Subscribers only
Constructed with cross-laminated timber and a green roof, the facility harmonizes with its geothermal surroundings while serving as a café and spa for visitors to enjoy unique views of Lake Myvatn.
5 key facts about this project
01
Designed to blend into the landscape with a green roof that supports local biodiversity.
02
Utilizes local volcanic stone for structural elements, connecting the building to its geological context.
03
Features large arched openings that enhance natural light and connectivity with the surrounding scenery.
04
Employs geothermal heating systems, maximizing energy efficiency and environmental sustainability.
05
Incorporates cross-laminated timber panels for rapid construction and a lightweight design.

### Project Overview
Located near Lake Myvatn, the café and spa is designed to integrate with the surrounding landscape, prioritizing environmental responsiveness while providing modern amenities. The intention is to create a space that enhances visitor experience through its connection to the natural environment, featuring expansive views of the lake.

### Spatial Strategy
The architectural layout is characterized by a structure partially embedded in the earth, which minimizes visual impact and enhances thermal performance. A series of gabled roofs, adorned with green vegetation, reflect traditional Icelandic design while improving insulation. Beneath this upper section, a base constructed from locally sourced volcanic stone contrasts with timber elements, establishing durability and a strong connection to regional geology. The overall massing is calibrated to support natural ventilation and solar gain, promoting a comfortable environment throughout the year.

### Material Selection
The project emphasizes the use of sustainable, locally sourced materials that complement its aesthetic and functional goals. Features include a green roof for biodiversity and insulation, cross-laminated timber (CLT) for structural integrity and lightweight properties, and textured concrete for entrance elements, all contributing to a cohesive design. Interior spaces incorporate natural finishes and earthy tones to foster a calming atmosphere, while durable terrazzo flooring ensures practicality in high-traffic areas. The integration of these materials supports a structure that is both visually appealing and environmentally responsible.

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.
