The basic concept is to organize the urban park in three entities at two levels (+ 239,00 και +233,00).
The three entities are:

(a)    The already constructed west area which remains as it is with the addition of the new fence, surrounding the park as a whole
(b)    The central linear area north of the existing athletic fields to the boulevard. This entity houses the main park including the basic supplementary facilities (restaurant, educational, administration etc.) with an artificial lake- river system as the main organizational element of the park.
(c)     The almost rectangular eastern unity, where the artificial river ends to a freely shaped lake, and which houses the zoological garden and the building facilities which support it.

The two basic levels are:

(a)    The level +239,00  –that is the level of surrounding streets– where the main part of pedestrian movement is located and which coincides with the terraces of the buildings underneath.
(b)    The level +233,00 where the entrances of the buildings and the surrounding open spaces and arcades are located, in close relation to the artificial lake-river system (level +232,60)

 The basic design principles are the following:

(a)    No building is raised higher of the level +239,00 except the glass pyramid of the restaurant, the orthogonal small kiosks covered with plants, and part of the bird and monkey cages, so that the visitor is able to see predominantly the trees and plants and to “discover” the relatively lowered buildings and the open spaces surrounding them. These open spaces and buildings, with their strict geometry, reproduce the deeper characteristics of classical organization, especially in the central square facing the restaurant and in the open air theatre area, including the thematic parks.
(b)    As far as their spatial layout is concerned, the park and the zoo are separated and, at the same time, connected through a check point passage under the bridge so that their function is allowed independently from each other, if the park owner whishes to do so.
(c)     The pedestrian movement is hierarchically organized in three categories:

a.       The main pedestrian streets which follow the general geometrical 45 degrees grid of the park and are covered with gravel concrete. Some of the main pedestrian streets are also used for emergency traffic, as shown in the respective drawing, which summarizes the movement scheme of the proposed park and zoo
b.       The secondary streets, following free geometry and covered with concrete cube stones, and
c.       The pathways covered with stabilized soil

(d)    The park is crossed by an artificial lake-river system, with a maximum depth of 3,00 m.  The system starts from the west lake and the marina, goes parallel to the main pedestrian street, forms a second lake in the central square (which marks the end of boat movement), enters the zoo area and ends in the lake in the centre of the deer area. The water is in a state of continuous flow from east to west supported by drills and recycling.
(e)    The main entrance is located close to the junction between the main entities of the park and is orientated so that the entering visitor understands clearly the basic movements and the distribution of the main facilities of the park. The organization of the main entrance and of parking lot allows the late night opening of the restaurant when the park is eventually closed.
(f)      A whole system of artificial lighting is provided for the pedestrian streets, the trees, the lake-river system, the walls etc. The plant for electricity supply, together with all the other central electromechanical installations, is to be located in the underground part of the parking lot situated between the existing football playgrounds. The necessary generator can function with natural gas if in the near future a gasification branch for the settlements ‘Aerodrom’ and ‘Novo Lisice’ is provided.
(g)    The whole park is protected by a peripheral “green” fence consisting of a double two meters high grid including shrubs, creepers, and trees, planted in the one meter wide zone between the grids.

The function of the complex, during the transitional period of the construction of the vertical motorway and the bridge, is guaranteed by the use of the two entrances, one in the already constructed western part and the other in the eastern edge used permanently as service entrance of the zoo. Additionally the main entrance can also be used by slightly transforming the existing secondary road and parking of the athletic installations south of the park.
