Restoring existing building and designing it into a new one is a great act of green architecture. This will prevent from entirely breaking those old buildings and eventually minimize the possible addition of landfills. The Vaeksthuset Botanical Garden by CEBRA is one great example of green architecture. Created fir a building competition, this building will have a series of round pods that are inspired by natural forms. It is also being covered with a pointed glass roof. The building also has facilities complex that will houses offices, cafes, and more greenery. Another space and the third of this building is an outdoor garden.
