This design is about bringing the green back in to the city center. This because the city center hardly has any green, we just see blue, grey and brown and this needs to change. This also has many positive side effects and can be used in adding many activities which are a benefit for the locals.
Making a botanical garden or conservatory in the city center you always add a solution with positive benefits. You provide a place where people can come to rest, a place that people feel more at ease and relax a bit. Also you tackle the air pollution and you can reduce stress levels and other mental problems.
By creating an open space in the conservatory it provides the possibility to organize events. The idea is to create a space which stimulate the human well being and to provide a place where people can go to during winter when there is hardly any green around in the city.
