5 key facts about this project
01
The design incorporates observation decks positioned at varying heights for diverse viewing experiences.
02
Precast concrete panels are used to enhance structural integrity while allowing for efficient construction.
03

The INTERSTICE: THE CAVE TOWER is designed to blend with its surroundings while offering engaging experiences for visitors. Located in a landscape marked by geological features, it acts as a gateway to Kvennagja and Karlagja caves. The overall concept revolves around harmonizing built spaces with nature, encouraging exploration and interaction among visitors.

Site Layout

The layout includes several important areas such as entrances to Kvennagja and Karlagja caves, areas for visitors to rest, and gathering decks. This careful arrangement promotes an easy flow of movement, allowing visitors to navigate through different functional spaces smoothly. Public walkways connect these areas, making them accessible and enhancing the experience through various visual and spatial connections.

Architectural Form

The cave tower showcases distinctive geometric shapes that relate to the natural landscape. These forms create varied viewing experiences and highlight the contrast between the building and its surroundings. Observation decks are thoughtfully placed at different heights, allowing visitors to appreciate the landscape from multiple angles, encouraging deeper connections to the natural environment.

Material Considerations

The construction incorporates specific materials that support the design while ensuring functionality. Insulated glazing units with two panes filled with argon improve energy efficiency and comfort. Precast concrete panels add stability and facilitate faster construction. Heavy metal framing ensures durability, while vapor barriers and waterproofing layers protect the structure from environmental factors.

Functional Spaces

Inside the tower, spaces are designed to meet a variety of visitor needs. Areas for ticketing, visitor information, and rest are integrated smoothly. Exhibition and display spaces provide educational opportunities, while a café and gift shop create welcoming places for social interaction. This mix of functions helps visitors engage fully with what the site has to offer.

The observation deck provides wide views of the landscape, allowing visitors to connect with their surroundings. It encourages contemplation and appreciation of the geological features, making the visit memorable.

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.
