spaces where shared living connects with architectural innovation. With over a decade of experience in BIM implementation, we ensure seamless integration from concept to completion—optimizing every stage of design, construction, and coordination.

TAILORED ARCHITECTURE

We design signature homes—bespoke residences that combine architectural excellence with exceptional attention to detail. Each single-family home is a personal statement, tailored to reflect the lifestyle and identity of its owners, blending elegance and innovation in every line.

SUSTAINABLE HOMES

We create sustainable homes that combine energy efficiency, comfort, and design. With low-impact architecture and smart technology, our houses promote a healthy lifestyle in harmony with nature. One example is our Green Nest House, a Passivhaus concept that integrates design and technology to provide a comfortable, eco-friendly home—ideal for eco-resorts.

20 years,

A journey of innovation, design, and transformation. To celebrate two decades of experience, we have selected 20 projects that define our legacy. ON-A has crafted unique spaces where technology, sustainability, and creativity converge. For 20 years, we’ve been transforming ideas into architecture—connecting people, enhancing cities, and shaping the future. With the same passion, we continue to explore new horizons and build a more inspiring world.
