It seems many here are discussing the "coming impact of stressed green budgets on"....maintenance and aesthetics.
But, what about the "coming impact of stressed green budgets on architecture", as Pat posted?
I think that the deleterious effect on architecture is the perception that constuction and design must revert to the excessively and plainly designed golf course and its features.
R.B. Harris was in my understanding, the architect that took primary attention to maintenance budget efficiencies to the extreme and designed courses that would cost the least to maintain, at the expense of more aesthetic look and complex construction methods. That also effiected the strategic placement of his hazards.
So, if there is a coming stress on green budgets, due to drought, rising water costs, chemical cost increases, machinery cost rises, and continued high expectations for the superficial idea that green and lush is important, then architecture/design will drift back to the banal, it seems to me. Whether it is new construction or remodelling; creativity of design might suffer.
