The Vogafjos greenhouse resort is located in the dramatic landscape of Iceland, near Hverfjall Volcano. It combines several functions, including a restaurant, accommodation, and a greenhouse for growing food. The overall design aims to connect closely with the surrounding nature, using a flowing form that reflects the patterns of the landscape.

Functions and Layout

The resort features a thoughtful arrangement of spaces that enhance its practical use. Key areas include Greenhouse 1, which spans 1,900 square meters, a dining area of 330 square meters, and a multipurpose hall measuring 270 square meters. An additional greenhouse designated for reservations is 1,500 square meters. The project also includes three Greenhouse Cabins, totaling 300 square meters, which offer a unique experience by integrating living spaces with agricultural functions.

Material Choices

Sustainability plays a crucial role in the selection of materials. The main structure is made from cross-laminated timber, which is sourced from local forests. This choice supports the local economy and minimizes transportation emissions. Local lava rocks are used for the exterior walls, creating a connection to the volcanic landscape. The roof employs polycarbonate panels, allowing natural light to enter while providing good thermal insulation for energy efficiency.

Innovative Design Features

Each Greenhouse Cabin is designed to host up to five people, providing guests an immersive experience in a living greenhouse. This unique feature enables the cultivation of fresh produce, reinforcing the idea of self-sufficiency. The facade showcases a pattern inspired by frost flowers, which not only adds visual interest but also interacts uniquely with light throughout the day.

The integration of these elements results in a building that closely connects with its environment. Guests can enjoy expansive views while experiencing a functional space that underscores the beauty and complexity of Icelandic nature.

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.
