bambubuild sculpts a complex, bamboo restaurant in vietnam

bambubuild translates natural forms into modern design

In the heart of Long Thành, a growing district in rural Vietnam, the newly constructed Keeng Seafood Restaurant exemplifies BambuBuild‘s innovative architecture and construction skills. Recognized at once by its dramatic and intricate bamboo structure topped by a boat-shaped thatched roof, the project introduces a visual landmark within the evolving urban landscape. Supported by bamboo structures reminiscent of nipa palms — a familiar riverside plant in southern Vietnam — the design integrates traditional elements from the natural context with modern design.

The architects at BambuBuild faced a unique challenge in the design of the Keeng Seafood Restaurant — to create a sculptural work of architecture while adhering to environmentally-friendly principles and efficient construction. The ground floor plan of the bamboo hall, accommodating up to 180 guests, lends simplicity in design, strategic accessibility, and a fluid connection with the adjacent annex house.

Responding to the owner’s mandate for an impressive and eco-conscious structure, BambuBuild embraced bamboo as both a structural and decorative component. The use of ‘solid bamboo,’ which the team refers to as ‘iron bamboo,’ highlighted its stiffness and strength, making it an ideal choice for construction. Traditional bamboo poles transformed into posts, beams, and trusses, forming a hyperbolic paraboloid surface — a doubly-curved structure renowned for its structural efficiency and aesthetic qualities.

The thatched hyperbolic paraboloid roof

The bamboo hall is shaped by BambuBuild’s innovative use of hyperbolic paraboloid surfaces as ceilings and columns. Interconnected and interlocked, these elements allow the roof to extend up to an impressive four meters (thirteen feet) at the gable. The doubly-curved and doubly-ruled nature of these surfaces, easily constructed from straight bamboo poles, facilitated an efficient construction process. The double curvature of the hyperbolic paraboloid posed a challenge in roofing with natural thatch due to its convex and concave forms. The architects addressed this issue by incorporating trusses and purlins on the concave side, creating a simple sloped roof. This two-layer structural roof both solved the roofing dilemma while to the visual allure of the ceiling.
