Designing in the mountains gives a pinch of freedom that is hard to achieve within an urban environment. Thanks to the absence of strict, spatial and regulatory restrictions, the project for a single-family house called House N1, has been conceived and developed in such a way as to maximally "escape" from the typical mountain architecture and offer both spaciousness and comfort to its future owners. The house is developed on two levels, contrary in appearance and function. The first level is completely underground, and the only element that marks the presence of such is the entrance to the garage. This part of the construction houses both a two-car garage and utility rooms. It also houses a roomy bedroom with an en-suite bathroom, in front of which an English courtyard was designed to eliminate the possible unpleasant feeling caused by the lack of other windows in the room. Thus, the bedroom remains bright and at the same time ultimately isolated from the outside environment, which gives it extra coziness. The second level of the house is located at elevation 0 and represents the actual, habitable part of it. It houses a spacious living room with dining area and three bedrooms, each with an en-suite bathroom. All rooms are open to the exterior, thanks to the glass facade that goes around the entire floor and that ultimately "brings" nature inside, so that its presence is felt at every moment. The supporting structure of the house is completely shifted to the central part of the building, where all service areas such as bathrooms, kitchen and laundry premises are located. The design of the building is marked by irregular shapes, and a main role for this is played by the pitched roof of black, burnt wood. The inclined planes in which it is developed "open" more or less the interior space to the exterior, depending on its functions. The highest part of the roof is at the main entrance, and the bedrooms and the relaxation area in the living room are maximally covered by it, so that they are more isolated and cozy. The main bedroom also has a fairly high ceiling, but the direct visual contact to it is reduced viewing from the lower level at the entrance to the garage. A special place is dedicated to one of the existing trees on the grounds, which, instead of being cut down and removed, "cuts through" the roof and thus brings the forest landscape closer to the interior space. In order to achieve a specific, mountainous look of the house, all interior coverings, such as the floor, wall coverings and ceiling, are covered in wood, which creates the illusion that it was made entirely of wood. In addition to the roof part, irregular shapes mark the house itself, in plan direction. In order to achieve dynamism and a modern, somewhat futuristic look of this mountain retreat, slanted lines play an important role in its design. From the point of view of the distribution of the ground floor, leading for this purpose is the central load-bearing wall, located diagonally on the ground, which guides the direction of the facade of the bedrooms and forms different open and closed angles, atypical of classical construction. In this way, additional space opens up in the living room, which makes it even more spacious and free and brings added value to the overall feeling of a modern home. The atypical shape of the two adjacent bedrooms is not at the expense of their ergonomic distribution either, as corners formed in this way add more free space in the rooms, and the arrangement of the wardrobes and beds is taken care of by the long straight walls, which do not require specific or impractical furniture. In the main bedroom, parallel lines form the wardrobe and the position of the bed, and the bathroom is divided into two parts that are housed in the irregularly shaped areas, namely the inner part of the house and its periphery. The low-rise construction and the natural materials used in it allow minimal intervention in the change of the environment around the building. By repeating the whimsical shapes of the mountain peaks in an architectural plan, the house harmonizes with the environment and at the same time asserts its modern and innovative character.
