This elegant Washington, DC, garden unites the timeless elements of water, stone and plants with simple, clean lines to create a tranquil, urban retreat with Asian flair. An expansive koi pond comes right up to the living room’s floor-to-ceiling glass doors, which gives the impression of the house floating over the water. The line between interior and exterior space is nearly forgotten as the full light and beauty of the garden bathe the cozy interior world and become part of it. Blue stone steppers float across the water into the landscape, beckoning further exploration. The pond is dappled with water lilies and the flickering colors of the koi bringing their own magic to this stately landscape,which is surrounded with Japanese maples and jeweal-like conifers.
