Sinuous white walls and undulating glazing create a smooth balance between solid and void in a cafe in Chonburi, Thailand. 

Named Uncloud Coffee, the project, designed by Bangkok-based firm Unknown Surface Studio, is a cafe where undulating volumes form a beautiful backdrop against the magnificent view and the main function is to arouse curiosity.

The project is strategically situated on Khao Lam Road in Chonburi Province, and occupying a sharply triangular site adjacent to the main thoroughfare leading from Bang Saen, with majestic mountain views forming a stunning backdrop. 

For the design, the architects are inspired by the spectral allure of the Aurora Borealis, and abstractly interpreting these atmospheric light displays.

The architectural plan takes advantage of the triangular shape of the site and extends the building along the roadside in three main areas: a welcoming main entrance that combines a bar and seating area, an outdoor lounge encapsulated within a verdant courtyard, and a tranquil internal area for seating and client workspaces.

"The building’s form echoes the dynamic, sweeping patterns of the northern lights, with its structure gracefully arching along the roadway, melding effortlessly with its environment," said Unknown Surface Studio. 

"The design introduces uninterrupted, sinuous lines that connect all spaces internally and externally, fostering a cohesive architectural journey," the studio added.

Since the project is located close to the road, it is designed with principles that address noise and thermal comfort. For this reason, the architects have employed the facade facing the street as towering volume. 

The team has added the curved barriers that selectively open at strategic angles, maximizing mountain views while minimizing noise and heat from the street. 

"This setup not only reduces auditory disturbances but also helps in maintaining a cooler interior climate," added the office.

The courtyard forms a key part of the café, being naturally lit throughout the day and deliberately positioned to direct daylight and sky views into the building unobstructed.

Additionally, the integration of landscape and hardscape elements mimics architectural flow with its curved forms. The architects strategically positioned large trees around the building to act as a natural sound barrier and provide shade. 

The large trees are seamlessly blending the structure with its surroundings.
