Great to hear!
To add to the thread: since we are talking about builders, one of the main services that Pronghorn offered (besides building) was CAD design of the interior. They will help put together the plan you're imaging and confirm that things will or won't fit. They can even go into accurate materials lists and working plans to build off of. That was really helpful to ensure things would go together as I'd imagined as well as confirm the sizes of things we wanted "should" work. Andrea will tailor the level of detail (and associated cost) to your budget and interest.
I assume that other shops have CAD available or in house, but I can confirm that Andrea at Pronghorn does great work. I was able to order all my 80/20 and wiring off her plans and just have some peace of mind knowing that as long as I do my part building out the interior, things should go ok.
Also, the I did not mean to imply in my statement "they are in Alberta but..." that somehow someone from Alberta is suspect lol. I need to proofread a little more I guess.
