Someone upthread said the yurt wouldn't be big enough.
But - and someone correct my math - wouldn't the 30 ft be around 700 sqft of space?
That seems like a pretty nice size. Sewing area, longarm, stash storage, desk, small kitchen area, a cot for naps. I'd never leave. ;-) I'd visit the house a couple of time a week....to restock and pick up the mail.
Here's the gallery:

I saw a pic from another manufacturer where 2 were linked, doubling the space.
And Linzi Upton used a yurt to display quilts:
