Greenhouse

My neighbor is building a greenhouse, using the old windows taken out of the house of his neighbor, who discarded then once the remodel began on his home. I have enjoyed watching the placement of the windows and once that was decided, how  the roof has finally taken shape. He is an avid gardner and I was surprised that he found enough space to erect this structure. My hope is, that once he runs completely out of room, he will expand his talents to my yard across the street :o)
