All is well at Structure Tone’s new Manhattan headquarters at 330 W. 34th St. The construction services provider’s 82,000-square-foot home base recently obtained a WELL Certified Silver rating from the International WELL Building Institute (IWBI). The headquarters’ new designation makes it the inaugural project in New York to secure WELL certification under the WELL Building Standard, the first performance-based system for the measuring and accreditation of the built environment’s impact on human health.
