and architecture practice.

About us

Founded by Long Tran, o9 Design Studio is a Ho Chi Minh City-based studio specialising in interior design and architecture for the hospitality industry. We combine comprehensive knowledge with human understanding to create thoughtful and engaging spatial experiences. Perfection is our passion and quality is our drive. We always aim to tailor our client’s visions into exclusive design solutions that are compelling, timeless & cost-effective.


Taking inspiration from contemporary life, o9 Design studio creates designs that respond to the context and narrative of each project. We embrace spatial aesthetic and user experience equally to foster complete sensory experiences.


We are both research based and creativity focused; each and every design decision reflects our firm belief in the dynamic interaction between experience, elements, form and lighting; rather than conforming to a formulaic style. As a result, we always try to explore new ways of thinking for each project to create works that resonate.
