The project is located at the Naschmarkt (Vienna), the market has two main conditions. Most of the time it is used as a parking. Once a week there is a flee marked. So it is either very crowed or completely empty. The greenroom is visible form fare away and brings a contrast to the concrete place. It provides an exclusive experience, when you enter the green room on the top of a building. And also the project it self has two conditions, it changes from summer to winter. In the room you have the experience of a complete surrounding of nature as well as the opening and framing of the sky. So enjoy the freedom of the sky, when it is to crowded or find your self in the middle of the nature if outside is only concrete.
