1+1>2 Architects

Established in 2003 by architect Hoang Thuc Hao and colleagues from the Hanoi University of Civil Engineering, 1+1>2 Architects is a highly respected, award-winning architectural practice based in Hanoi. The firm has built a strong national and international reputation for its commitment to ecological and cultural diversity, seamlessly blending vernacular Vietnamese design with modern sustainability. While widely celebrated for its community, educational, and cultural projects, the studio also brings its high-end, reality-focused design philosophy to the residential sector.

For international buyers and expatriates looking to purchase or build a home in Hanoi, 1+1>2 Architects offers premium residential architecture and interior design services. The firm specializes in creating bespoke, environmentally conscious homes that integrate local materials, natural light, and native landscape elements. Their residential portfolio features unique, context-driven concepts—such as the acclaimed "Jackfruit Village" (Làng Mít)—which showcase how the firm harmonizes high-end living spaces with the surrounding natural topography and local heritage.

While the firm’s primary client base consists of local property owners, they are well-equipped to guide foreign non-residents through the design and construction process in Vietnam. The studio operates in both Vietnamese and English, facilitating smooth communication and collaboration for international clients. This bilingual support, combined with their deep understanding of local building regulations, material sourcing, and premium craftsmanship, makes them an excellent partner for expatriates seeking a distinctive, culturally integrated home in the capital.
