The Final Fantasy XIV development team released a new video today showing off the still in development housing system planned for the 2.1 patch. The video only shows exterior creation, but it gives a good sense of how the system will function from an interactive stand point. The house looks to have slots players can drop components to change the house's appearance. It is likely that larger houses will have more slots. Afterwards, they show furniture placement which is a drag and drop type setup allowing for rotation as well as placement. It looks for the external there is a limit of 20 items, this may be dependent on the plot size.
