The restoration work has been limited to one specific area of Ishgard (the Firmament district) rather than a citywide effort of fixing up what already existed, sadly. Still very cool though!
Phase 1 of the restoration started in 5.11 with the zone in complete ruin:
We then had further phases in 5.21, 5.31 (all with multiple steps along the way) and the final phase which we're on atm which started in Jan with 5.41.
which brings us to where we are now, almost done:
Once this phase is complete (and thus the Firmament having been fully restored) we'll get a monument in there representing the crafting class which has contributed the most overall to our servers restoration effort too heh. Ultimately though, this is the Ishgard housing district we've been restoring so at some point in the near future (they haven't said which patch that will go live in) all of these houses you see will be plots for players to buy. Or try to at least to haha. Maybe we'll get told when that will be on Sat!
Always loved server-wide/contributed events like this (the AQ opening in WoW was another good one!). Hope they have another planned for the upcoming expansion
[Edit]
From the announcement showcase stream:

Will open in 6.0 to walk around in and you'll be able to buy a plot in 6.1
