The Kurgi Observation Tower is located in the North Vidzeme Biosphere Reserve, along the border between Latvia and Estonia. This tower serves to enhance the visitor experience while encouraging a deeper connection with the natural environment and the region's equestrian culture. Its design takes inspiration from the shape of a pine tree, featuring a helix structure that blends with the surrounding landscape. The focus is on providing expansive views of the biosphere while maintaining a close relationship with nature.

Initial Floor Functionality

On the first floor, practical elements take center stage. This level includes facilities for visitor briefings, storage, and toilets, along with areas for observing horse training. It serves as an essential starting point, guiding visitors in understanding the farm's activities and the region's unique equestrian heritage.

Engaging Observation Levels

The second floor enhances visitor engagement with the local farm activities, allowing for direct observation and interaction. As guests move to the third floor, they reach the height of the surrounding tree line. This elevation offers beautiful views for those who come to enjoy the quiet moments of sunrise and sunset, highlighting the connection between the structure and its natural setting.

Panoramic Experiences

Ascending to the fourth floor, visitors are rewarded with views that extend beyond the nearby trees. Here, they can appreciate distant landmarks, including Tündre Lake and Holdre loss. The fifth floor features a glass-enclosed lounge that allows for unobstructed panoramic views while also providing a space for guests to purchase souvenirs from the farm.

Accessibility and Design Integration

The design strongly considers accessibility, incorporating ramps and elevators to ensure that everyone can enjoy the space. A double spiral staircase facilitates smooth movement between levels, adding to the overall experience. Each detail, from seating arrangements to viewing platforms, is thoughtfully included to encourage a connection with the environment and enhance visitors' enjoyment of the landscape.

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.
