You can have your own Lean-to Conservatory in your kitchen if it is roomy enough; all it takes to turn a kitchen into a kitchen conservatory is to install additional windows on the outside wall or feature a sliding glass doors that open from the kitchen onto a patio. In this case, turning the patio into a little room where you can relax in the warmth of the sun while you utilise its presence for propagating plants. Conservatories or orangeries as they are also known as were originally used exactly for the purpose of protecting plants.
