The topic of this final thesis pertains to the architectural design of a detached family house in Osijek, located on the left bank of the Drava River, where the renewal and revitalization of the Tvrđavica settlement are planned. The settlement is primarily intended for residential purposes, featuring a prevailing typology of detached family houses. In accordance with the Urban Development Plan of the City of Osijek (PPUGO) and the project requirements, a conceptual and partial execution design has been developed. The plot is undeveloped and situated within a neighborhood of family homes of varying typologies. The regulatory line of the plot extends along the northern side, adjacent to an existing street running in an east-west direction. Vehicular and pedestrian access to the plot is from the north. The plot on which the new family house is designed has a regular trapezoidal shape, with approximate dimensions of 22.00 x 38.00 (44.00) m, covering an area of 902 m². The family house is designed as a detached structure, consisting of a basement, ground floor, and first floor. It is intended for a large family, consisting of a father who works in a factory, a mother employed in administration, and two school-aged children. According to the project, the built-up area of the plot is 220 m². The total net area of the family house is 480.30 m², and the gross area is 624.39 m². The building is constructed from common materials used in construction for both structural and finishing works. The load-bearing structure consists of brick blocks and a system of reinforced concrete columns and beams. The external walls are 25 cm thick, while the internal walls are 12 cm thick. The roof is designed as a flat, non-walkable roof. The exterior windows and doors are made of aluminum profiles with triple glazing, providing both thermal protection and a comfortable, secure use of the building. The interior joinery is made of wood to create a warmer atmosphere. The floors are designed as floating floors with thermal and sound insulation. The final floor finishes depend on the specific room and its intended use. The house is connected to the public water supply and sewage system, as well as to the electrical and gas networks located within the public road corridor. According to the project, all necessary installations, pipes, devices, and equipment are planned and installed to ensure the building is self-sustaining and environmentally efficient.
