In the months since, Voloshin has been awaiting and analyzing an engineer’s report to help determine the feasibility of his proposal. Nearly 2½ years ago, he estimated that structural restorations would cost nearly $1 million. On Tuesday, Voloshin said that he is still trying to “figure out whether it’s still affordable or not, given the size of the structure and the number of apartments that we are able to put in there.” He declined to say how expensive restorations would be today, though he noted that construction costs are now more expensive.
