The basic elements of our design - the solid brick cladding and the distinctive silhouette that visually lowers the height of the houses - are based on the belief that in addition to the diversity of the environment, its integrity should also be strengthened. By designing the upper floors of three similar yet distinct apartment buildings in terms of materials and tower-like form, we aim to achieve the self-evident and unobtrusive individuality of traditional urban and rural development, which at the time was manifested by commonly shared values, technical possibilities and a reasonable degree of need to express the buildings' own identity.
We propose to allow for the individuality of individual houses, but within a framework of chosen regulative principles that would avoid the excessive heterogeneity of the development. We intend to unify the integrity and coherence of the environment through the material or similar characteristic volumetric design of the houses, supporting the identity and individuality of the houses not only through the facades but also through the material design itself.
We applied the general conceptual thesis of our competition design for all three blocks to the scale of the three proposed houses, which differ subtly, apart from the colour of the bricks, also in the width and frequency of the tower-like elements, naturally reflecting the different conditions and possibilities of the development of the individual plots. In our case, requiring the application of all three basic principles of designing staircase apartment buildings. Either on a narrow plot with a relatively small section width and a space-saving staircase solution directly illuminated from the courtyard façade (02), or on the contrary on a plot with a large staircase section width (09) or with a corner position of the house (04), where the staircase space is more comfortable and illuminated not only by the façade but also by skylights over the internal courtyards. The use of tower-like elements helps to reduce the scale of the development, visually lowering the height of the houses and thus recalling the pleasing proportions of the height of the historic buildings of Smíchov.
The house is situated on a plot with a sharp angle at the intersection of Šiklová and Nádražní streets. The corner on the opposite side is built up with two traditional houses with a bevelled corner.
The house has 6 floors. On the ground floor there is a commercial area divisible into four parts on two levels. There are 5 flats on a typical floor, the flats at the gables have bedrooms also facing the courtyard. On the top floor, both gable apartments have rooftop gazebos, allowing panoramic views of the city as well as use of the residential terrace on the green roof of the building. There are a total of 25 apartments in the house, ranging in size from 2+KK to 5+KK. In the two basements, there is car parking and basement cubicles for all apartments in the house, plus additional cubicles for the neighboring houses. The technical facilities of the house, including a boiler room common to the neighbouring houses, are in the first basement.
The main entrance to the house is along the gable from Šiklová Street. The staircase with the elevator is located at the courtyard facade, from the staircase landing there is an entrance to the semi-public garden in the courtyard.
The structural system, in line with the design of the whole block, is a wall system made of monolithic reinforced concrete, supplemented by columns in the lower building and on the ground floor. The floors above ground are separated from the lower structure by vibration springs. The ceiling slab of the first basement transfers the loads of the above-ground floors to the basement walls and columns, the position of which is clearly determined by the operation of the garage, by means of massive spans. The elevator shaft and stair arms are acoustically separated from the rest of the building. The partitions and partly the partitioning structures are designed in sand-lime masonry. Loggias and balconies are designed with ISO beams, terraces above the living space on the 2nd and 6th floors and on the roof are designed as pitched roof structures.
The perimeter walls of the house are contact insulated, the façade facing Nádražní Street is lined with brick strips of dark brown shade in combination with grey plaster in the receding parts of the upper floors. The façade of the courtyard will be provided with a trowel plaster of ochre shade and complemented with grey plaster on the staircase cornices. In the ground floor, aluminium doors and shop windows will be fitted with metallic anthracite paintwork, the windows of the flats will be dark painted wood. The external railings will be glass to Station Street and metallic locks in anthracite shade to the courtyard.
