Commercial and administrative center Vinice – the new headquarters of TV Prima
Like every human being, every house has its own life story. As architects and civil engineers, we were present when the Vinice commercial and administrative center with the adjoining Palouk residential complex was established almost twenty years ago. After the long-term majority user moved out after almost two decades, and after the new owner decided on a complete reconstruction, a new period of life for this building begins. We are glad that we were able to participate in the reconstruction, which transforms the original building into a modern commercial and administrative center. The aim was to create a pleasant working environment surrounded by greenery, which is also located near the city center. When designing the overall modifications in terms of technological solutions, attention was paid to the impact on the environment and the amount of energy needed for the operation of the building
The functional use of the building is mostly administrative with additional services on the ground floor of the building – supermarket, pizzeria and cafe. The basement has three underground floors which serve as technical facilities, storage facilities and underground garages. The first four floors are the new headquarters of Prima TV and radio. Television studios were built into the space of the original hall of the building. The other above ground floors will be used as rentable office space. These realized areas are prepared for the tenant’s client installations. Office spaces are designed to allow flexible layout according to the needs of individual tenants. Thanks to the internal atriums in the floor plan of the building, it is possible to efficiently distribute workplaces with regard to providing daylight. The quality of the working environment is also enhanced by the newly designed atriums with greenery. Another revival of the interior is the new representative entrance hall and elevator lobby on each floor. An important part of the reconstruction is the new appearance of the external appearance of the building. Furthermore, the public space and the ground floor in the immediate vicinity of the building, including greenery, were also revitalized.
The multifunctional building has 8 above-ground and 3 underground floors with a floor plan of 81×76 m. The upper floors are two blocks, north and south, which are connected by connecting necks. The load-bearing structure of the building consists of a reinforced concrete monolithic skeleton supplemented by reinforced concrete monolithic cores. Columns have a basic dimension of 400×400 mm are in the transverse direction and have spacings of 4800, 6000, 6400, 7500 mm and in the longitudinal direction of 4600, 6000, 7100, 7500 mm. A new construction element is the installation of television studios into the original hall of the building. The roofing is designed as a two-level roof with visible three-dimensional trusses to a height corresponding to the construction height of the floors, on which the ceiling structures are suspended. The final layer of the roof cladding was the composition of a stonecrop green roof in combination with a local terrace made of wooden slats. Due to the fact that the reconstructed building was approved in 1999, it was also necessary to solve the complex reconstruction of the facades not only in terms of aesthetics, but also thermal technology. Thanks to the new thermal insulation of the building and the use of new aluminum frames for the openings, the energy efficiency of the building has been significantly improved. Additional insulation on most facades is covered by a system overhanging the facade made of alucobond in a combination of gold, white and black.
