I am always a fan of patterns and prints on buildings. Although it is just external, it makes the building stand out from its surroundings. Take this Companies Incubator at ArchDaily designed by Manuel Craca Dias + Egas Jose Vieira. Who can ever thought that tiles are so in? In this case, it is soooo OUTside. Move over Bisazza! It feels clean and fresh, put a smudge of mud..you have a skid mark then voila! you have a toilet palace! It is clever how the designers alternated the patterns to really veer away from the traditional checkered pattern. Had it been like that, it would have made the building interactive. We can play chess and TIT tac toe.
