Riyadh is the capital of Saudi Arabia, with a population of 5.7 million. It is one of the least dense cities in the world, at 2,500 /sq.mi. (Dubai is 6,863. Istanbul 7,060. Los Angeles 3,189. Chicago 11,864.) There is no public transport available, but they are working on it.
Yet for a city with so little density and that is literally in the middle of the desert, it is currently in an ongoing housing crisis. 50% of residential units are of the typical "villa" type, which means a walled, but not wall to wall, 2.5-story house. Land available to buy and build is too scarce, leading to an increase in prices as the demand for houses rises, while income remains largely the same. Land that is available for sale to build on is becoming smaller and smaller.
This has prompted a research project in my first semester in SAIC : an investigation on how Houses grow. Starting from the simple observation about how houses of the Middle East grew historically with their families, I speculated into how could that be applied to the Riyadh houses of today. It started with an analysis of a typical Riyadh house and the rules and patterns that generally govern it. The rules had to written in a way that allowed potential extendability in the future.
In addition to speculation about how could a single house grow and how the neighborhood would grow with it. For the case study, I took the house I grew up in, and imagines a past and a future for its extendability, spaced over the typical growth of a Saudi family, based on a study by an undergraduate classmate, Ahmad Alfarhan.
Eventually, this the original exercise led to the first prototype of Autoarchitect. A genetic algorithm was created to design house based on the number of family members, and a typical program based on earlier research. The prototype, while not including doors and windows and staircases, accounted well for rooms that intersect with each other and sent rooms up to the second floor as needed. The only problem is that it took a long time and the result was nowhere useable.
This was, in a nutshell, the first version of Autoarchitect. In the next blog post I will share some of prior art and some of the writing on the subject that influenced me then and later.
