The Kurgi Observation Tower (KOT) is located in the North Vidzeme Biosphere, designed to connect visitors with nature. The tower has a clear purpose: to offer unique viewpoints for observing the landscape. Its design encourages accessibility, making it easy for people to move from the parking area to the tower and engage with the natural surroundings.

Design Concept

The tower consists of several four-sided stair runs, which are set at different angles on each level. This layout creates varied viewpoints for visitors as they ascend, allowing them to see the landscape from different heights. Each step up brings a new perspective, adding to the sense of exploration and curiosity.



Observation Points

At the top of the tower, there are four observation points that stand as ideal spots for taking in the views. These areas invite visitors to stop and appreciate the scenery around them. Such a design not only enhances the aesthetic experience but also helps create a meaningful engagement with the environment.



Materiality

Transparency is a key aspect of the design, achieved through careful material selection. The tower features layers of perforated steel plate and glass, which help to blur the lines between the structure and the landscape. This approach enables an open view for visitors, allowing them to feel connected to their surroundings while experiencing the architecture itself.



Structural Integration

The tower is anchored by an earthen base that contrasts with the lighter materials above. This relationship between heavy and light elements helps ground the structure in its rural setting. At the very top, a thatched cladding element provides shelter from the weather, ensuring visitors are comfortable without losing the sense of being outdoors. The design details encourage visitors to engage with both the architecture and the landscape, creating a harmonious experience.

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.
