Everything started with my fascination of Pokémon-Go; the cultural moment when the building environment was used differently than intended; massive groups gathered around in public parks and kids invading your backyard. I wanted to understand the behavior of people and the new ways of interaction between space and humans. Literature research helped defining different fields of game-theory and architectural space, and most importantly the relationship between those. It gave the knowledge needed to do observations and make new conclusions. The results were descriptions of spaces where the situation of the Pokémon-GO effect occurred: playgrounds. These playgrounds were spaces where the players could be free and use their imagination to build their own world, where humans can be playful. With my design I intent to have the same methodology as these playgrounds.
