House O4 was developed in response to a fundamental duality in domestic life: the desire for privacy, safety and intimacy, and the equally important need to remain connected to the surrounding city and landscape. The site lies near the centre of Osijek, at its western edge, positioned in relation to the city’s cultural and social amenities as well as to its defining natural feature, the River Drava. The design therefore seeks to combine the calm and self-sufficiency associated with rural living with the intensity and accessibility of an urban setting.
The house is organised as a sequence of spaces around a living natural centre formed by two existing walnut trees. Rather than treating the garden as residual space, the composition makes it an active part of everyday life and a link between the different parts of the home. The building is set back from the street, yet its façade is not conceived as a defensive visual barrier. Instead, it creates a carefully controlled threshold that protects domestic life while maintaining a relationship with the public realm.
The architectural form combines lower wings with a more expressive central volume, broad areas of glazing and warm material accents. Interior spaces open towards the garden, allowing daylight, vegetation and seasonal change to become part of the domestic atmosphere. The result is an introverted house that does not become isolated: protected yet visually open, urban yet closely connected to nature. Its architecture presents privacy not as enclosure, but as a framework within which family life, landscape and the life of the street can coexist.
