Residence Záběhlice

URBAN AND ARCHITECTURAL SOLUTION
The Záběhlice Residence is located in Prague 10 - Záběhlice. The area being addressed is part of the existing extensive sports complex and was previously used as a training soccer field. The northern boundary is formed by a blind arm of the Botič Stream surrounded by mature trees. To the east, the area is delineated by land used as a storage facility, and the southern boundary is formed by the AFK Záběhlice playground.
The urban solution was based on a fundamental compositional assumption, which was to supplement the spatial and functional composition of the Záběhlice sports complex. The horizontal mass of the single-storey building with an inserted function of accommodation, administration, fitness, and wellness is placed beneath a trio of trapezoidal two-storey buildings supported by columns. These two-storey masses, with their sloped façades and cornices, vaguely resemble a trio of boats drawn ashore, anchored in the treetops. They house above-standard apartments with roof terraces.
An integral part of the overall concept was also the creation of truly high-quality public space with plenty of new green and recreational areas. The ground floor of the building is complemented by new planting of mature trees, and the penetration of green areas from the northern boundary of the area, which is formed by the blind arm of the Botič, is also enabled. Extensive green roof vegetation is planted on the terraces of the building itself.
The transportation accessibility of the proposed design is solved by a new internal area communication connecting to the existing communication network. Parking is situated on the surface and in the underground level.
The proposed three-storey Záběhlice Residence can be mass-divided into two parts - a single-storey building with an inserted function of accommodation, administration, fitness, and wellness on the first above-ground floor, and a trio of two-storey buildings with above-standard apartments hovering above it.
The solid and compact mass of the horizontal single-storey building is opened on the southern side with a fully glazed façade. The remaining façades are conceived as visually closed, divided only by bands of French windows. Vertical panels of exposed concrete are used for the cladding. Parking is located in the underground level. Vertical connections between the individual floors are provided by a trio of stairwell cores with elevators. On the first above-ground floor of the building, there are fitness and wellness spaces, and accommodation units with spaces for administration. The entrance to the fitness and wellness area is from the western side, while the trio of entrances to the other facilities and the residential units is located on the north side.
Above the horizontal single-storey mass, a trio of two-storey buildings with trapezoidal floor plans and sloping façades float. Above-standard residential units are inserted into these "boats," which include large roof terraces. The solid and compact mass of the "boats" is articulated on the south side and one of the side façades with horizontal strip windows, which transition into arcades at several points. The short northern façades open generously with well-divided glazed walls towards the greenery lining the Botič basin. The cladding of the individual "boats" consists of horizontal metal panels 0.2 meters wide, with lengths ranging from 2 to 4 meters. The panels are made from copper sheet in three different shades. The shades were selected from the sample range of the Finnish company Luvata, which focuses on the production of semi-finished copper and its alloys. The selected trio of shades creates subtle transitions from light to darker copper. The copper panels are unevenly arranged on the façade, thereby enhancing the overall dynamic solution of the façade, whose surface evokes the bark of a tree. A significant advantage of copper is its considerable color range and non-permanence, whereby the gradually developing patina leads to variability in the color of the façade over time. This effect is documented in the image section of the presentation, as the photographic documentation was created over many months. The brilliant surface of the newly laid copper sheet did not remain shiny for long. Due to the weather, the color changed to chestnut brown. After many more years, a unique patina will form on the copper, which will protect it from corrosion.

TECHNICAL SOLUTION
The foundation structure consists of floating piles. The basement walls together with the floor slab create the so-called "white bathtub." The structures were designed as waterproof with limited crack width.
The load-bearing structure consists of a monolithic reinforced concrete skeleton with an irregular module, respecting the parking spaces in the first underground level. The skeleton transitions on the floor of the second above-ground level into a single tract with wall columns and parapets or full walls.
The external walls are reinforced concrete insulated with contact external mineral boards and clad with pre-patinated copper laminates (boats) or façade concrete panels (ground floor) - in both cases designed as a ventilated façade system with a typological system subconstruction.
All roofs are flat single-layered, sloping to internal drains. All roofs are designed as extensively greened or occupiable covered with wooden grilles.
