Mass Customization of Housing: A Framework for Harmonizing Individual Needs with Factory Produced Housing

Integrated processes for design and fabrication have guided mass customization of architectural systems and components. Providing affordable and accessible housing, a vital segment of the building industry, is a multifaceted process that witnessed various manifestations towards individualization over the past few decades. Design flexibility in housing systems is becoming a crucial aspect, informed by consumers’ lifestyles, demographic patterns, and lifecycles change at a rapid pace. As the housing market demands more personalized, efficient, and agile strategies, prefabricated building systems have always presented a viable alternative for flexibility and cus-tomization, following a rise of interest in the last decade focused on new modes of digitized design and production. This paper presents an overview and appraisal of various practices to implement customization in the housing industry, with specific focus on empowering a systemic approach. We then propose an open framework that could accommodate emergent design technologies and production protocols, with the aim of taking advantage of advanced research efforts, and coupled with current industry application

Customized housing design: Tools to enable inhabitants to co-design their house

In architecture, the individual needs and preferences of the end users need to be achieved in order to ensure a successful design. Standardized houses have been for long the reason for inhabitants' lack of satisfaction. The participation of inhabitants in the design process of their own houses is a crucial aspect to address housing customization, however there is a lack of effective tools to help inhabitants co-design their houses. Generative design solutions seem to be an effective way to address mass customization problem. In this paper we present a literature review on computer aided design systems that allow inhabitants to design, or partially design, their own houses. Existing solutions are classified in several categories (as generation process, target users, type of outcome, type of interaction, availability) regarding to what they accomplish and then analysed.info:eu-repo/semantics/publishedVersio

Interactive constraint-based space layout planning

Layout planning is the primordial design activity that determines the characteristics and performance of a building throughout its lifecycle. Due to its iterative nature, there is a growing interest in the automation of space layout planning to enhance the search for optimum design solutions. The approaches for automation range from constraint/heuristics-based to the application of numerical optimisation algorithms. Among these, the use of design constraints to guide the search of the solution space is well regarded due to its ability to model design problems of an applied nature with multiple objectives. Constraint-based approaches also allow interactivity between the designer and layout planning process, which simulates the iterative nature of creative design and can be integrated well with the existing design process. Interactivity also enhances the management of design knowledge through improved processing and visualisation of information. This paper presents a theoretical framework for interactive constraint-based layout optimisation with an implemented prototype for a hospital patient room interior layout. The theoretical framework was developed by analysing existing layout automation methods and interactive approaches through a review of relevant literature. Object-oriented computer programming was used to develop the prototype to demonstrate the proposed approach of interactive layout planning system. The framework augments the iterative design process by facilitating the active participation and sharing of the designer’s knowledge during the aggregation. With regard to the implementation of the framework in large problems, fast evaluation of design solution was found to be necessary to interact with the system in real time. Interactive constraint-based layout optimisation has, therefore, the ability to enhance the search process of optimum design solutions by augmenting the iterative nature of the creative design process

O problema da distribuição espacial na arquitetura: pesquisa e reflexões

This work is about the problem of Space Layout Planning (SLP) applied to Architectural Design. The creation of floor-plan layouts is key to architecture, and it is a problem that, because of its complexity, does not have a precise general method for its resolution. An overview and a wide description of the “Architectural Design” process are presented to understand this phenomenon. Secondly we present a brief history and development of the SLP field, and then a description of the state-of-the-art (techniques, approaches and strategies) to implement layout solutions. Concepts such as optimization, generative systems, artificial intelligence, genetic algorithms, physically-based modelling are reviewed and discussed. Commercial CAAD and BIM software is also reviewed. Conclusions and a discussion about the results and absence of this type of software for architectural practice are presented. Key words: space layout planning, computer-aided design, automated architectural floor layout, design methodologies.O artigo trata do problema da distribuição espacial em planta (SLP, por sua sigla em Inglês) aplicada ao projeto arquitetônico. A criação de desenhos de plantas é uma questão fundamental e, devido à sua complexidade, nenhum método preciso para ser resolvido. Apresentamos uma visão geral e uma descrição detalhada do processo de projeto arquitetônico para compreender esse fenômeno. Em segundo lugar, apresentamos uma breve história e o desenvolvimento do SLP. Em seguida, trataremos sobre o estado da arte (técnicas, abordagens e estratégias) para implementar soluções de design. Os conceitos de otimização, sistemas generativos, inteligência artificial, algoritmos genéticos e modelagem com base na física também são revistos e discutidos. Também são analisados os softwares comerciais CAAD e BIM. Ao final, apresentamos as conclusões e uma discussão sobre os resultados e o impacto deste tipo de software na prática da arquitetura.Palavras-chave: planejamento de distribuição espacial, design criado por computador, projetos arquitetônicos automatizados, metodologias de design
