Built with volcanic aggregate blocks and enveloped by a glazed greenhouse, the restaurant offers panoramic views of the surrounding landscape while integrating bioclimatic design principles to enhance the dining experience.
5 key facts about this project
01
Volcanic aggregate blocks are used for structural thermal mass.
02
A glazed greenhouse surrounds the core, enhancing natural light.
03
Positioned to maximize views of the lake and volcano.
04
Partially buried on the north side to minimize visual impact.
05
Two-level layout separates multipurpose and dining areas.

The restaurant is situated to the north of a lake and a volcano, creating a strong connection to the natural surroundings. Its elevated position offers expansive views for diners, enhancing their experience with a backdrop of iconic landscapes. The design draws inspiration from the nearby volcano, featuring concentric circular forms that resemble its shape. At the heart of the restaurant is a solid core that serves as the main gathering space, surrounded by layers that accommodate various functions.

Architectural Concept

The building's concept is deeply rooted in the geological characteristics of the site. By reflecting the form of the volcano, the structure establishes a strong relationship between architecture and landscape. The central core serves as a focal point, while the surrounding layers create opportunities for different activities. This arrangement allows the space to be both functional and inviting, encouraging interaction with the environment.



Glazed Greenhouse

A notable feature is the glazed greenhouse that wraps around the core. This element facilitates a connection between indoor and outdoor spaces. It allows natural light to enter and helps with ventilation, contributing to the building’s sustainability. The greenhouse creates a link to the surrounding landscape, inviting the beauty of the outside in and enhancing the experience for visitors.



Materiality and Thermal Performance

Materials are essential to the design’s effectiveness. Volcanic aggregate blocks are chosen for their ability to store heat. This helps regulate the temperature inside the building throughout the year. Using this material reinforces the connection to the volcanic landscape, grounding the project in its unique setting while promoting energy efficiency.



Spatial Organization

The restaurant's layout spans two levels, with the multipurpose hall on the lower level and the dining area above. This arrangement maximizes scenic views while clearly separating service areas from guest spaces. The elevated dining area allows visitors to enjoy the impressive sights of the lake and volcano, making for a rich dining experience.

Large windows in the dining area frame views of the natural landscape and allow ample daylight to fill the space. This design choice enhances the atmosphere, creating a warm and welcoming environment for all who visit.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
