With a transparent solar panel façade and an observation tower that offers panoramic views of the surrounding geological formations, the structure serves as a visitor center and recreational hub at the heart of a tectonic fault landscape.
5 key facts about this project
01
The tower is designed to integrate seamlessly with the surrounding geological features.
02
A gallery in the visitor center highlights the region's geological history and significance.
03
Transparent solar panels allow natural light while generating renewable energy for the building.
04
The green roof effectively filters rainwater, contributing to the site's sustainability.
05
Two bridges connect different sections, enhancing accessibility to geological formations.

The Iceland Cave Tower project is located near a tectonic fault, providing a unique opportunity to connect visitors with the geological landscape. Its design promotes exploration and interaction with the area while fulfilling various functions such as observation, education, and recreation. The overall aim is to integrate architecture with the natural environment, enhancing visitor engagement.

Observation Tower

The observation tower serves as the main feature of the design, featuring a glass observation window that offers expansive views of the geological structures around it. This window allows visitors to see and understand the tectonic plates while taking in the surrounding vistas. The tower encourages exploration and provides a place for quiet reflection, creating a powerful connection between people and nature.

Access and Pathways

The project includes two bridges that connect the northern and southern sections, along with a designated walking path in the eastern area. These routes are designed to facilitate movement across the site while guiding visitors to different geological highlights. By focusing on accessibility, the design respects the existing landscape, allowing guests to navigate through the rocky terrain without causing significant disruption.

Visitor Amenities

A pavilion enhances the visitor experience with essential amenities such as changing rooms, showers, and an instructor's area for those wanting to swim in Kvennagya cave. These facilities add comfort and convenience for guests. The visitor center also features a gallery that shares the geological and historical context of the area, providing educational opportunities that enrich the visit.

Sustainability Features

Sustainability is an important aspect of the project, as indicated by a green roof that filters rainwater. Additionally, transparent solar panels are incorporated into the building’s façade. These panels generate energy while allowing natural light to enter the interior spaces. This combination of sustainable technology and architectural design highlights a commitment to environmental responsibility.

The design of the Iceland Cave Tower connects visitors to the geological landscape, encouraging exploration and understanding of the natural environment. The careful integration of features and amenities enhances the experience, inviting ongoing curiosity and discovery.

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.
