It's very cute, but you will be paying a lot for 'cute'! It's too small, and too short, and too expensive.

Definitely too short - those are kids in the photo. As an adult you'd spend every moment in there bent in half. And too small as well, the measurements include things like the porch which isn't chicken usable space.
I know where you're coming from though, I too considered getting a kid's playhouse and modifying it, but practicality won out over cute - paying extra for decorative trim and having no headspace to work with just wasn't worth it, when I could get a larger, functional, simple coop instead.
I would have no problem using a cedar shed/playhouse as long as it wasn't aromatic. My shed has some cedar trim and I also have aged cedar chips mixed in my litter and there hasn't been any issue, the aroma is very low.
