Rising from the landscape, the red spiral tower integrates multi-level terraces that enhance visitor interaction and observation of the surrounding countryside.
5 key facts about this project
01
The tower's continuous spiral design connects visually with the surrounding landscape.
02
Terraces at various heights provide comfortable viewing points for visitors.
03
The tapering profile enhances interaction among visitors on different levels.
04
Its vivid red color distinguishes it within the natural environment.
05
The structure encourages community engagement through shared observation experiences.

The Kurgi Observation Tower is located in the countryside, designed to provide visitors with a unique perspective of the natural surroundings. The structure is based on a continuous spiral form that gives the impression of rising from the ground. This connection to the landscape is an essential part of the design concept. The vibrant red color of the tower makes it stand out and adds to its role as a landmark, while serving a functional purpose for observation and exploration.

Architecture Concept

The design features a helix pattern with flattened areas at different heights, which create terraces for visitors. These terraces offer comfortable spaces to rest and enjoy the views without the strain of climbing continuous stairs. This arrangement allows for a varied experience as visitors move up through the tower, providing a welcoming environment for all.



Spatial Interaction

The tapering shape of the tower at its peak encourages interaction among visitors on various levels. This allows people to easily engage with others, creating a sense of community as they share the experience. Strategic openings and viewpoints enhance this interaction, enabling conversations and connections to form naturally as visitors explore the structure.



Visual Identity

Choosing red for the Kurgi Observation Tower plays a crucial role in defining its visual identity. The color gives the tower high visibility against the natural backdrop, drawing attention in a pleasing way. This contrast enriches the overall aesthetic, helping the tower to blend into the landscape while remaining a distinct feature.



Visitors can enjoy spacious terraces that highlight the changing scenery, allowing for a deeper connection with nature as they ascend through the tower.

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.
