Trying to reach Ernie & Erica / "Annex" RMH plan question

Hi all, sorry for the "mass-mailing" but I'm trying to reach Ernie and/or Erica and haven't heard back in response to a few emails, so wondering if maybe there's an email situation happening.

I'm in the process of building a new house and am thinking their Annex design (http://www.scubbly.com/item/75761/) would do well in the space I have (on a concrete slab foundation). But I'm curious about the dimensions to make sure it will fit in a somewhat constrained space. Has anyone bought/used the Annex and can give me the dimensions?

In case it wasn't obvious, I'm new to RMHs. Thanks for any feedback/input!
