The Bubbling Greenhouse Restaurant is located in a region rich in geothermal hot springs. It combines sustainable agriculture with a unique dining experience. The design consists of three main areas—Greenhouse, Events Hall, and Restaurant—each serving specific functions while contributing to a unified architectural style that reflects the organic shapes of springs.

Node Structure

Each of the three nodes has its distinct purpose. The Greenhouse Node focuses on hydroponic farming, allowing for the growth of plants without pesticides throughout the year. The arrangement of the nodes creates different heights and spatial experiences, encouraging visitors to explore the building while enjoying an immersive environment.

Sustainability Approach

Sustainability plays a key role in the design. The restaurant uses geothermal energy from the site to meet its power needs. A closed-loop system circulates a water-based antifreeze mixture through sealed pipes, providing efficient energy use without taking up too much space. This method illustrates a commitment to eco-friendly practices in the culinary landscape.

Landscape Integration

Outdoor areas are essential to the layout, offering visitors views of the surrounding landscape, including hot springs and volcanic features. Seating is arranged in triangular tent structures, promoting social interaction and providing a comfortable space to enjoy nature. This connection enhances the overall dining experience, allowing guests to feel part of the environment.

Structural Composition

The structure combines space truss systems with steel tree columns. This design offers solid support and visual interest, reflecting the organic shape of the building. These components work together to achieve the desired look while ensuring that the structure remains stable. Subtle details highlight the balance between functionality and visual appeal.
