This project was team work, in our group was 4 international students: Lucie Linderova (Czech), Radoslaw Stanko (Polish), Alba Fernandez Arias (Spanish), Tadas Semenas (Lithuanian). The goal was refurbish social housing development Mimersgade from 50´s. Buildings had a lot of problems with moisture, cracking, sound and thermal proofing. The purpose of this project is to provide a better living place for tenants. Therefore we suggested changes in both urban, architectural and interior scale with strong contribution to sustainable development and maintenance. The project focus is to create multi-functional natural areas and variety of rental structure. We suggest building an extension in order to make the public areas more cosy, provide common rooms, office, boutiques as well as increase the apartment number. We decided to use cross laminated wood for extension structural system and recycled steel to reinforce some parts of existing walls.
