Hopefully for Possible Upcoming Instanced Residential Spaces.
Bigger Vertical and Horizontal Spaces.
"Fully customizable with furnishings like pillars, beams, dividers, and lofts panels specially designed for that area only, so the owner of the space will have more designing options at his/her disposal."
Wide Instanced Balcony Areas Following day and night cycle and weather conditions Allowing Indooor Gardening
"A possible starter home sharing a common residential building and lobby with other home owners, but with amenities like chocobo stables that are always clean, beautiful landscapes around the building, as well as all sorts of npc vendors around the establishment, the building itself can be seen from a distance, and with its own aetherite.

so it can be accesed by flying or porting to it, but most of all it is readily available for everyone, as the design mechanics are already existing"
Utilisation of Spare FC Private Chambers
Many people complain that their FC can't get a larger home on the basis that they have too many members for the floorspace afforded by a smaller house, and/or the item limit hinders decoration when accounting for specialised 'zones' (crafting boost items for new crafters, kitchen areas with a variety of laid out meals, etc.). The solution many find is to sacrifice the private chambers of some members to make additional communal areas, and/or making alts just to join the FC, buy a room, and 'hold' it to serve the same purpose.
With up to 512 private rooms, unless it's an excessively large FC, that's a lot of rooms unused that could be. However, under the current system, to take even partial advantage of that, you either need to have a lot of placeholder alts between you, or recruit a lot of people you have no intention of playing with on the condition that they sacrifice their rooms.
Ideally, unclaimed private chambers could be unlocked by members who already have a private chamber of their own, to be used as FC rooms. Similar to purchasing a housing plot, where you designate purchase as an individual or for FC, when the member goes to buy the private chamber, they can opt to buy for personal use (same as current system, limited to one per character per house they're a tenant of) or buy for FC (limit to one or two per person, or some other reasonable limit).
Purchase private chamber for FC would require the same rights as purchasing a plot for FC, so the leader can limit it to themselves, or just officers, to prevent the place running out of rooms for new members if it's a large FC and every member does it.
Rooms purchased as FC rooms would bear the same ownership rights as the main estate, eg moving/removing decoration within the room requires FC rights to do this for the estate, access rights default to FC Only and can be toggled between that an Public but never locked to any individual. However, they are 'maintained' by the purchasing individual, and so would be destroyed upon that individual leaving the FC or deleting their character (hence restricting rights to purchase to trustworthy individuals).
However, these rooms would also retain the features of private chambers, such as the restriction against placing aether wheel stands, separate item count from the main estate, etc. So they don't need new coding on the function other than the different access settings.
This would give a lot more space to FCs to utilise, mitigating the need (real or perceived) to upgrade to a larger plot just to get more space. It would also take away the expectation that the Leader and possibly Officers are subject to now, that they sacrifice their own room for an additional FC room. Furthermore, it would allow for thematic/RP options, where the estate can be open to the public, but certain chambers can be locked to non-members, eg an FC office room or treasure vault.
This may increase server load, as I presume the majority of FCs don't come anywhere close to the 512 limit as it stands currently. However, I would presume that this limit was set with the expectation that it may be utilised, and so it shouldn't place more strain than what was originally anticipated. And it would certainly be less stressful than finding a way to add more large/medium plots to wards, or increasing the item limits significantly on plots (both things that have been heavily requested, with a large portion of the supporters of each idea doing so due to the limitation of the size of an FC house and the lack of expandability within it as needs grow).
