A lean-to greenhouse allows you to use a part of a wall of a house, a shed or a part of the terrace for the greenhouse when the greenhouse dream needs space to grow. At the same time, the wall of the house gets heated during the day and at night the heat is being released to the greenhouse. This helps to create good conditions for growth especially during the off seasons.
The optional steel base levels the greenhouse and provides a strong foundation. If you do not purchase the base you will need to build a brick base to construct the greenhouse.
