Artificial intelligence (AI) is becoming increasingly ubiquitous in the architectural industry leaving many architects wondering what the creative future of the profession looks like. With a focus on aesthetics, this thesis introduces a handbook for the posthuman architect. Through working examples it details how algorithms and networks can generate novel concepts developed synergistically with human creativity. This framework places humans and machines together in an ecology of design and encourages the architect to think of their relationship with AI as that with a cognitive collaborator rather than a tool. In doing so we may be able to foster a planetary architecture that promotes the inclusion of all participants of our ecosystem; cognitive and non-cognitive alike. In this way, we can create engaging and inclusive architecture in harmony with our environments. The future of humanity and architectural practice looks exciting if we are willing to embrace the technology to which we have given cognition.
