Waltrovka Kindergarten

DESCRIPTION OF THE BUILDING
The plot for the kindergarten, garden, and parking was defined by the existing pedestrian paths between the residential buildings in the Waltrovka complex. The proposed kindergarten is located at the northern edge of the construction site, allowing the remaining part of the land to be optimally used for a garden in the southeastern part and for quiet transport and parking in the northwestern part.
The kindergarten is designed as a two-story building with 4 classrooms for 4x18 children, totaling 72 children, with play areas and outdoor terraces oriented towards the southeast. The building has one main shared entrance, a foyer, and an entrance hall with a staircase, providing access to all 4 children's activity rooms (always through a dressing room) with their own facilities. Each classroom can thus operate independently of the others. Children's meals within the kindergarten are provided from delivered pre-prepared dishes. For this purpose, a kitchen prep area is designated on the ground floor, shared by all sections of the kindergarten, with serving to individual classrooms and to the upper floor via 2 dining elevators with direct serving to the activity rooms.
The mass of the building follows the rounded shape of the plot and the pedestrian path to the north, symmetrically tapering at the sides. The kindergarten building thus vaguely resembles the silhouette of bird wings or an airplane, responding to the original industrial use of the Waltrovka site where the kindergarten is located. The exterior façade consists of a vertical wooden cladding made of treated pine wood on the north and northeast sides, securely treated using the Thermowood method. The wooden profiles are anchored to the underlying grid with a ventilated gap and mineral thermal insulation, protected by a black diffusely open membrane. The part of the façade facing the kindergarten garden features a standard contact insulation system made of expanded polystyrene with a colored silicone plaster in light gray. Large-format French windows in the southern façade allow direct access to the external terraces of both playrooms on the ground floor, as well as to the garden and children's playground. In the case of the upper floor, direct access from the playrooms to the balcony is also possible, as well as to the garden and playground via an outdoor steel staircase.

RELATIONSHIP TO TRANSPORT SERVICES AND TECHNICAL INFRASTRUCTURE
On the western side, a parking lot is created with space for deliveries, with direct connection to the main entrance of the building. The construction is connected to the sewage and rainwater drainage, water supply, gas supply, and electric network in the eastern part of the plot.

LOCATION OF THE BUILDING, RELATIONSHIP TO PUBLIC SPACE
The building is located on a narrow plot between residential buildings, along a communication link between the western and eastern parts of the complex, connecting to a park area on the east. The pathways alongside the building ensure passage further west into the original development of Jinonice.

STRUCTURAL AND CONSTRUCTION SOLUTION
The building is designed as a reinforced concrete monolithic frame with two above-ground floors, reinforced concrete monolithic exterior walls and ceilings, and non-load-bearing interior partitions made of hollow ceramic blocks. The structure is founded on a reinforced concrete slab supported by strips under load-bearing walls and columns. The entire foundation structure is supported by piles due to the inadequate load-bearing capacity of the substrate, composed of historical backfill.
