KVIKA is an innovative project that combines a restaurant with a greenhouse, located in the distinct climate of Iceland. The design focuses on promoting sustainable practices by integrating food cultivation directly into the dining experience. This approach allows diners to enjoy fresh produce while engaging with the process of its growth, highlighting the connection between nature and food.

Design Strategy

The project employs bioclimatic principles, aimed at optimizing the building's performance in a challenging environment. With temperatures averaging -0.5°C, careful consideration has been given to orientation and thermal control. Features such as large windows and natural ventilation enhance airflow and sunlight penetration, creating a comfortable atmosphere for both the greenhouse and restaurant areas.

Material Selection

Reinforced concrete is used for the walls and slabs, providing a solid structure that can withstand the harsh Icelandic weather. This choice is not only practical but also contributes to the longevity of the building. Alongside concrete, basaltic rock plays an important role in insulation and stability, helping to regulate temperatures throughout the year.

Landscape and Outdoor Engagement

A significant aspect of KVIKA is its roof garden, which elevates the overall experience. This green space adds beauty to the structure and serves as a habitat for local wildlife. It also acts as an outdoor dining area, allowing guests to connect with the surroundings while enjoying their meals. The design emphasizes a relationship between the built and natural environments, enhancing the sense of place.

Sustainability Integration

Throughout the project, a strong emphasis is placed on sustainability. By integrating agricultural practices into the urban landscape, the design serves as a practical example of how to combine food production with dining. The thoughtful arrangement of spaces allows for a direct experience of both cultivation and consumption. Above the restaurant, the roof garden provides a refreshing touch of greenery, bridging the gap between nature and the dining table.

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.
