Blue Jean insulation, the City's first residential rainwater catchment system, and fly ash concrete (we love it so much) contribute to 520 Clipper's designation as the "greenest" in SF (and if not, most definitely the greenest in the ever-earnest and lovely Noe Valley where Avenue finds green to be oh-so-compatibly located).
What did Lorax Development's 4BD/4BA work list at? At $1.89M, 520 Clipper asked a competitive, if not high, $730/SF. (Construction costs were estimated at $350/SF.)
