The building shows how we imagine people living in the future. The rooftop garden increases the biodiversity of cities, enhances the air quality and cools down the building through shading and water vaporization. Furthermore, the residents can use the garden to grow vegetables and fruits while farming the beds together. The ideas of sharing and community are the cornerstones of this project. The image of the building is based on the historic appearance, which was demolished during the bombing of World War II. Unfinished, raw and open, the architectural volume is a representation of its own remains. Materials: This project is the experiment of using unconventional materials in order to create high quality architecture in an urban setting. The construction methods are borrowed from industrial structures. Cost efficient and highly prefabricated materials guarantee a timely construction progress and economical implementation. Urban gardening: Every resident of the city house has access to planters for growing wholesome and healthy foods. The house becomes a symbiosis of organic structure and inner city housing. The presence of the plants increases biodiversity while also playing a vital role in shading and cooling the building during the summer. This building is a prototype for a future form of cohabitation that ensures access to healthy food and conscious community-based living in cities. Future Oriented Housing: The steel structure ensures a flexible use of space, which can easily be adapted for other uses. The plants on the roof are being watered with collected rain water and they are significantly reducing the carbon footprint of the building, by contributing to the cooling of the building through vaporization and shading.
