In my original comic, Dreamcatchers, the main character Jubilee has her own greenhouse above her room. Before showing it in the actual comic, I first came up with the exterior design and how it'd be positioned by/above her room.

The outside of the greenhouse (or specifically its roof) is first shown at the end of chapter 2. A portion of the interior is shown later in chapter 6 which I had to design as well; this includes not only aligning the windows structure to match the exterior but the overall set up of the inside. I studied greenhouses, what to grow in a greenhouse, at what seasons to grow what, which vegetables (and fruits) can grow together in a greenhouse and the watering systems used. It was tiring but satisfying as well.
