CPH Common House First Upcycled High-Rise Building in the World
17,577 tons of waste can be upcycled to build the complex enabling to reduce carbon dioxide emissions by about 1,174 tons

Due to the Danish architecture firm TREDJE NATUR, their latest proposal CPH Common House is the first upcycled high-rise building in the world. Situated in the Ørestad area of Copenhagen, its designers Lendager Group and TREDJE NATUR aim to set totally new standards for sustainability. Incorporated circularity played a pivotal role right from the very beginning. With a total residential area of 21,000 square meters and 30,000 square meters of commercial space in the building’s base, topics like a well-thought-out microclimate, resource use and material recycling are core parts – instead of annoying trivialities – of the architectural concept.

”With CPH Common House, we want to show that you can easily build high and densely without losing the connection to history, context and the human scale. The project is based on a strong understanding of the site, resources and the microclimate, which results in an empathetic benchmark for sustainable high-rise buildings in Copenhagen,” said Ole Schrøder, partner at THIRD NATURE.

But why TREDJE NATUR calls CPH Common House the first upcycled high-rise building in the world? Due to the architects, 17,577 tons of waste can be upcycled to build the complex. This enables to reduce carbon dioxide emissions by about 1,174 tons and reuse resources like tiles, concrete, window frames or wood paneling to an unprecedented extent.

CPH Common House provides several recreation areas on the different roof stages and greenery-infused courtyard. According to TREDJE NATUR, the many grass plains, plants, flowers, bushes and trees improve the bio factor by 5 percent.
