A circle of like-minded people has formed around the space, who actively become members of the "Friends of the Square Club". Being a friend of the space is an honorable mission and a common global practice. During the creation of the space, local residents were actively involved in the development of the concept, brand, architectural plan, design of the square, learned to cooperate with local authorities, conducted independently and participated in various events.
Square 21 is made of eco-friendly materials. The request to create a public space in an eco-style was received from local residents of Dobropillia. This indicates a decrease in consumer attitudes to life.
The project was implemented by the NGO Misto-sad and the project "Ukraine Confidence Building Initiative" (UCBI II) with financial support from the United States Agency for International Development (USAID).
