* With technical description the summary recapitulation of surfaces will be shown.

When designing the apartments, the standards related to the minimum required room areas were respected, considering their purpose as well as the size of the apartment. All apartments have natural light and ventilation of the rooms (living room and bedroom directly, kitchen through dining room or directly), except for bathrooms and storage. Design provides the built-in dishwasher in the apartment's kitchen, which extends the length of the working surface in kitchen to the satisfactory size

The apartments for disabled persons haven't been considered within the building plot G.P.4, but will be included in the next phase of designing for the plots G.P.1, G.P. 2 i G.P.3.

Netto height in the basement is 260cm, at ground floor is 262, ie. 280 cm, and at first, standard floor is 262cm. Floor height at the ground floor is 340, and for the first, standard and roof floor is 290cm. The staircase area is naturally lit and ventilated.


The building is founded on reinforced concrete foundation slab and piles. Foundation slab lies on a bed of lean concrete, over which the hydroinsulation is done, surrounding the foundation slab and walls from all sides to the height of 30cm above the ground.

The structural system of the building consists of reinforced concrete skeleton system. The vertical elements- columns are placed at distances of 280, 540, 560 and 600cm. The inter-floor structure is reinforced concrete slab of thickness d=20cm. Staircase and elevator shaft are made of reinforced concrete.

The roof structure consists of reinforced concrete slab, the roof slope is 6%, and the roof covering is of PVC coated steel sheets on formwork boards with hydroinsulation.


External processing - Facade walls are made as a sandwich walls (brick blocks, thermal insulation, bricks) with plastering on both sides, and in some parts, the facade is made of the brick facade. For the external side of facade walls facade paint is used, and on the internal are smoothened and painted with dispersive paint. Concrete beams on the terraces were painted with facade color. Building skirting is finalized with washed- out concrete. Roof covering is made of PVC coated steel sheet. External doors and windows to the apartments are of PVC, and of aluminum are at the entrance, stairs and commercial offices, while metalwork items are used for railings on the staircases, terraces, cellars and technical rooms.
