Greenhouse Dreams

Do you have a greenhouse?
I do not have one, and never really thought about getting one until recently. And by recently, I mean the past 2-3 years. Maybe it's because they are not those aluminum frame, glass ones of years past. There are so many styles now and ones that resemble a tiny home. 
I mean plants seem secondary in some. Furniture, chandeliers, rugs, sinks, and really more of a Mom cave. I dream of making it a sewing room. Just search Pinterest for greenhouse and a new board to create is an obvious step.
It's just a dream currently, but you never know, maybe I will find something for free or on marketplace to transform into an oasis in my back yard.
