With its soaring skyscrapers and bustling shopping malls, downtown Sukhumvit often dazzles visitors with its ultra-modern flair. Yet tucked within this vibrant urban landscape are modern architectural gems that relate tales of Bangkok’s past.
Highlighting these often-overlooked masterpieces, the Siam Society recently organized a tour to showcase and celebrate their unique contributions to Thailand's cultural heritage.

Organized by the Siamese Heritage Trust, the tour offered architecture enthusiasts an entirely new perspective on Sukhumvit, highlighting the district’s rich architectural heritage and the urgency of conserving mid-century structures before they fade away.
Led by Navamintr Vitayakul, a former Siam Society Council member and Chomchon Fusinpaiboon from Faculty of Architecture at Chulalongkorn University, the tour underscores the Trust’s commitment to raising awareness about preserving modern architecture in Thailand, honoring those who safeguard these treasures of the recent past.
The journey commenced at the Siam Society Auditorium, a striking building designed by Edward Healey in 1933.
This modest yet elegant structure blends traditional teak wood with modern design, embodying a seamless combination of form and function.
The auditorium stands as a testament to Siamese culture, reflecting the Society’s mission to foster cultural dialogue through knowledge sharing.
Next on the itinerary was Wattana Wittaya Academy, Thailand’s pioneering girls' school, founded by American missionaries in the 1920s.

Its neo-classical buildings, featuring expansive verandas and steep roofs, were thoughtfully adapted to Bangkok’s tropical climate, creating a legacy of educational excellence.
A special treat awaited the participants as they gained rare access to the school museum, typically reserved for alumni or visitors with permits.
Inside, vintage student desks, lockers, and other artifacts offered a glimpse into the daily life at this historic institution.
Adjacent to the academy lies Wattana Church, designed by Dr. Amos T. Chang and completed in 1959. The church, with its serene cross-shaped layout and graceful wooden ceiling, originally relocated from Wang Lang to better serve the local community, has become a cherished gathering place.
The church tour also shed light on ongoing preservation efforts, showing how the structure has adapted to modern needs while retaining its architectural integrity.
Once an open-air space, it is now air-conditioned to combat the challenges posed by rising temperatures and encroachment of nearby skyscrapers.
As the tour progressed, the group visited the Embassy of the Republic of India, completed in 1979.
Designed by architect ML Tridhosyuth Devakul, this late-modern structure boasts a geometric design adorned with interlocking concrete brise-soleils, which serve to deflect sunlight and keep the interiors cool.
While some may view its shape as reminiscent of a water droplet, the design actually pays homage to India’s national bird—the peacock. Framed by a lush banyan tree, the embassy’s sharp lines are softened by the surrounding greenery.
Continuing their architectural journey, the group arrived at the Ambassador Hotel, a remarkable project completed in 1979 by Dan Wongprasat.

This harmonious blend of modern design and natural elements not only enhances the guest experience but also celebrates Bangkok’s lush landscape.
Among the tour’s highlights was the Miami Hotel, a mid-century gem that first opened its doors in 1965. With its pastel terrazzo floors, geometric brise-soleil, and central courtyard, the Miami Hotel captures the charm of a bygone era.
While the rooms have been renovated to meet modern standards, the hotel’s exterior remains well-preserved, maintaining its distinctive charm.
Named after the city where Thailand's first Miss Universe was crowned, it became a popular retreat for American GIs on leave, embodying Bangkok’s international allure.
Now under the stewardship of Suphol Tansirichaiya, the hotel has undergone careful renovations that respect its vintage character while updating essential amenities.
“Modern architecture not only holds a unique charm but is particularly meaningful in a tropical country like Thailand,” Suphol remarked, emphasizing the functional beauty of features such as brise-soleils and fins that once helped reduce direct sunlight and improve ventilation when air-conditioning was a luxury few could afford.
“It features beautiful shade and shadows,” he added, noting that those who appreciate modern heritage are often architects, photographers, or professionals who understand its value.
However, the preservation of these structures faces challenges. Many mid-century buildings in central Bangkok are being razed, often deemed unworthy of conservation simply because they are not old enough to be classified as historical heritage.
The renovation cost for these modern heritage sites is often higher than replacing them with a modern structure that offers larger utility space, Suphol explained, highlighting the unfortunate reality that many architectural treasures are bulldozed in favor of profit-driven development.
To combat this trend, Suphol suggested awards and incentives, such as subsidies or tax rebates, to encourage owners to invest in preservation.
His own hotel received recognition from the Association of Siamese Architects in 2020 for its renovation that preserved its Modernist details—proof that with commitment and creativity, it’s possible to honor the past while embracing the future.
The final stop was the Embassy of Switzerland. It was a privilege to walk through the "three-finger" layout of the Swiss Embassy, guided by Ambassador Pedro Zwahlen.

Not only did the ambassador warmly welcome visitors, but he also provided an exclusive architectural tour, showcasing how this 1961 tropical modernist masterpiece was designed with climate resilience in mind—well before the urgency of climate change was widely recognized.
Contrary to the typical temperature-controlled buildings, much of the embassy is open-air, including the welcome area.
Its innovative layout features residence and office spaces separated by lush courtyards and ponds, constructed from floating planes, brick, wood, and glass. The façade, adorned with mosaic and majolica, proudly displays the coats of arms of Switzerland’s 26 cantons.
Thoughtfully designed for tropical climates, the embassy incorporates cross ventilation, extended overhangs, and water elements aligned with the sun’s path, creating an effective, fuel-free cooling system that harmonizes with the environment.
Some of these buildings have naturally evolved over time. While their exteriors remain reminiscent of a bygone era, subtle adjustments have been made to bring them into the present.
For example, air conditioning units now cool rooms that were once designed to breathe with natural airflow, while new materials fortify structures that have stood the test of time.
These changes are more than conveniences—they’re thoughtful enhancements that preserve the spirit of mid-century Modern design, blending seamlessly with each building’s original character.
Each structure on this architectural journey adds a vital piece to Sukhumvit’s rich tapestry, reminding us that behind every façade lies a story waiting to be told.
As participants absorbed the beauty and significance of these mid-century masterpieces, the hope remains that a broader public will develop a deeper appreciation for Bangkok’s architectural heritage, ensuring that these treasures endure for generations to come.
