With a vague idea of "greenhouse" I started sketching ideas of what it might look like and how it might be used. I liked the idea of the greenhouse being a safe and creative space, in addition to being a garden. 

While I originally thought about showing the greenhouse from the outside, I realized it was the inside that mattered more. This was why I picked the bottom left image - it was more imporant to me to evoke the feeling of a safe and hopeful space, rather than showing off an intricate design.
