gorgeous internal atrium garden... just lovely!
Atrium Garden - enclosed with low wall
I don't like the plant choice or the sparseness of this atrium, but I like the floor to ceiling window. I would prefer something more naturey and thicker stone/wood pillars inbetween the glass, but this is a good ref to keep in mind nonetheless More
Court yard garden. A tree in the middle of my house would be so cool, especially with a green roof and built into a hill.
Greenery wall - I really like this concept, but I don't really know about maintenance?
