About the team

Students and faculty members of Chalmers Architecture & Civil Engineering Department (ACE) are participating in SDE21 as Team Sweden with the project C-Hive. C-Hive is a platform for the research that is done at Chalmers and the project will connect to and draw on current ongoing research projects that focus on additive manufacturing, circular kitchens, as well as co-living and co-working.

Our motivation

Today half of the global population live in cities and the UN World Urbanization Prospects estimates that in 2050 two thirds of the population will be concentrated in urban areas. We see this increase of population as an opportunity to create innovative housing solutions that contribute to the ecological, economical and social development of cities. A denser city requires that we rethink our lifestyles and how we use and live in buildings.

Due to the rapid changes in our living and working situations, our environments have not had the time or the capacity to adapt. As we need to change our living arrangements to accompany and improve our lives, living-working spaces, as public/ private interfaces around kitchen and living areas, are a potential solution for healthier, more sustainable, and contemporary equitable and just architecture.

The main focus for C-Hive is to develop cellulose-based additive manufacturing, while being a platform to support research at Chalmers on co-living situations and flexibility. Our goal is to create a building typology that mixes co-living and co-working spaces using innovative solutions to tackle the environmental and societal challenges of urban living of both today and tomorrow.

Our motivation

Project description

Team Sweden is interested in exploring how live/work spaces can form a public/private interface around the kitchen and living areas. Thus, as we are witnessing a rise in loneliness-induced disorders in cities, everyday interaction and sharing experiences would help people from different backgrounds reconnect. The corollary would allow for mixed use of spaces, mixing public and private, and help a human scale urban environment to develop. Finally, as we are observing rising prices on the housing market, this dynamic living arrangement we are striving for shall propose a more accurate and optimised use of space.

Today the addition of stories is often found in residential and office buildings. In urban areas, warehouses and old factory buildings are also being extended more and more frequently. The diversity of use revives the urban space. Rooftop extensions ultimately can not only form a public luxury, but also create a platform for intensive solar energy utilization.

The C-Hive co-live/work unit will be constructed using lightweight cellulose-based 3D-printed elements allowing for urban densification by integrating the unit on the rooftops of existing buildings. The C-Hive plus energy solar unit will become the world’s first building to use a cellulose based additive manufacturing system.

With C-Hive we are proposing to build on top of the existing building stock. This method reclaims the unused city spaces and opens up the roof for public use. Sweden has a large low-density housing stock of 3-5 story buildings from the 1960’s and the 1970’s. Today many of these projects are being upgraded with added stories. Building on top of existing structures comes with challenges such as weight limitations, additional infrastructure and disruption and nuisance for existing tenants caused by construction.

To tackle these restrictions C-Hive will be constructed with timber construction combined with a cellulose-based 3D-printing system using additive manufacturing. This would allow the construction of rooftop additions to be lightweight and cause minimum disruption whilst using a fully recyclable renewable resource which is a waste product of the Swedish forestry industry.
