Jane and Jerry Mount are the lucky owners of the Green Playhouse.

The custom-built keiki playhouse, built by Pai‘ea Millwrights and Philip K. White & Associates, was auctioned off in May at Hawaii Nature Center's green gala.

The playhouse is made of recycled redwood, cedar, fir and luan. It's outfitted with a small photovoltaic panel on the roof to power a bubble blower on the composite Trex lanai. It also has a rain catchment bucket to help water the little WikiGarden.

It's a way to show keiki sustainable living.

"Hawaii is a place where we have the option to build very lightly and still have some comforts," said Logan Pai‘ea White, founder of Pai‘ea Millwrights. "Refinement can always be added through emphasis on design, functionality and creativity. The playhouse is a model of these values."
