We has completed and handed over the documentation for the construction of the Semerínka residential project in Prague 5 Radlice. Construction of the project has commenced and its completion, including handover, is expected in 2026. Semerínka is being built on the land of a former industrial zone, which is now being transformed into a modern multifunctional area with a predominantly residential character.
The residential project Semerínka, realized by the developer Crestyl, will offer a total of 185 flats, 216 indoor parking spaces and 11 outdoor parking spaces on a built-up area of 4300 m² . The investment in the project amounts to CZK 1.5 billion. Semerínka, designed by architect David Chmelař of Chmelař architects, represents modern architecture that will harmoniously integrate into the surrounding environment. The building, which is composed of four blocks of different heights on a common base of entrances, garages and technical spaces, sensitively respects the terrain. The individual height-differentiated blocks will allow an unobstructed view of Prague and the rich surrounding greenery, while not overshadowing the surrounding buildings. The general contractor of the building is Metrostav a.s., Division 9.
The Semerínka Residential House emphasizes the safety and comfort of future residents. Libor Stránský of Obermeyer Helika, the project manager, explains, „As the main designer of the building, we designed a comprehensive solution to ensure the thermal and hygienic comfort of the residents in accordance with the client’s requirements. All apartments have been designed with heat recovery ventilation, modern underfloor heating and windows with acoustic parameters with respect to the surrounding buildings. In addition, most of the apartments are ready for the installation of external blinds, which will increase protection from external temperature influences. It goes without saying that the heat-exposed apartments on the upper floor will already be equipped with air conditioning as a basic equipment. In order to eliminate noise inside the building, the lift shafts are conceived as a „shaft within a shaft“ and all other areas, including the staircase landings, are designed with a view to reducing footfall noise.“
„As with every project, we follow the applicable regulations and standards, so the division of the building and underground garages into fire sections equipped with electric fire alarms is a matter of course. This will control the individual fire protection elements, including the fire shutters in the garages and the forced ventilation of the protected escape routes. In the garages, operational ventilation is designed to switch to emergency ventilation mode in case of higher CO concentration,“ explains Libor Stránský.
From the point of view of the structural engineering, which was also provided by Obermeyer Helika, the upper structure on the basement is carried out by framed wall beams. The structure features atypical trapezoidal windows and rounded corners, which require careful planning of the transfer of horizontal stresses in the reinforcement. Another important factor is that the entire project, including the technology, was created in 3D. This ensures better collaboration during both the design and construction phases in coordinating all contractors.
There is not much greenery on the former industrial site at the moment, so the project tries to bring it „closer to nature“. The proposed green area is 5340 m² . Green roofs with extensive or intensive greenery are planned on the lowered part of the building, and climbing plants will be used on the rope system in front of the facades. In addition, community gardens will be created in the interior blocks, whose irrigation will be solved by using rainwater retained in four newly built retention tanks.
