The book contains general descriptions about features of museum design as well as a summary of project design process which was selected and rewrote from M.A. thesis of the students. The book is consist of explanations about methods and design elements of spaces such as museums, cultural centers and projects with themes like digital museum, children museum and garden, art museum, music museum, theatre and structures like parasite pier and bridge. Meanwhile one of the salient features of the book is that it offers new ideas about facade design and samples based on Iranian and Islamic patterns for spaces like museums and exhibiting spaces. Taking benefit of design process and being bounded to it, similar to other books, is really important for me in this book, too. As it is seen in the projects, conceptual sketches play important role in this process. Conceptual sketch stage is related to embodiment of ideas and thoughts formed in architectural imaginations. However, they are not sufficiently clear and the sketches help them to express themselves better. Conceptual sketches of these projects are not merely limited to manual design; rather they are presented as 3D models in computer or volumetric works using 3D pens or prints. At this stage, there is a traverse between manual sketches and modeling. The sketches are modeled with a new perspective or designed based on 3D models to enrich their volume or space. This traverse which is regarded as a transversal movement during the design process is of special importance. I call it interaction between design and computer . This book is a software-aided design practice trying to reach a better perception and recognition of Iranian architecture and modern achievements of western architects. In fact, the book demonstrates the process of transition from manual to digital design in a country which was far from most software and technological progresses as well as essential trainings.
