Really like this style: Edwarian mono-pitch lean-to greenhouse, front cold frames. Would like to create a similiar look using salvaged brick and windows!--only thing I would like to add is the other half and another set of cold frames.
Build this trellis and raised garden box combination. Cucumber, snap peas, green beans, tomatoes… ah, just think about that fresh organic food you can grow in a small area! Another huge advantage is that harvesting is a breeze.
