The area of Kollár Square is defined for the function of parks, landscaping and forest parks. The adjoining area enclosing the square is defined for the function of mixed territory - housing and amenities, civic amenities (location of the STU Park, Park One, Design Museum Space) of city-wide significance and overseas significance.The area of the square is separated from the built-up communication system. The square is unlocked from the neighboring buildings by the street system, it is not connected to the civic amenities in the built-up area except the One Park building.By urban design I am solving the public space of the Kollar Square located in the city center of Bratislava.The aim of the present proposal is to cultivate the public space of the square, to cultivate it, nowadays chaotic and opaque greenery does not create a safe space mainly at night, and create places for rest and space for sport.
