Multifunctional building Avion Ivanská cesta Bratislava
The floor plan of the proposed multi-functional building has the shape of the letter U. The main tract is based on the volume of the existing building of the Avion Hotel. Its extension and extension from the east and west sides creates a 91.55 x 18.5 m block, to which two extension tracts connect vertically in the end positions, optically closing the volume of the multi-functional house and thus creating a semi-private yard. The floor plan dimensions of the end tracts are 13 x 10 m. From the fourth to the sixth floor, the volume upwards gradually recedes in the direction of the neighboring Dornyk apartment building.

The main longitudinal part of the building reaches the height of five above-ground floors in its full volume, the sixth floor is set back. The ground floor of the building consists of a partially closed parterre with rentable non-residential spaces in the volume of the original mass of the building. The rest of the ground floor is occupied by covered exterior parking and an additional entrance to the newly built vertical core of the multi-functional apartment building. The main entrance to the building is left in the position of the original entrance to the hotel. It directly connects to the entrance hall and vertical communication.
The building uses a vertical support system designed as monolithic reinforced concrete columns. The horizontal support system is designed as cross-reinforced monolithic reinforced concrete slabs.
The facade has a contact insulation system with special insulation with a minimum coefficient of thermal conductivity and at the same time with a minimum thickness of insulation to maintain thermal comfort and maximize the usable area of the building.
Receding floors ensure compliance with the maximum possible index of floor areas. At the same time, they ensure compliance with the light-technical requirements of the neighboring apartment building on the southwest border of the plot. The receding floors created space for terraces of non-residential spaces on the 4th floor and also for apartments on the 5th floor.
As part of the event, modifications to the existing parking lot located on the plots of interest are being considered, where 141 parking spaces will be left from the original number of 157 parking spaces for motor vehicles and two parking spaces for buses.
1st floor (±0.000)
On the 1st floor, there is the main entrance to the building, in the original building, and a new entrance in the location of the extension. The entrances are solved in the form of entrance halls, from where there is access to the space of the staircase and the elevator, serving for residents and visitors of the multifunctional building, as access to the individual floors. In the laundry part of the building, in the place of the original house, there is a restaurant area with facilities and a partially covered terrace. The kitchen is supplied from the northeast side of the building, from the covered „porch“ area, where it is also planned to create smaller greenhouses for the needs of the restaurant. The entrance for employees is from the northwest side, through the original doorway. On the 1st floor there is also a gas boiler room with facilities, the location of which has been partially modified compared to the current state of the building, and a hairdresser’s area with facilities. Covered parking spaces are created under part of the extension, due to the fact that the extension of the building is without a built-up part of the ground floor. Close to the main entrances and in the area of the covered back „porch“, parking spaces for bicycles are also being considered.
2nd – 6th floor
The multi-functional house is designed as a layout of three tracts with a central corridor with two vertical communication cores, where the extension is based on the modular outline of the original building, with supplemented supporting module diagrams, which are evident from the drawing documentation. The building is expanded in plan in the extreme positions and forms the letter U, the side tracts of which narrow upwards. A uniform, compact shape is ensured by a secondary steel structure with built-in shading, where on two floors the shading covers the loggia of the administrative facilities and their terrace. Apartments and non-residential spaces located on the floors have steel structures to create balconies with secure rainwater collection and subsequent use for irrigation for climbing greenery, or roof terraces with extensive green roofs. On the 2nd floor and the 3rd floor there are 1 one-room flat, 8 two-room flats, 5 three-room flats and 1 apartment, on the 4th floor there are 3 one-room flats, 8 two-room flats and 5 three-bedroom flats, as well as spacious non-residential premises located in side wings of the building. Rational rectangular layouts maximize the usability and furnishing of individual apartments.
There are apartments on the fifth and sixth floors, while on the 5th floor there are 2 one-room apartments, 8 two-room apartments, 6 three-room apartments and one four-room apartment. The sixth stepped floor offers each of the apartments a more generous area and an exterior terrace with an extensive green roof. There is 1 one-room, 4 three-room apartments and 2 four-room apartments.
Roof
The roof of the multifunctional building is designed as a green walkable flat roof with a terrace, cafe and wellness area, including an extensive green roof. The premises are accessible to residents and visitors of the building itself, as well as to the wider public. The space of the wellness and cafe is formed by a protruding core above the level of the roof plane, where the living space itself is created for both establishments. The cores are optically connected by a steel structure that creates shading for the outdoor space of the cafe and wellness, with the possibility of outdoor screening (summer cinema) and the creation of smaller community gardens.
A closer specification of the division of residential units and non-residential spaces is evident from the drawing documentation.
