5 key facts about this project
01
Constructed using locally sourced timber, enhancing sustainability and regional identity.
02
Features a spiraling design that provides uninterrupted views of the surrounding wetlands.
03
The roof is made from traditional thatch, integrating with the local landscape and culture.
04
Elevated structure reduces ecological impact on the sensitive wetland habitat.
05
Incorporates perforated steel elements for drainage while maintaining visual connectivity.

**Project Overview**
Located within the Pape Nature Reserve in Latvia, Ligzda exemplifies a design that integrates ecological awareness with cultural heritage. The structure serves as an observation point for local wildlife and emphasizes the significance of the area’s natural and cultural narratives. Drawing on the local vernacular, the design adopts elements from traditional hayricks, combining contemporary and traditional architectural principles to create a meaningful connection between inhabitants and their environment.

**Spatial Dynamics**
Ligzda’s spiraling form rises from the landscape, allowing visitors to ascend gradually and engage closely with the surrounding wetlands and avian habitats. An observation deck at a height of 7.35 meters offers panoramic views, enhancing the birdwatching experience while maintaining a sensitive relationship with the ecosystem. The wooden support poles reflect local construction methods and underscore the importance of harmony with the natural surroundings.

**Material Choices**
The project prioritizes the use of locally sourced materials, emphasizing sustainability. Natural solid wood poles provide structural integrity, while thatch roofing made from local reeds establishes visual continuity with the landscape. Galvanized steel elements, including the spiral staircase and decking, add durability, further enhanced by the use of perforated sheet steel for rainwater drainage. Each material choice is deliberate, reinforcing the project's ecological and cultural commitments while ensuring resilience against environmental elements.

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.
