What if architecture, informed by scientific inquiry and imagination, could redefine our understanding of the built world? Founded by Chris Bosse, Alexander Rieck, and Tobias Wallisser, LAVA is a laboratory network that explores and innovates through architecture.
Since its inception in 2007, LAVA has evolved into a global network that spans cultures and disciplines, with studios in Berlin, Ho Chi Minh, Stuttgart, and Sydney. In an era of technological disruption and environmental flux, we leverage advanced digital tools, speculative thought, research, and knowledge from many regions and customs to address complex architectural spaces with resource efficiency.
Embracing a symbiotic philosophy and an integrative vision of life, LAVA recognizes the human habitat as an extension of the landscape that considers its larger ecological conditions. This ethos fosters the design of synergetic spaces that nurture well-being and meaningful interaction—spaces that inspire harmony, creativity, and a sense of community.
Our design process engages with contemporary challenges, revealing architecture's ability to respond to the 'flowing lava' of spatial and social intricacies. By reconciling human needs with environmental imperatives, LAVA co-shapes the dynamic ecosystems of a planet striving for balance. To us, every building is an opportunity to recast architecture as a culture that inspires the evolution of a built environment that is both progressive and enduring.

B is the sum of four studio divisions called B-architecten, B-bis, B-city and B-juxta. At B-architecten, we design sustainable buildings that enhance both the urban and the open space.
Back in 1997, Evert Crols, Dirk Engelen and Sven Grooten set up an independent office for architecture: B-architecten was born. The three had met during their education in Antwerp and Amsterdam. At the internationally oriented Berlage Institute, it became clear that Evert, Dirk and Sven shared a common design interest. Today, the office is located in Antwerp and Brussels.
Ten years after the foundation of B-architecten, they started a new initiative together with Sebastiaan Leroy: B-bis architecten became an office that focuses on small architectural projects, residential interior design, offices and shops, scenographies for exhibitions and performing arts, temporary installations and furniture design.
In 2020, B-city was launched as a third B-platform with the aim to shape and supervise complex urban projects. The core of its ambition is to work on large-scale projects that carry the potential of becoming new city districts.
Today, B-architecten, B-bis and B-city have naturally grown into an office of more than 60 people. Each B-team has its particular focus and way of functioning, yet they all share a distinct innovative view on the variety of projects the B-platforms stand for.
