Vancouver-based architect Michael Green was unequivocal at a conference at which I heard him speak a while ago: “We grow trees in British Columbia that are 35 stories tall, so why do our building codes restrict timber buildings to only five stories?”
True, regulations in that part of Canada have changed relatively recently to permit an additional story, but the point still stands. This can hardly be said to keep pace with the new manufacturing technologies and developments in engineered wood products that are causing architects and engineers to think very differently about the opportunities wood offers in the structure and construction of tall buildings.
