Today in limited fashion, Crafting Cottages were released (not all players have access yet). Farm Ville Freak Farmb0y was lucky enough to have access and already built his Spa Crafting Cottage.
It appears that Crafting Cottages will work on a star system much like crops and storage. You will have the option to upgrade for coins OR $FV. For the Spa it looks like as you upgrade your building you will have access to more tables which will allow you to make more goods.
