The greenhouse is built onto the western side of the house. This view is looking north.
Under the curved panels is a small gutter that directs rainwater to the grey downspout you can see on the left. Eventually I'll put some kind of barrel/container there to collect it. Right now we're experimenting with over-wintering some deck plants inside, but the full potential of the greenhouse will be realized in spring when I start seedlings for the vegetable garden. I also plan to keep some warm-weather herbs, like basil, in there all season; they should enjoy the warmth. The roof has two panels that open for ventilation. Those, along with the door that slides open (on the far end in the photo) and the door into the house itself (access to the utility room), will work to keep an air flow going so it doesn't get too hot in there during the summer. At least that's the theory.
