Composing Architecture and Interior Design introduces different ways of creating architectural space, based on controlled transformations of physical models. It explains how to compose architectural spaces step by step and can be used from the first years of architecture and interior design studies - and beyond. This book demonstrates how generative design can be applied in architectural practice, regardless of having any knowledge of digital design software. If explained in one sentence, the base of generative digital design is the design logic of transformations. The book starts by introducing different spatial configurations using basic elements, being walls, floors and ceilings, in order to create spaces with different architectural qualities, such as collective or transition spaces. Throughout the book, the most contemporary approaches of composing space, such as folding surfaces or combining curves are explained step by step with diagrams and physical models. Each chapter begins with a globally acknowledged, built project.
