One of Brooklyn’s most iconic artist studio buildings is in a precarious state after a five-alarm fire ravaged the 155-year-old warehouse in Red Hook late Wednesday night into Thursday morning. By the morning, part of the roof and the fourth floor had collapsed, and Van Brunt Street had flooded out. The building had taken on so much water from the firefight that it appeared to bow, sources at the scene said. For now, Red Hook business leaders have launched a GoFundMe campaign to help artists recover from the fire. “[Red Hook Open Studios] can still go on because there are artists elsewhere, but this is such a huge loss,” Suttles said.
