Benjakitti Forest Park

June 19, 2023

How does one retain a historical urban asset while making it relevant to present-day conditions and context?

Arsomsilp Community and Environmental Architect Co., Ltd. took up the task of converting Bangkok’s crown gem of a park—one that was established for Her Majesty Queen Sirikit—into a thriving public treasure that contributes its ecological and hydrological functions to the betterment of the urban landscape.


The design concepts were firstly developed to follow Her Majesty’s visions to improve public understanding and knowledge about ecology, forest, hydrology, and the environment. Secondly, the project seeks to be a pioneer in developing ecological parks. Lastly, the park aims to serve the urban communities and preserve the ecological environment of the city, one that is able to retain 128,000 cubic metres of water during the rainy season and produce 1,600 cubic metres of clean water per day.

• Strategy 1: Solutions for the monsoon climate
• Strategy 2: Natural solutions for water treatment
• Strategy 3: Preserve existing trees
• Strategy 4: Reuse and recycle
• Strategy 5: Long-term low maintenance
• Strategy 6: Urban accessibility
• Strategy 7: Ecological forest park
• Strategy 8: Recreational facilities and places for people
