In the age of digital revolution, architects have to keep pace with latest advances in technology and computing, which in turn affected architectural design and fabrication. In architectural form finding process, some schools of thought encourage personal inspiration, intuition of the architect and his sense of beauty, while others depend on specific design approaches based on rules and fulfillment of design requirements in generating architectural form. This paper presents a review on various form finding philosophies that have been existed in architectural design over the past century till now. In addition, a taxonomy for digitally generated forms is presented herein into two categories. Through investigating these different approaches of form finding process, some of them focus only on the qualitative and aesthetic aspects of the architectural form and didn't take into consider building performances such as functional, environmental, structural or acoustic, while others focus on the performative aspects. Moreover, dealing with the current complex geometries and advanced technologies made it important to depend on an Integrated design: a Generative performative design Approach that achieves balance and takes into consider both aesthetic aspects as well as the performative considerations of the building such as functional, environmental, structural or economic, in order to find the optimal solution at early stages of the form finding process.
