We have had a greenhouse in our backyard since the summer of 2015 (almost a decade ago). The greenhouse lasted much longer than we thought, given that it is just a thin aluminum structure with transparent plastic wall and roof sidings.
We are planning a sunroom extension and had to remove the greenhouse. This past Saturday, October 19, was the day marked for disassembly. A friend of mine agreed to disassemble the greenhouse and will later attempt to erect and reuse it on his property.
