The family house in Maksimir arises from the idea of a whole that fractally breaks down into smaller segments. The unrefined initial volume is subtracted until the desired form reduced to the essential is achieved. The design of the house starts from a simple geometric body – half a cube. Positioned and rooted in its habitus, it begins to modify. Half of Plato’s cube is cut by two axes dividing the floor plan square into four equal quadrants. With two additional axes moved out of the centre, a central “cross” is created. With the establishment of a set of basic rules, the building begins to generate itself. All service areas are located in the central cross. The remaining interior spaces become living and sleeping rooms, and the exterior spaces enclosed intimate courtyards. This achieves a clear interrelationship and interdependence of individual parts of the house. The circular balcony with a filigree metal fence invites us to the final step in exploring the house. The moment of maximum spatial introversion is once again interfered with the moment of greatest extroversion. This emphasized repetition of the same scenario serves to better understand the construct.
