The focus of this project is coexistence. Not only how we design buildings to coexist within our own human societies, but also how this concern may be extended to facilitate the existence/dwelling of other species. The topic is investigated through photography, drawings, models, and text. The result is a strategy for wetland restoration at the former airport in Karlstad that today is a drained grass field. I have chosen to design a building for the kayak association and visitor facilities. The wetland will reintroduce a habitat for local wildlife. The inquiry enters the discourse of how architecture can work as an intersection where the city meets a natural phenomenon. The phenomenon in this case is the river Klarälven, where it flows through Karlstad and meets the lake Vänern. The proposal deals with spaces as well as species. City and wilderness. Building, dwelling and living along a river means to be in constant negotiation with water. A river is plastic force that runs through the landscape, changing with the season and the climate. We have learned to tame our rivers and drain our wetlands with the help of machines and technological interventions, and many have slowly become domesticized and controlled by humans. Except for the mountain areas, 80% of the wetlands in Sweden are managed by hydrological systems. Damaged wetlands means a loss of habitat for many species, and display other reduced ecological functions like CO2 storage , rinsing water, flood prevention and biological production.1 Technical interventions such as timber industry and hydropower technology have greatly reduced the wild animal kingdom during the past 200 years. As a result of human exploitation of nature globally, the biomass distribution index in 2018 has left wildlife vastly outnumbered by humans and domestic animals.2 This project aims to adress this global issue with a local gesture in Karlstad, providing better living conditions for wild animals, even in close proximity with humans. 1 11.11.2020 http://sverigesmiljomal.se/miljomalen/myllrande-vatmarker/ 2 https://www.pnas.org/content/pnas/early/2018/05/15/1711842115.full.pdf
