5 key facts about this project

05
Universal access is ensured through a gentle ramp at the entrance.

Koka Bāka, meaning "wooden beacon," is a tower that stands out in its landscape. With its unique cantilevered top floor, the design allows for wide views of the surrounding area. The building invites visitors to experience nature while providing a feeling of openness. Full-height sliding doors on three sides of the upper level connect the interior with the outdoors, fostering interaction with the environment.

Structure and Materials

The tower’s framework includes 200x200mm pre-rusted cortensteel columns and beams, creating a solid base. This combination offers stability while allowing the design to reach impressive heights. Trusses support the cantilevered top floor, emphasizing both structural integrity and aesthetic appeal. Together, these elements make the tower a practical yet visually interesting structure.

Core Design and Accessibility

In the center of Koka Bāka is a void space that acts as a quiet area for visitors. Here, horizontal hammock nets provide a place to rest and reflect. The walls feature numerous perforated openings, allowing light and air to flow freely inside. A gentle ramp leads to the base of the tower, making it accessible for everyone and creating a friendly atmosphere as people ascend.

Circulation and Cladding

Moving through the tower is an engaging experience thanks to the winding staircases that change direction partway up. This variation keeps the journey interesting. The outer wall serves as a railing, with additional safety features where necessary. Vertical untreated pinewood slats are used for cladding the structure. These slats are spaced to provide views while ensuring safety. As the wood ages, it helps the tower blend better into its natural surroundings.

Environmental Orientation

The tower is positioned to align with the four cardinal directions. This setup creates a connection with the landscape, and the cantilevered top appears to point toward the Kurgi farm, establishing a visual link with the open area. At night, the tower is lit in a way that highlights the base and horizontal openings. This creates a beacon-like effect, drawing attention to the structure in its setting. The interplay of light and shadow adds further depth, making the building noteworthy both day and night.

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.
