There are similar projects to Autoarchitect. They usually approach the problem from slightly different perspectives. For this post, I will be talking about some of them, in addition to some related research.

Towards a Scientific Architecture - Yona Friedman

In his book, Friedman mentions a proposal for what he calls an "apartment writer". He cites the Tyranny of the Architect, the tendency of architects to advance their own ego over their client's needs, as a major problem, and proposes a new task for Architects and Planners. Mainly this: design should be treated like a restaurant menu, where there is a repertoire of architectural elements the client can pick and choose from. Every item has a warning that is either the food combination or the price. The role of the Architect becomes like the Chef in that analogy: to organize and curate the repertoire. Here it is in Yona Friedman's own words:

This example demonstrates the method that propose for setting up a repertoire for the architect’s client to use. The repertoire will be made up of a complete list of all the possible linkages and labeling (the mapping of the problem itself). The client (earlier we called him the future user) will actually have the freedom to choose any possible combination instead of having to go along with the preferences of some architect or other.
For each possible combination, the repertoire will have a corresponding warning indicating its cost. The warning will tell the client the cost expressed in effort; this is the intrinsic property of each combination, that is, the advantages or inconveniences of this combination in terms of the client’s particular mode of use.

Other authors have echoed Friedman's sentiment, like Nicholas Negroponte in Soft Architecture Machines (a part of which Friedman introduced). Negroponte frames it under the title User Participation in Design. He separates the field of user participation into 3 categories: more info, more advocacy, and the part least protective of "professionalism", citing Friedman: control. The two categories are not really considered participation. He likens the traditional architect-client relationship as Paternalistic, as follows:

Father knows best for a long time. However after a while he begins to lose credibility rapidly. Inconsistencies and unexplainable “musts” make the original institution of paternalism more and more suspect to a child; the doubt probably starts as early as age one or two. Nonetheless, for a long time the issueof Father’s rightness is less important than the comfort of knowing he is around. In this sense, it is interesting to question the role of the architect in terms of comfort and confidence; can it be embraced in a machine and thus avoid the potential orphanage of participation?

An adaptive approach to residential design - Bruno Postle

A Pattern Language, published in the late 70's by Christopher Alexander, tried to envision a brave new world for Architecture. It defined a series of "patterns", or rule sets, that encapsulate what is according to him good design principles. It encapsulates Architecture, and by extension any design process, into a series of individually and scientifically testable rules, which can be taught and expanded on and adapted. While the book was more or less a dud in mainstream architectural circles, it became a huge influence on the field of software design. Coders and designers came to define their own design patterns and use them as a guide for good and efficient software design. One programmer, Bruno Postle, figured he should take the idea back to Architecture through an algorithm called Urb.

Postle used genetic algorithms to produce plans and designs for residential houses, using Alexander's patterns as fit criteria. In other words, the algorithm generates thousands of house designs then basically picks the one that satisfies Alexander's patterns the most. Every individual pattern was assigned a score, and each generation was scored by all the patterns, and all the scores were multiplied. The higher the product, the better the house is in theory. The algorithm, when applied to generate cities, seems successful as replicated traditional house designs. The project is written in Perl (for some reason) and is open sourced. It can be found in its homepage.

Housing Agency System (HAS) - Architecture Research Lab

This is an attempt to solve the problem that most houses designed are designed without paying attention to the eventual resident. The only party with input into the design is the developer, whose best interest lies in having the exact same design for all the houses they build. HAS tries to find a compromise between developers' needs and clients' needs, by creating a a mass-customizable house design that can be customized by the buyer using very simple criteria, such as the shape of the site, the existence of a car, and so on. This affects items like how long the rooms are, the angle of certain joints, the number of floors, all within a ready design structural system that can apply to all these solutions. More details about the process can be found in their website.

To end this post, I would like you to ponder this quote, while thinking about the status of typesetting in today's world:

The writing of this book was completed in the summer of 1972. By fall it had advanced to a computer-readable format (paper tape). It is appearing only now, in 1975, for a number of reasons related to its production. The author and the publisher share the embarrassment that most of the delays were caused by the use of automation, in particular, computerized typesetting. The only redeeming aspect of this episode is the shared belief of those involved that, while this is a feature of computerization today, it is not an inherent and everlasting property.
