Chiang Mai, Thailand

The history of American engagement in northern Thailand is a story of friendship and cooperation. It is a story of two great nations and the many people who have worked to make life better for generations of Thais and Americans.

Established in 1296 as the capital of the Kingdom of Lanna, Chiang Mai’s ancient history is vividly represented through the city’s streetscapes and buildings. The original brick walls that define the Old City’s perimeter are still visible and many extant historic wats—temples—display the area’s traditional architectural style. The mountains of Doi Suthep rise to the west of the city and are home to a sacred monastery. To the east, the city’s growth takes a more contemporary form with superhighways, office parks, and large-scale retail.

The new site joins the eastern expansion of the city, approximately 1¼ miles from the existing campus with easy access to the Chiang Mai Superhighway. The Consulate site abuts large scale retail on the north, low-scale residential on the south, and tree-lined streets with lively businesses and restaurants on the east. The team is creating a contemporary civic presence by addressing the different density of scales in this growing mixed-use district.

Developed in direct response to its humid, tropical climate, the local architectural vernacular provided lessons on how to create a sustainable, efficient project that is rooted in its surroundings. The team was inspired by the indoor/outdoor blending of public spaces and by the walled gardens, which present a protected view that widens dramatically upon entry. The city’s architectural legacy is a powerful influence, which the team is honoring throughout the new campus.

At the outset, the Department of State’s Bureau of Overseas Buildings Operations (OBO) gave the team a number of important goals:

Create a safe and functional facility for U.S. Consulate staff and visitors
Create an appropriate civic presence
Allow for future flexibility and growth
Create sustainable and resilient solutions specific to the site
Develop an architectural vocabulary that reflects the best of American values and culture while being sensitive to local culture, climate, and traditions

Traditional Northern Thai design layers public and private spaces, which the team applied in various ways to address the Consulate’s specific security and programmatic needs. Using Thai constructs, three primary architectural concepts were applied and developed into a distinctly contemporary site plan.

The New Consulate General Building in Chiang Mai is a contemporary, performance-driven interpretation of Northern Thailand’s rich design traditions. Lanna houses typically have a series of small private rooms that are elevated above the ground and organized around a chaan—the open terrace—that inspired the Consulate’s raised, open-air public space. Another intriguing tradition is modular façades that use smaller-scaled building components to create unique facade elements that are both utilitarian and ornamental. This efficient method inspired the perforated metal screens and louvers, which provide shade for many of the spaces within. Not only do screens and louvers add texture and depth to the façade, they also dramatically increase the building’s performance.

For much of the year, the heat and humidity in Chiang Mai are intense, but well-designed outdoor spaces can remain very comfortable with protection from the elements. Aluminum perforated screens and louvers shade the south-facing terrace, minimizing solar heat gain while controlling daylight. Robust digital analytics were utilized to study different louver configurations with the goal of reducing “red” hot spots, which fall outside of the human comfort zone.

The design for the New Consulate General Building in Chiang Mai will become a physical embodiment of the team’s goals: To create a resilient, high-performance, secure, and welcoming place that is responsive to its climate and respectful of its context, and in doing so, represents a renewed commitment to the long and valued diplomatic relationship between the United States and Thailand.
