The city is not homogeneous. In the central areas it is visually and functionally settled. But in the downtown areas and within the city limits? Everything there is often monotonous and gray, sometimes accompanied by environmental problems. This can be attempted to be solved by redesigning seemingly already completed objects. For example, a ventilation shaft.

Materials: costrocrete, glass
Location: peripheral areas of large cities

An environmental monitoring function is also available, by means of vertical green plantings in recesses in the outer walls of the concrete blocks.
