The architecture of leisure tends to be one of the best exponents of the creative capacity of the designer. The functional and aesthetic limitations are almost always less strict than in other areas, and this is why the most famous spaces of clubs lounge bars and discotheques have become fundamental examples for studying the different tendencies of language, materials and design that arise from the interior design of this century. This work presents twenty interior spaces designed by renowned architects and designers, in which diversity and ingenuity are the most outstanding features for spaces that are an invitation to fun, imagination and relax.
