Final Fantasy XIV's 2.1 update, and in an article today Square-Enix provides a solid overview of what lodges and decorations will be available when the update hits.
While individual housing is still a ways off, free companies will be able to purchase a house once they attain a certain rank and get a land acquisition entitlement. House lots can be purchased in Limsa Lominsa, Gridania, or Ul'dah. Once a house is built, the exterior and interior can be customized and furnished.
The team expressed future plans for the housing system, including crafting workshops, customizable music, and chocobo stables. Housing will come when 2.1 hits on December 17th.
