Móyòsórè “Moyo” Martins moved his workspace into this 3,000-plus-square-foot studio in Mott Haven in December 2021. He’d been working from his Harlem apartment and using a bedroom as his studio. But things had become cramped. Then he found this space in a former furniture factory on the Listings Project. It took two months to clean out. One thing it also had — lots of natural light from the windows and the six skylights — would have seemed like a bonus. But Martins painted them black.
