My greenhouse was once an ordinary one, until the climatic conditions of the earth changed and soon it offered a new home to other plants and animals. It has been there for a long time and gone through a lot of change, but never lost it's original purpose. Small fish now hide in it and new kinds of plants grow in the pots and on the surfaces.
