Architect and Interior Design

About Us

Welcome to Behold Architect and Interior Design Co., Ltd. Established in 2014, we are a dynamic firm specializing in both architectural and interior design. Our expertise spans the entire design process, from starting point to detailed construction drawings and construction documentation. Throughout the construction phase, our role as the project’s designer extends to supporting all stakeholders until completion. With our team, owners can trust in our commitment to bringing designs to life in alignment with their vision and needs.

We hold the belief that architecture and interior design should seamlessly harmonize and reinforce one another. We nurture the connection between humans and the natural world, encompassing interactions with creatures, light, shadow, and diverse textures. Hence, we strive to encapsulate these emotions, tailoring them to each project’s distinctiveness. Our specialization lies in crafting designs that address human requirements, embracing simplicity, and quality of life. At Behold, our foundation is rooted in integrity and excellence.
