Clearly, if you establish a preference for one building material over others, then that is inherently a disincentive to take a look at.... I'll use the example of a building design that fundamentally frames the building or completes the structure with steel or concrete or an alternative construction material. There is an inherent competitive imbalance in saying we give preference to wood construction.
As to increasing costs, generally the way these things work is that, once you've introduced an inhibitor as far as competitiveness is concerned, you introduce a cost escalation. That's what logically follows. There may be instances where, in designs or projects, there would be a more economical path to take with steel or cement or whatever sort of combination solution, which could include wood, but if you were to give preference to wood, you might see an elevated cost that way.
