N HOUSE is a holiday house on the outskirts of Belgrade, on the slopes of Mountain Kosmaj. The object, as well as the exterior decoration, follow the configuration of the terrain with their design structure. The house is positioned on the upper part of the plot, which gives the fantastic view of surroundings from the glazed living room and spacious porch. Architectural shaping follows the traditional form of a hip roof in the interpretation of modern design through the treatment of the facade and the choice of materials. The dominant colors in the exterior are white and anthracite gray. Besides styrofoam, materials such as clinker brick and natural stone with wooden details are used for facade in order to enhance the aesthetics of the house. In functional terms, the architect responded to the client’s requests through a modern approach to designing a weekend home. The house has a spacious “open space” living area separated from the night zone with a massive wall with a fireplace. The night zone consists of two bedrooms and a bathroom. Large glazed areas towards the porch, as well as high and narrow windows, give the house a modern character, and at the same time connect it with the natural environment in which it is located.
