Holy cow!.... Two things: those retrofits
WERE done improperly and are a leak waiting to happen. Secondly, based on what I see, a retrofit
CAN be done effectively, just not the way those other hacks did it. It looks like you have a solid 4" (or so) drywall return. The new window can either set inside that, or the drywall can be cut back to butt against it, while keeping the window inside the opening. There is no reason at all to push a window so far out like that.
A full-tearout, new construction install would probably be ideal, but it is not necessary.
... Based on my experience, I cannot even believe that a condo assoc. let that pass.
