Curvilinear architecture is a design style characterized by the use of curved lines and organic shapes. This approach often contrasts with traditional angular structures, creating a more fluid and dynamic appearance. Buildings designed in this style can evoke a sense of movement and harmony with their surroundings. This architectural style is often associated with modernist movements and can be seen in the works of architects like Frank Gehry and Zaha Hadid. Curvilinear forms can enhance the aesthetic appeal of a structure while also improving functionality, as they can create more open and inviting spaces.
