When architect, Malek Alqadi combined astute environmentalism with his exquisite taste, he didn't just create this home, he sparked a revolution in sustainable tourism. Set on the edge of the Joshua Tree National Park, guests take the lead in operating this clean yet luxurious off-grid space. Think serious stargazing sessions through a telescope, showering by a boulder, and falling asleep under the desert sky with a crackling fireplace at your feet—the second bedroom is open to the elements, with no walls or ceiling. And it's packed with technology too. You can measure your energy consumption, change your light settings and set cooling and heating temperatures of the space. Wrapped in salvaged weathering steel and up-cycled details, it raises the bar on stylish, conscious travel.
