5 key facts about this project
01
Rammed earth structure enhances thermal performance and connects to local building traditions.
02
Lighting-integrated concrete caps provide dual functionality for aesthetics and illumination.
03

05
Exhibition corridors promote fluid visitor movement and engagement with surrounding nature.

The pavilion in Shinshu Sky Park, Nagoya, Japan, provides an architectural response to the seasonal flower festivals celebrated in the region. Designed to rise upwards, it symbolizes growth and a connection to nature. The structure serves as both a gathering space and an exhibition area, inviting visitors to engage with the beauty of the landscape surrounding it.

Interior Elements

The pavilion features various interior elements that support its function and aesthetics. Lighting-integrated concrete caps provide efficient illumination while also serving a structural purpose. This combination of functionality enhances the atmosphere inside the pavilion and contributes to its overall design.

Structural Design

Pre-fabricated earth shell components are utilized to create a sustainable and efficient structure. These components are secured with concrete bridges, which enhance stability and allow for creative use of space. The structural design reflects an understanding of both the physical requirements of the building and the conceptual aims of the project.

Circulation and Layout

The layout emphasizes visitor circulation, with designated exhibition corridors that facilitate smooth movement through the space. A pre-fab rising walkway adds to accessibility, encouraging interaction with the various exhibits. This thoughtful arrangement ensures that visitors can fully appreciate the offerings of the pavilion.

Foundation Specifications

The foundation is designed for durability, featuring a 200mm slab-on-grade with surface footings. It is complemented by 100mm of sand that conceals the footings and a 600mm sand/gravel foundation bed to provide stability. These construction details show a commitment to building in harmony with the environmental conditions of the site.

The pavilion effectively blends interior and exterior spaces, fostering a connection to the natural environment while creating an opportunity for cultural engagement. It stands as a thoughtful addition to Shinshu Sky Park, enhancing the experience 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.
