Raulino Silva Architecto built a hotel for pets in Parada, Portugal. As shown in the photos, this seems a lot nicer than most human hotels, and the accommodation for the dogs and cats are extraordinarily remarkable.
I believe that when the pets are left alone at a hotel, they deserve the option possible, which should be reflected by the comfort and affection they are provided with not a fancy exterior or beautiful architecture that attracts the pet owners. If all is well equipped, I believe design and architecture can play as a significant factor to assure their customers and market their potentials.
