Do you support 2 story homes?

Doesn't look like it. From their FAQ: "Drafted is focused on single-level floor plans today. Multi-story homes, second floors, and basements are in progress and expected to become available soon."

I'd love to see a two storey use case in the future! I have a few designs for a small plot of land in Toronto (2500 sqft lot) and would love to try and make alterations based on my zoning constraints.
