It is a small park, founded in the idea of the trend of blue-green infrastructure. The garden is implementing before the construction of apartment buildings (currently underway), for which it will form an infiltration and retention area of rainwater. For this purpose, a small water area was designed, which is dimensioned so that even in very light summer precipitation it does not dry out and it is enough to "flush" from the roof capacity. It is a reinforced concrete tub with a high backfill of quarry stone (approx. 1.5 m) to keep the water cool and thus clean, as well as to maintain the effect of the water level and for safety when entering. Water from the water reservoir overflows into the surrounding areas, which have different types of surfaces, from brushed paving to gravel and grass polder, equipped with gravel seepage.
The park is set for a gradual successive development. At the beginning, it is more a work of striking design, which is the intention to suppress the feeling of emptiness at the foundation. Later, as vegetation is designed, the natural process will prevail. Stone rubble fields become willow and maple, gravel areas succulent communities, meadow modeling. The striking architecture will turn gray and age and merge with the vegetation, which will be gradually shaped by the type of surfaces and objects.

The central building of the garden is a reinforced concrete swimming pool, which is connected to the rainwater drainage system from the roofs and adjacent paved areas of the adjacent housing construction. The pool is flushed with rainwater, which overflows over the bridge into the adjacent polder. The two-meter-deep pool is stratified with a quarry stone from a large fraction to a finer one, one and a half meters thick. Half a meter is the water level. This experimental technology will provide a cool, unexposed mass of water, which cools the residue on the surface and should not lead to greening of the water, which is otherwise technologically very expensive. It is also about the safety of the water element. The depth of the water ensures its low temperature, but the amount of stone significantly reduces the need for water. The pool is therefore sufficiently flushed with every small summer rain and the level of 50 cm is again sufficient to keep it up to 3 weeks without rain.
The vegetation is established in contrast to the distinctive architectural appearance of the garden as a basis for successive development. The diversity of bulk materials will support the diversity of more natural communities. The architecture will gradually disappear in the vegetation.
