What architectural style is characterized by an experimental approach and often combines different styles?

The Postmodern architectural style is known for its experimental nature and the inclination to combine various architectural styles and elements. This approach emerged as a reaction against the strictness of modernism, which emphasized minimalist forms and functionalism. Postmodernism allows for greater creativity and playfulness, often utilizing historical references and eclectic combinations of materials, colors, and forms. Buildings from this style might incorporate classical elements, unexpected shapes, and varied textures, creating structures that are visually rich and often whimsical.

This characteristic of blending styles is one of the hallmarks of Postmodern architecture, making it distinct from the other styles listed. Beaux Arts, while ornate and historically informed, adheres to a more rigid classical language. The International style focuses on simplicity and functionalism without the playful experimentation seen in Postmodernism. Brutalism, known for its raw concrete forms and sculptural quality, does not typically incorporate diverse architectural styles but rather is characterized by its stark, monolithic appearance.
