We started out by helping people design sheds, and quickly realized that many people actually want to build a backyard office. There wasn't really an easy way to do this, so we thought we'd take on the challenge.
Right now, you can design a backyard shed and our tool will make it code compliant. It's maybe 90% of the way there, since you also have zoning/HOA and other edge cases. But it does figure out most of the details for you. Right now, it's pretty simple: enter your address, what you want to build (i.e. 8x8 backyard office), and it'll create a few concepts for you. If you like one, you can customize it with the chat.
Here's an example of a design that's compliant in SF: https://myhomecat.com/scene/classic-cottage-137134ef
We would love for you to try our tool if you are planning your backyard office. As a bonus to the HN community, we can professionally design one for you for free if you comment what you're looking for.
Happy labor day!
