    Playa Langosta, Guanacaste, Costa Rica

Casa de Luz, The House of Light, is a stunning beachfront retreat on the white sands of Playa Langosta on Costa Rica’s north Pacific coast. This luxurious 7,200-square-foot villa, designed by renowned architect Abraham Valenzuela, is exclusive, secluded and environmentally sustainable: solar roof panels and a power plant supply the entire property’s energy needs. There is also a  backup water system. An ocean-facing infinity pool, palapa bar, tropical gardens and tide pools shaded by mangroves are added highlights of this oceanfront paradise.

Camp Endo (also pictured top) is a private 417-acre mountain kingdom threaded with trails and ridgelines, minutes from Stratton. The 9,539-square-foot main house reimagines the classic mountain lodge for the 21st century, offering complete comfort, great light and welcoming spaces. Campo Endo also embraces sustainable living: a combined wind and solar power plant provides 22 kilowatts of renewable energy. There are six en suite bedrooms, a gym and spa, meditation room, theatre, screened-in porch, and a deck with spectacular mountain views. This one-of-a-kind property also includes a barn with guest quarters; a heated half-basketball court; a swimming pond stocked with trout; an orchard; paintball course; and a six-foot square chessboard in the forest.
