As a quick follow-up to Alex's post the other day about the mainstreaming of green home design, the Guardian reports that a recent survey of British would-be home buyers resulted in 87% wanting substantial information about the environmental aspects of the homes they considered, and 84% were willing to pay an additional 2% (a seemingly small amount, until you consider how expensive homes are) for an "eco-friendly" home. It's not just mainstream home designers who are starting to think green -- mainstream home buyers are, too (at least in the UK).
