ABOUT US

Greetings. We would like to introduce our small design office, passionate about architecture, located in Bangkok, a vibrant city in Thailand. Despite its size, Bangkok is home to numerous world-renowned landscape architecture firms.

Our office, though small, has a background in architectural and interior design before transitioning solely to landscape architecture. This shift stems from our growing interest in addressing larger-scale national and international issues, particularly those concerning sustainability and environmental impact. We aim to enhance the quality of life through designs informed by urban theories, reflecting our deep-seated commitment. Naturally, we prioritize designs that celebrate local culture and stimulate economic growth.

Our team's foundation was built through our shared experiences at a Hong Kong-based firm, where we honed our skills in large-scale, mixed-use projects. This experience instilled in us a profound understanding of urban development beyond mere aesthetics, encompassing significant urban-scale considerations such as water management, exemplified by projects like Sponge Cities and Smart Cities in mainland China. We are deeply grateful to William, the firm's owner, and Michael, our project manager, as well as April, Yuan Yuan, Shirley, and other invaluable individuals, who acted as our invaluable back-of-house team, providing guidance and opportunities. We extend our sincere thanks to SED+ for their support.

After years of collaboration, we decided to return to our homeland and establish this small landscape architecture office, while continuing to collaborate with SED+ in a back-of-house capacity, eager to apply our knowledge and skills to projects where we can integrate meaningful concepts for the benefit of the government and our clients. We aspire to contribute to the creation of more innovative and sustainable public spaces worldwide.

Thank you for your interest and for giving our small office this opportunity."
