Experiments in dense, but attractive housing are probably the gatekeeper to affordable housing. I don&#x27;t see this talked about much. Affordable housing is a good goal, but until it can be done in a very dense way, it cannot compete with other schemes. One idea I have is to run genetic algorithms to create housing schemes that would seek to maximize sunlight, and privacy. The plan needs strong focus on sound proofing and technology to reintroduce ambient sound when desired. The plan would also balance the exposure of inhabitance to each other in their comings and goings and in their use of common areas. Finally, the scheme would seek to keep public as much of the area as possible to make it competitive for commerce and livelihood compared to other parts of the surrounding environment.
