If I owned my home, the first order of business would be building a Geo Kit pre-fab sphere-shaped treehouse in the backyard. Apparently, they're all the rage among Hollywood's rich and famous. They even come with add-ons, like rope bridges and ziplines! Wouldn't they make a perfect yoga studio, meditation pod, or playhouse? Perch it high in the tree and you'd have views for miles.
P.S. Until then... I'll be staying in this vintage dome house next time I vacation in the San Juan Islands.
