This is the first sign of the floor-to-ceiling glass wall for the 9-story office building at 141 E. Houston St. ... as the construction netting has dropped a bit here between Eldridge and Forsyth.
Completion of the 65,000-square-foot space is slated for the fourth quarter of 2021, per the 141 website.
Our previous post (here!) on No. 141 has more details about what's been happening here to date at the site of the former Sunshine Cinema (RIP January 2018).
