The Norrbotnia Line Dance project focuses on the expansion and densification of Piteå, a small city in northern Sweden. To accommodate the expected population growth, the thesis explores interventions to urban sprawl by reorganizing existing buildings along Kyrkbrogatan, a main street in the city. The interventions proposed are: "Repurposing," which integrates a train station within a supermarket; "Addition," involving a shift and addition of a public building to enhance its urban presence; and "Relocation," relocating a villa to a new site and utilizing its space for apartment buildings. Through the exploration of architectural expressions and the integration of dualities, the interventions propose innovative solutions that contribute to the city's future growth and development while preserving its unique identity. By seeing buildings as free of its site the project aims to counter urban sprawl and promote a sustainable urban fabric. Drawing inspiration from Piteå's history, including its Roman-influenced city plan and previous relocations of buildings. From residential, the relocation, my thesis Norrbotnia Line Dance moves along Kyrkbrogatan through Public Offices, shifting and adding towards the beginning and end of the city at the Train Station, with its repurposing, while facing the issues of continuity as we go down the line.
