Very happy for you.
The first thing we did was slap on three coats of termite paint. Then we just left the doors open to air out because that stuff is nasty. Next week we will start all of the extra framing supports and electrical.
I read where the floor is the very last thing to go in and be finished so you do not get it all messed up doing the walls. When we are ready for the floor we will put down sub floor and then tile over it.
This will be very interesting to see how you do yours differently from how we do ours with both of us ending up with nice little studios.
