Polyclinic Kostelní in Ostrava

Urban Planning Solution
The polyclinic building is situated in the location of the original development from the early 20th century on Kostelní Street. The site for the polyclinic is located in the center of Ostrava, adjacent to the pedestrian zone between Masaryk Square and the Miloš Sýkora Bridge. The block of houses where the polyclinic is situated is bounded by the streets 28. října, Kostelní, Havlíčkovo nábřeží, and Biskupská, which was created by breaking through the original development of city houses. The construction of the health center serves as an intermediate link between neighboring plots, where further construction is expected to complete the existing unfinished block of houses. The massing of the building adheres to the existing structure of the surrounding development.

Architectural Solution
This is a fundamental reconstruction of building no. 96 and the new construction at the site of the original neighboring building no. 98. The existing building no. 96 retains its street façade and entrance areas, as well as part of the load-bearing walls and foundation structures. Other constructions which did not meet the new operational and structural requirements are demolished and replaced with new structures.
In shaping the volume of the building, we drew from the mass of the street part of building no. 96 and the mass of the neighboring house. The polyclinic presents itself to the street as two adjoining objects - old x young. The original historicizing façade of building no. 96 is preserved and reconstructed. The façade of the new building is designed in contrast to the neighboring heavy, historicizing façade as a lightweight, semi-transparent, cubic mass not exceeding the cornice of building no. 96, with a set-back top floor at roof level.
Window openings extend the full height of the floor and their arrangement corresponds to the vertical division of the neighboring building, while they are contrasted by being irregularly placed in the horizontal, reflecting the internal operation of the building.
The front façade is divided into a ground floor part and the rest of the above-ground floors by placing the inscription POLIKLINIKA KOSTELNÍ in accordance with the division of the neighboring historicizing façade. The ground floor itself is clad with horizontal strips in a similar spirit to the neighboring house. The front façade is covered with white enameled glass cladding. The recessed mass of the top floor is clad with cembonit in a dark grey shade.
The building is unified towards the courtyard with facade plaster in white. The section between the window pillars of the courtyard façade is clad with cladding of dark grey enameled glass. This courtyard façade is interrupted at the last floor by a cantilever - lookout, which is surrounded by cembonit.

The functional content of the polyclinic is conceived as a private outpatient facility.
At the level of the first above-ground floor is the main entrance to the building including an entrance for disabled persons via an elevator, and there are also offices and a pharmacy placed here. On the 2nd to 5th above-ground floors, doctor's offices and preparation areas are located. The basement accommodates storage rooms and technological support for the building's operation. There are also changing rooms and washrooms for staff. The portion of the ground floor facing Biskupská Street creates a passage to the courtyard part of the property with access to a ramp to the underground garages of the neighboring administrative building on Biskupská.

Structural and Technical Solution
Structurally, the building is divided into two structural units. In building no. 96, the load-bearing system connects to the original structures, which are partially preserved in the basement, and in the above-ground floors, new load-bearing walls are positioned in their original position with regard to different static requirements. The load-bearing system of the building consists of a masonry three-wing structure, which consists in the part oriented towards the street of the existing load-bearing walls made of CP and new load-bearing walls made of ceramic blocks.
The new construction has its own load-bearing structure, which is separated from the original building. The load-bearing structure is a combination of load-bearing masonry outer walls made of ceramic blocks and a reinforced concrete skeleton.
The existing ceiling beam constructions of the building are replaced, in consideration of static requirements, with new ceilings combining I-beams coupled with a reinforced concrete monolithic ceiling slab. The horizontal structures of the new building consist of reinforced concrete monolithic ceiling slabs.
The external masonry is additionally insulated. The façades made of enameled glass and cembonit are ventilated, while the courtyard and side façades are treated with a contact insulation system with white plaster.
The building is partially roofed with a gabled roof with a wooden truss and partially with a flat roof. The covering is proposed to be made of ceramic roof tiles. Flat roofs are always designed as single-layer, with the surface consisting of gravel.
