For retreat areas that you’ll use after sunset, include lighting in your design. Twinkle lights, outdoor lighting, lanterns, candles, solar lights—there’s definitely a light to suit your style. Consider combining different lighting options to give your retreat a dual personality—candles or twinkle lights for intimate gatherings or strings of larger wattage bulbs for entertaining. Built around a tree, this covered rooftop retreat features multiple lighting options, comfy built-in seating and even a bed for Fido. Pets like green spaces, too.
