The Pavilion, located near the ancient caves of Grjótagjá in Iceland, exemplifies a thoughtful connection between architecture and the surrounding landscape. It serves multiple purposes, including a cinema, a bar/restaurant, and an exposition center. The design focuses on blending with nature, aiming to minimize environmental impact while providing a welcoming space for visitors.

Site Integration

The form of the Pavilion rises gently from the ground, resembling a protective cape. This elevated design minimizes disruption to the natural surroundings and preserves the scenic beauty of the area. The building aligns itself with the contours of the nearby volcano, creating a visual dialogue with the landscape that enhances its overall presence.

Functional Layout

Inside, the Pavilion is organized into three main areas that encourage movement and interaction. The cinema acts as the central feature with walls designed to reflect themes of rock and ice. This unique shape not only adds a distinct character but also improves sound quality within the space. Adjacent to the cinema, the bar and restaurant connect through a long, glazed corridor. This transparent passage allows people to flow easily between different areas while fostering a sense of community.

Sustainability Strategies

Sustainability is a key consideration in the design, prominently featuring a green roof that contributes to energy efficiency. The choice of low-carbon concrete and wood aligns with the goal of reducing the project’s environmental footprint. Strategic roof openings are designed to maximize natural light coming in from the south, reducing reliance on artificial lighting and creating a bright, inviting atmosphere inside.

Design Details

The Pavilion is notable for its careful attention to practical details. The fully glazed foyer encourages visitors to explore both the interior and the natural beauty outside. Natural light filters in, enhancing the experience within the space. The combination of thoughtful design, material choices, and a layout that invites interaction distinguishes the Pavilion as a meaningful addition to its environment, reflecting a commitment to harmony with 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.
