P.L. Design Company Ltd., founded in 1991, has earned a reputation for innovative design service in site planning and landscape architecture in the Asian region. Due to growing environmental concerns, we put special emphasis on creating natural character that will enhance as well as conserve the environment.

Our experienced team approaches each project in a creative and sensitive manner addressing the needs and desires of the client.

We are aware of the importance of individuality in a design and therefore focus on a distinctive image based on location, climate, and social context of each proposal. We pride ourselves in our ability to balance design with the financial and maintenance requirements of the client.

We strongly believe that team work is the best method for solving issues and creating original design.


Our dedicated and experienced team with expertise in landscape, architecture and construction management, collaborate to develop innovative, practical and sustainable design solutions.
20 landscape architects, architects, landscape technicians and support staff drawn from regions all over Thailand—North, Northeast, Central and South—collaborate to develop the best design solutions for projects ranging from home gardens to large scale master planning with solid cultural and planting knowledge from all over the country.
