It's 25m length but I have some buildings like a garage and place for woods. I need a space for kids so I'm planting mostly by the fence. Not enough space as my consider @gjones . And there is a lot of indoor plants. I need a green house though.
I don't over winter any plants in the house but in spring my dining room, front porch and part of my living room become a greenhouse! We start a lot of plants indoors to give them a long enough growing season. I'd love a heated outdoor greenhouse!
