The problem of space layout in architecture: A survey and reflections

Abstract

This work is about the problem of Space Layout Planning (SLP) applied to Architectural Design. The creation of floor-plan layouts is key to architecture, and it is a problem that, because of its complexity, does not have a precise general method for its resolution. An overview and a wide description of the "Architectural Design" process are presented to understand this phenomenon. Secondly we present a brief history and development of the SLP field, and then a description of the state-of-the-art (techniques, approaches and strategies) to implement layout solutions. Concepts such as optimization, generative systems, artificial intelligence, genetic algorithms, physically-based modelling are reviewed and discussed. Commercial CAAD and BIM software is also reviewed. Conclusions and a discussion about the results and absence of this type of software for architectural practice are presented.
