General report on competition:


/ARCHITECTURAL CONCEPT/

The concept of the proposed solution has achieved several main goals: to improve the quality of location, extend green and pedestrian areas, solve traffic problems and provide cultural and educational functions. There are a few location problems easily solved in order to make the final product more attractive, easy to access and to raise architecture to its highest level. Historical elements, such are door arches on the Belgrade’s fortress, and the rhythm of the columns of Beton Hala, are one of the main pre-existing principles used in architectural concept. The door arches are both used as a functional element as well as to appeal to visitors of Belgrade, a potentially new European Culture Capital.
The concept has several main principles:
/to make the site connected to the fortress, Kalemegdan park, and city proper;
/to eliminate the influence of traffic and street noise with its physical barrier;
/to produce new architecture that draws upon the existing historical elements without overshadowing it in order to elevate the appeal of the location.
To achieve these goals, the site has been divided into four segments / units:
1. The terrace
2. Commercial building
3. Exhibition building
4. Traffic and parking area

The position of the terrace, all along the river coast and above Beton Hala, allows it to connect some of the main functions of the area, such as:
/pedestrian focal points
/easy access to any point of interest inside and around the location
Walking along the terrace invites users into both the exhibitional and commercial premises. At the same time, the terrace offers a great view of the river on one side and of the fortress and Kalemegdan park on the other. Solving the traffic problem by moving it to the underground levels helps provide the visitors with a calming and relaxing atmosphere along the terrace’s riverside.
The terrace has a wooden covering to enhance and simulate the natural surroundings for the visitor, and to blend in well with Kalemegdan park, which itself is slowly transforming into a terrace by the river.

The commercial building leans on the terrace and spreads south of the exhibition building. The shape references the existing architecture of Beton Hala with its own dynamic column rhythm that invites visitors inside. Laminated wooden girders match the wooden covering of the terrace. The rhythm of the arches follows the rhythm of the existing Beton Hala columns bellow. This shape of the building imitates the shape of hangars on the river dock connecting the architecture to the coast.
The commercial building is divided into 3 units, each with several premises of its own. Space between these units allows easy access for pedestrians to other points of interest on or around the site. The big and open space of each of these premises can be used for various purposes: restaurants, cafe bars, shops... Some of the high-ceilinged premises may even serve as galleries. The advantage of using big open spaces with the glass façade allow for an easy change of function: from cultural to educational, and commercial alike. The third unit of commercial premises located on the southern part of the site can be used for various types of shops, but also for any other function.

Glass façade invites visitors inside. Form inside, it provides open view to the river and to the fortress on the other side. Viewers from the river are attracted by dynamic glass facade and big open spaces. On the other hand, the same facade orientated to the fortress attracts viewers from this direction.
Commercial building, like other on the site, are easy accessible from any point and it has direct connection to the terrace, fortress, underground parking levels.. Any visitor coming by car or public transport - the tram, easily access to commercial building.

Exhibition building is set up on the northern part of the site. Since it has cultural and educational purpose, exhibition building demands position away from city streets with traffic noise. This kind of attractive location asks for attractive and monumental architecture. At the same time both function and remarkable shape are applied. Open space with unusual big and small “balls” inside and outside attracts visitors to investigate the space.
Exhibition building is contained of main and temporary exhibition areas with all auxiliary premises inside. Both conference hall and two main staricases leading to the upper floors do not cut the view towards the fortress, and oposite. Conference hall and staisrcases are following the angle of hill towards the Kalemegdan park. The result is very simple, the view is not broken by the building, the view remains towards the fortress, and from the fortress: the terrace can be seen through the building. The main staircase allows views in both directions, but at the same time it is great open space for visitors who can use it as wide and long space for relaxing.
The first floor has great advantage of having open space exhibitions area. It allows some exhibitons to maintain on the open space but inside the building at the same time.
Façade is designed as very contemporary, but with elements from native serbian culture and folklore. Façade is system of ventilated façade and will affect to energy efficiency which is very important for sustainabilty.

Pedestrian communications are very important for the site. This solution offers the maximum quality for any pedestrian coming from any direction and allows easy access to any point. Since the traffic is solved in underground levels, the whole site is left for pedestrians. Site with no traffic and no noise gives to the visitors chance to run away from everyday crowd and stress just inside the city central area.

Connection to the fortress is solved with ramps all the way from the fortress to the site. Ramps on each side has small plateau that provides space to make a rest, but also to provide a view to the river and new sensitive architecture. Ramps on different sides and on the different levels allows viewer to see and feel buildings and whole site form various angles and heights.
These different views invites visitors during their walk all the way down from fortress to the site. Traffic is moved into underground level, physical barrier and noise are eliminated and there are no elements that ruin the feeling of new architecture.

Connection with existing Beton Hala is provided in 4 main points. These points of connection has platforms, elevators and stairs offering vertical communication both for bycicles and pedestrains to the terrace and pedestrian plateau from river side walkway. Platforms with its size offer better view to the river and to the new premises designed on the site. The southern vertical communication also has great advantege to connect the site to the “grand steps” over Karadjordjeva street and which gives connection to the city.

Idea for the traffic and parking area is to make pedestrians as primary users of the space. The heavy traffic passing through location is the biggest problem in connecting the site with fortress and further to the city. City of Belgrade has main pedestrian connection following: Center – Kneza Mihaila – Kalemegdan – Beton Hala. This connection is broken at the point of Kalemegdan – Beton Hala by heavy traffic. Physical barrier and noise are solved by putting the traffic underground. In this case we have clear pedestrian connection to the forteress and to the city.

Main traffic problems are solved with two tunnels:
/ Tunnel in Vojvode Bojovica Boulevard
/ River side tunnel (next to the railway tunnel)
Both tunnels, which are one way direction tunnels, are very important for resolving barrier and noise problems on the site in the meaning of traffic. This solution gives several very important improvements for raising the quality of the site:
/physical barrier is resolved
/problem of noise is resolved
/pedestrians get the maximum quality of using space
/tram lines are on the level for pedestrians and do not intersec with road traffic at all
/both existing traffic lights in Karadjordjeva street are removed which will make heavy traffic much faster and easier in this area that is very important for the city

All these improvements achieved the main goals: the solution for traffic problem, providing pedestrian connection of fortress with the site and extending the green area for pedestrians and bycicles. Although Belgrade has not many parks in old part of the city, this extension of green and pedestrian area is very significant for both inhabitants and visitors.

Parking can also be a problem in terms of creating noise and a physical barrier to the structure. For this reason, car and bus parking is designated to the underground levels. Removing both traffic and parking from the street level and areas intended for pedestrians offers maximum access to the site.
Parking for 833 cars and 15 buses is designed in 3 different levels:
/level -3.50m bellow ground
/level -6.50m bellow ground
/level -9.50m bellow ground
Two entrances exist on levels -6.50m and -9.50m as well as three different exits, (each level has one exit) which are leading to Vojvode Bojovica Boulevard tunnel and to Pariska street. High number of entrances and exits offer ease of access to the site.
Underground levels solve other problems such are: bus parking, loading/unloading of passsangers and/or cargo, storage, technical rooms, area for waste, etc.

Self-service gas station is designed on the northern part of the site. Advantige of new position is that gas station is accessible from both directions in Vojvode Bojovica Boulevard, towards north and towards south direction.

Sustainabilty is one of the main goals of this project. The complex on the site with all premises will have climate certificate by applying several systems. The sustainabilty is achieved with these systems:
/system of collecting the water from the roof – storing the water in tank – using the same water as technological water
/using materials that affect to energy efficacy. The façade system is with environmentally-friendly materials. This system with proper isolation and with double layer glass does not allow loss of energy, and at the same time does not allow climate effects from outside to the building
/roof of exhibiton building is covered with photovoltaic thin-film that collect sun energy. Sun energy is used for heating and/or cooling water inside system. Result is using the renewable energy. On the other, commercial building, the roof is covered with recycable material.
/heat pump uses water from the Sava river. System with heat pump makes energy efficacy the heating and/or cooling system
All these systems that are used will raise this project to the highest level in climate certification, such as “ClimaHouse” certificate.
