Cantilevered forms of Corten steel extend gracefully over Iceland's unique geological landscape, creating a Visitor Center that both educates and connects visitors with the striking natural environment.
5 key facts about this project
01
Cantilevered design allows for unobstructed views of the surrounding geology.
02
Corten steel develops a protective rust layer, ensuring durability against harsh weather.
03
Shou sugi ban cladding enhances interior warmth while improving material resistance.
04
Rainwater harvesting system provides treated water for visitor use and promotes sustainability.
05
Photovoltaic panels combined with battery storage support energy needs year-round.

The Visitor Center at Grjótagjá is located in a unique geological area of Iceland, combining architectural design with the natural environment. It serves as a space for visitors to explore and learn about the remarkable rock formations in the region. The overall design concept emphasizes educational experiences and promotes interaction with the landscape, while the building itself extends out toward the ravine, creating a balance between built form and nature.

Materials and Form

Corten steel is a primary material used in the construction, known for its strength and durability in harsh weather. This material develops a protective layer of rust that not only increases its lifespan but also allows it to blend in with the rugged surroundings. The design features sharp edges and clean lines, which guide visitors toward important geological sites like Karlagjá and Kvennagjá. The cantilevered design gives the center a lightweight appearance, ensuring it complements rather than overshadows the landscape.

Spatial Organization

The center consists of two distinct levels: the lower level includes a ramp with an interior space and a lower platform, while the upper level functions as a viewing platform. This layout supports smooth movement throughout the building and offers various viewpoints of the surrounding geological features. By positioning the center between the viewing caves, it effectively separates the different areas, creating a clear distinction between those meant for viewing and those meant for bathing.

Sustainability Measures

Sustainability is an important focus of the design. Photovoltaic panels installed on the roof provide electricity to the center, with battery storage to ensure energy is available even in less favorable weather. The design also incorporates a system for rainwater collection, allowing rain to be captured and treated for drinking. These sustainable features reflect a commitment to minimizing the ecological impact of the building while educating visitors about the local environment.

Interior Detail

Inside the Visitor Center, shou sugi ban cladding is used, providing a warm and textured contrast to the exterior Corten steel. This technique not only enhances the aesthetic appeal but also improves the wood's resilience against the elements. Natural light entering through carefully positioned openings interacts with the textures, creating a welcoming atmosphere for visitors. The thoughtful use of materials and light enhances the overall experience within this carefully designed space.

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.
