"Revitalizing a Vacant Skyscraper: A Case Study of the Ostrava High-Rise"
The Ostrava high-rise, built between 1965 and 1968 as part of the Jindriska housing estate, has been vacant for over eight years owing to technical and operational issues. Originally built as an apartment block, the 22-story building was later adapted as office space. Its façade contains asbestos and shows significant defects. The investment plan is to create an architectural and functional design for the reconstruction of the building, turning it into a combination of apartments and community space, which will consist of an observation café with views of the surrounding Beskydy landscape.
One of the main challenges of the project is the existing layout of the building, specifically the inadequate circulation core that does not meet current escape route and fire safety regulations. To bring it up to regulations, an additional communication core will be added on the north side as a separate structure, featuring an evacuation staircase, an evacuation lift, and a fire lift that will be controlled by the safety system. The elevators will also serve as service elevators for the residential units and the café.
The purpose of the study is to exploit the potential of the building's location in Ostrava in order to create attractive housing with exceptional views. Another challenge is the low ceiling heights on all floors, which will be addressed by designing windows and glazing to the full height of the floors, as well as horizontal and vertical fire partitions. Balconies with permanently maintained greenery will be added to improve the environmental quality and attractiveness of the building and to integrate it into the surrounding environment. The balconies and cornices feature an undulating design, and the use of façade blades on the full height of the building, that accentuate the horizontality of the building. The structural system of the building consists of a combination of concrete frame and the monolithic core around the stairwell, with bar elements for the spans and columns.
Sustainability will play a crucial role in the reconstruction of the Ostrava high-rise. The project will aim to reduce its carbon footprint and improve its energy efficiency. The building will be equipped with state-of-the-art HVAC systems, insulation, and high-performance windows to reduce its energy consumption and improve indoor air quality. The balconies and cornices will feature permanently maintained greenery to improve the building's environmental quality, provide insulation, and reduce the urban heat island effect. By incorporating these sustainability measures, the Ostrava high-rise will not only become a functional and attractive space for residents and visitors but also a model for sustainable urban development. The project will demonstrate how a building can be revitalized while also reducing its environmental impact and contributing to a more sustainable future.
The Ostrava high-rise presents an exciting opportunity to revitalize a vacant building and transform it into a functional and attractive space for residents and visitors. The project not only addresses the building's technical and operational issues but also aims to enhance its potential by integrating it into the existing surroundings and creating a community space with an observation café. The design also addresses the building's structural and safety concerns while proposing solutions to transform the overall aesthetic and livability of the space.
