5 key facts about this project
01
Potted coffee plants are integrated throughout the café, enhancing the overall experience.
02
The building features a multi-slope roof design that mimics local volcanic formations.
03
Cross-laminated timber construction promotes sustainability and reduces carbon footprint.
04

05
The museum area adopts a minimalist design to focus attention on volcanic exhibitions.

JLava is a coffee shop located at the foot of Hverfjall volcano in Iceland, combining coffee culture with the powerful character of its environment. The design focuses on the interplay between the building and its natural surroundings, creating a space that serves both coffee and educational displays about the local geology. Visitors experience a strong connection to the volcanic landscape while enjoying a casual atmosphere.

Architectural Concept

The design of JLava is inspired by the active volcanic landscape around it. Features include irregular shapes and a series of linked modules that resemble traditional Icelandic peat houses. This choice reflects a commitment to local architecture while presenting a modern twist. The roof has multiple slopes, echoing the natural lines of the terrain and enhancing the relationship between the structure and the landscape.



Materials and Sustainability

The building incorporates Cross-Laminated Timber (CLT) for its structural components, highlighting a focus on sustainability. This material choice supports an eco-friendly approach while creating a warm, inviting space. Additionally, the use of ecological cellulose insulation improves energy efficiency, contributing to a comfortable indoor environment without sacrificing environmental responsibility.



Interior Design Elements

Inside, the café area features many potted coffee plants, immersing guests in the coffee experience. This greenery not only beautifies the space but also encourages a climate of connection with nature. In contrast, the museum area adopts a minimalist appearance, guiding attention toward the volcanic exhibition and providing educational insights about the geological history of the region.



Design Features

A significant detail is the fire pit located at the entrance. It serves as a gathering spot for visitors, enhancing outdoor interaction and fostering a sense of community. The combination of dark wood on the exterior with the lively green of the plants creates a balanced visual appeal. The design effectively emphasizes the relationship between the structure and the natural volcanic landscape, inviting exploration and engagement.

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.
