Doc intertwines the typology of a compact house- having a low environmental impact- with the specificity of a unique location: channel Borcea. The location and the desire of a new type of dwelling- a floating, multifunctional, mobile house- imposed special constructive conditions. The high water level variations of the river as well as budget conditioning have resulted in constructing a trailer like platform that can be relocated. The house is responding to site changes, changing with it. Mobility as its main feature dictated the simplicity of the space. Compact, with a simple, rectangular plan, the space gets a spectacular feel through the way it integrates in the location, complimenting it. Amazing images are brought in everyday use through wide windows and terraces. Although open, Doc provides visual intimacy from the city through its positioning. Its multifunctionality- temporary housing and meeting point for water sports lovers opens up exploration angles for a forgotten and undiscovered area- the Danube river around Calarasi. The building process took into consideration the context and the community by harnessing an existing and abandoned pontoon adapted to current needs.
