Add concrete to the list of things graphene can improve. Scientists at the University of Exeter ‘s Center for Graphene Science developed a new technique to incorporate graphene in concrete production with the help of nanoengineering technology — and the resulting material was not only over twice as strong as concretes we have today, but “drastically reduced the carbon footprint of conventional concrete production methods.” Is there anything graphene can’t do? It can boost both the strength and durability of concrete. The resulting University of Exeter composite material is four times as water resistant as existing concretes, and, according to professor Monica Craciun , “by including graphene we can reduce the amount of materials required to make concrete by around 50 percent — leading to a significant reduction of 446 kilograms per tonne of the carbon emissions .” Related: MIT just discovered a way to mass produce graphene in long rolls The research, published in late April in the journal Advanced Functional Materials , pioneers a novel, low cost technique that is, according to the university, compatible with requirements for modern, large-scale manufacturing. The composite material can be utilized right on building sites. Craciun described the new green concrete as an absolute game-changer. She said its strength, durability, and water resistance make it “uniquely suitable for construction in areas which require maintenance work and are difficult to be accessed.” Lead author Dimitar Dimov, a PhD student at the university, described the research as a first but crucial step “in the right direction to make a more sustainable construction industry for the future.” He said in the statement, “Finding greener ways to build is a crucial step forward in reducing carbon emissions around the world and so help protect our environment as much as possible.” + University of Exeter + Advanced Functional Materials Images via Depositphotos and Derek Torsani on Unsplash

Japanese architect Makoto Suzuki has carved out a slice of live/work paradise with this cluster of cabins in Hokkaido . While each mono-pitched structure appears to stand independently, the timber-clad buildings are interconnected. The project, called the House in Tokiwa, also achieves harmony with the landscape through the use of natural materials and low-profile structures that embrace nature at every turn. Located near Sapporo, House in Tokiwa comprises a series of structures of varying heights clad in vertical timber planks. Mono-pitched roofs top the taller volumes, while greenery covers the roofs of a few of the lower-profile structures. Large windows frame views of the surroundings while the relatively remote location mitigates privacy concerns. Outdoor terraces also reinforce the connection with nature.

The main living areas are set in a cluster that wraps around a small courtyard planted with lilac trees. This cluster contains a two-story villa for Suzuki’s father, a kitchen and dining area with full-height windows, the master bedroom, and an office for Suzuki’s wife that sits above the living room. The majority of the workspaces are housed in the second cluster, which includes a meeting room, bathrooms, and two spacious work areas, one of which is used by sculptor Takenobu Igarashi . + Makoto Suzuki Via Dezeen Images via Koji Sakai
