Read an interesting post at Worldchanging this morning regarding what is now possible and even essential that was once thought impossible. The post asked the question on a generic sustainability level at a Green Festival event.

It got me thinking though – what in the built environment is now feasible, possible or down right essential that a few years ago was deemed impossible?

Answers on a postcard.

Time to get interactive – so a call to all fellow bloggers (Mel, Phil, Pam, Casey, Mark ) syndicated blogs ( eg Eco City and friends at  Byoblue) and all the hundreds of readers out there… whats your ‘was impossible’ story?

I will add mine to the end of the comments.
