This research focus on the development of computer implementations for shape grammars that enables to generate customized design alternatives based on specific design languages.
Two different implementations for the design system are under development. One based on shape grammars supplemented with processes detaches shape knowledge from procedural knowledge. The exponential nature of the search space led to the need of employing different effective search paradigms such as genetic algorithms which are used in a second implementation.
The systems under development are based on shape grammars and will allow future owners to acquire houses that fit their needs while simultaneously complying to a language of design. Such a system will enable to deliver design solutions at affordable prices improving satisfaction of clients and their quality of living. The system encodes knowledge on housing design principles (sizes of rooms, types of rooms and there preferable connections) as well as in the timber construction technique that underlies the shape composition principles.
To make the system available for future inhabitants a computer implementation – Alternative Shaper – is being developed so that it could be made available online or at the housing construction company. The design tool will: i) deliver design solutions answering the client’s’ requirements based on a design grammar therefore maintaining a language of design, ii) be feasible to be used by non-designers.
Shaper-GA is a Genetic Algorithm (GA) approach to produce automatic designs for modular houses. A set of architectural design rules defining a language of design is incorporated into the GA fitness function. When possible genetic drift or local convergence might be occurring, the method starts an adaptive mutation rate to overcome fitness stagnation. The GA tool efficiently produces several layout solutions obeying the design rules and further placement constraints.

|2018||Outro Evento||My House Designer||Demo in the event "Ciência 2018". My House Designer aims at the development of computer aided design systems that automatically design house layouts according to the inputs given by the user of the system, namely the inhabitants. We are developing two different computational approaches, both based on shape grammars: A_Shaper (procedural knowledge) and Shaper_GA (Genetic Algorithms). The aim is that both implementations can generate design alternatives for housing layouts that correspond to the need and wishes of inhabitants. With such a system, inhabitants can be part of the design process of their own houses. The design system could be made available online so that future inhabitants could access it, play with it by introducing their needs and then generating housing design solutions.||Filipe Santos, Sara Eloy, Bruno Taborda|
