ABOUT

Interior Architecture 103 Co., Ltd. was established in April 1995, evolving from the in-house interior design department of Design 103 Ltd. As our team and scope of services expanded, the company grew into an independent practicewhile retaining the “103” as a reflection of our origins and long-standing design foundation.

Over 50 years of our experiences across a diverse range of projects in Bangkok and SEA, we have delivered comprehensive services including space planning, interior design, signage and wayfinding, construction management and supervision, as well as design-build solutions for small-scale projects.
Over the years, our perspective on design has continuously evolved. While creating spaces that express and elevate our clients’ brand identity remains fundamental, our approach today extends far beyond representation. We believe that interior architecture must respond to a broader set of responsibilities towards people, environment and future.
Our work integrates sustainability as a core design principle, from responsible material selection and waste-conscious detailing to designing flexible spaces that can adapt over time. We embrace inclusivity across generations and diverse identities, ensuring that every space is relevant, welcoming, and human-centered. At the same time, we are committed to delivering design solutions with a high level of technical precision and comprehensive detailing enabling effective cost control and supporting our clients in maintaining project budgets without compromising quality.
At its core, our objective is to deliver design that is not only aesthetically refined and functionally precise, but also conscious, adaptable, and enduringcreating meaningful value for our clients and the communities they serve.
