This Woodside, California owner wanted a new swimming pool, with an automatic cover that would retract out of sight when open, an adjacent spa that would be hidden under a retractable deck when not in use, and a heated fountain with a waterfall one could stand under when in the spa!  The pool, colored a mountain lake deep blue-green, is bordered by granite paving stones on two sides.  The cover rolls under the wood deck that borders the pool’s other two sides.  A section of wood deck rolls under an upper deck level, using garage door hardware, to reveal the spa, whose  water circulates up to a fountain above to spill down in a heated waterfall.
