This idea grew from the issue on how hard it is to get a house or get a larger plot. This suggestion would take a lot of work, but could hopefully allow more players to get houses.
Suggestion: Add wards for only Free Companies. A Free Company can unlock a ward dedicated to only their Free Company. They can lock it to keep people out or leave it open for anyone to visit. Any Free Company wards could be located in any of the city states we currently have in game (New Gridania, Limsa Lominsa, Ul'dah, or Kugane).
Ward Layout: The layout could be similar to the current wards. Or a different ward could be created for Free Companies.
Free Company House: A special plot, located in the middle of the ward, would start off as a small house on a large plot. As the Free Company grows, they can work to upgrade the house to medium or large or bigger.
Free Company members would be able to pick a plot in that ward to build their homes.
Initially, it would a small ward, but as the Free Company grows, advances, and gets more members, they would be able to unlock a sub-ward (similar to plots 31-60 we currently have). All these unlocks would be expensive, but for large Free Companies, it would give them something to work towards. Additionally, another perk could be to lower the cost of plots within the Free Company wards.
How will this help with the Housing issue in FF:XIV? Players would only be allowed to have a house in the normal wards or the Free Company wards. This would force players to decide if they want to live with their Free Company or take up plots for everyone else.
What would you do if you left your Free Company? Would you lose your house? Would you lose your house if you are gone for too long without logging in?
The player will have to relocate out of the Free Company ward or demolish their house prior to leaving their Free Company. If they tried to leave without relocating or demotion of their house, a message will alert them that they must first deal with their house.
For players who don't log in for an extend period of time? This is a tougher answer. Free Company leadership could trolls members who move into their wards by kicking them and the player would lose their house. Or if the Free Company is disbanded, the players could lose their houses. Therefore, for members who are going to be kicked, a message will be sent to the player that their Free Company is removing them and their house is in that ward. It will give them 60 days to relocate or demolish the house. This can also be used for player inactivity, for large Free Companies that need the plots and have inactive members.
For those who are inactive, putting their house/decorations into a 'holding area' similar to what there currently is.
Hopefully, with this idea, it will make more plots available to players who aren't in a Free Company or those who want to move.
