Soil conversion, Prague-Vinohrady

House and Project
The apartment is located in the attic extension of a corner building in a relatively quiet part of Vinohrady. The building underwent a complete but poor reconstruction in the 1980s.
The original project divided the floor plan into two parts along the ridge of the roof, one part with a sloped ceiling and a possible height up to the ridge, and the other (under the roof terrace) with a flat ceiling that is relatively very low. In the middle of the floor plan, a load-bearing wall passed through as an extension of the so-called "chimney wall" in the lower floors.
The investors decided to hire an architect essentially only when the construction was already underway, and therefore the structural solution, external volume, distribution, and shape of the windows or height dimensions could no longer be significantly influenced. Very early on, however, we decided that the planned layout did not meet the requirements, and it was therefore significantly modified.

Concept
The basic decision was to divide the load-bearing central wall into variously wide pillars and highlight them with a surface treatment of cement plaster. The same cement plaster is also on the walls of the large bathroom by the bedroom and on the other side on the body of the fireplace in the living room. This created a characteristic element that runs throughout the apartment and unifies the individual spaces. Further division is created only by inserted veneered boxes and furniture partitions. The box for the small bathroom and technical room is set back compared to the series of pillars, thus creating a space for changing by the entrance and also allowing the low corridor in this part to open upwards.

Layout
The apartment is designed for a specific young family, so as to best meet their needs. In addition to the main living space with a kitchenette and dining table, it has two bedrooms, two bathrooms, a dressing room, a technical room, and a roof terrace above the lower part of the apartment.

Materials
The outer walls and ceilings are white, either with plaster or drywall. The central columns, bathroom, and fireplace are covered with cement plaster. Niches in the fireplace body and in the bathroom are lined with lacquered glass. The floor throughout the apartment is made of solid planks of American walnut, except for the bedroom with the bathroom, where due to durability in a humid environment, it is made of solid teak with inserted rubber strips. The furniture partitions and inter-room doors are covered with veener from Canadian maple. Standalone pieces of furniture - shelves, bookcases - are in white glossy lacquer.
The kitchen unit has doors and other visible parts lacquered in black, high gloss, with a countertop made of jointed rosewood.
The atypical furniture and the bathtub lining in the large bathroom are made from white Parapan.
The glass partitions and doors are primarily in Satinato finish, with clear glass at the top.
