Perfect for an ecotastically-pampered pup, this (new) home is topped with a top-of-the-line garden of its very own! Each of the Greenrrroof animal houses are carefully created with a special vertical extension to hold plants and flowers. This roof system can provide insulation against chilly temps and annoying sounds as pup tries to sleep as well as filtering runoff water and dust. These sustainable pet designs attract butterflies along with those pet owners that want to have the best (dog) house on the block. The concept homes start at $1,000 and range up to $6,000, so check them out close up when you read more.
