Blackstone agreed to acquire Flatiron Park, a 22-building complex, for $600m. Flatiron Park devotes about 15% of its campus to life-science tenants, including biotech firms like KBI Biopharma and Enveda Biosciences. BioMed Realty said it believes that eventually half the campus could be filled with life-science businesses because of intense demand in Boulder for specialized lab and office space.
