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 customization, 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.

The Abu Dhabi Government has recently devised a program to promote sustainability guidelines and regulatory tools within the AEC industry in the UAE. The program; known as Estidama, proposes a set of strategies to ensure sustainable practices from design to operation, and maintenance for all building typologies and communities across the UAE. Currently, the Estidama Design Guidelines have been directed towards new construction of residential and commercial buildings. Nevertheless, it is evident that existing buildings and other facilities should be considered in the future within the program's appraisal given that they represent a large percentage of Abu Dhabi's built environment. This research addresses the status of the existing residential stock in the UAE built environment, which included around 185,000 units by the end of 2007, prior to the Estidama initiative. We analyse various contextual characteristics, then propose a methodology to integrate effective sustainable refurbishment strategies to capitalise on the scope of Estidama's guidelines with the aim of potentially including a chapter for buildings overhaul in Abu Dhabi. We strongly believe that this research would be a valuable addition to the Estidama guidelines, and could compliment the Abu Dhabi Vision 2030.

The provision of national housing to citizens in the United Arab Emirates (UAE) is considered a crucial topic. Over the past four decades, the process of developing national housing has emerged into multiple housing programs and schemes, all with the same aim of offering affordable and high-quality housing to citizens, in addition to meeting the needs of local families regarding spatial configurations while maintaining cultural values. However, despite all these efforts, the question has always remained: are the offered housing practices suited for family needs, socioeconomic trends, and environmental challenges? This study aims to offer an alternative approach for the design and delivery of national housing practices in the UAE. The proposed process is structured based on the following ethos: first, a conceptual approach for design flexibility toward offering customization while maintaining contextual and cultural qualities for inhabitants; second, a computational design strategy for facade optimization that illustrates the significance of incorporating environmentally conscious design strategies in response to local climatic conditions toward enhancing overall building performance; and third, a hybrid production model that relies on a prefabricated building approach that combines precast concrete systems with 3D printing technology. The efforts described in this article represent a significant phase of an ongoing research endeavor that explores how technological capacities could help rethink national housing in the UAE.

The concept of employing web-based configuration systems towards mass customization of housing has been implemented by some prefabricated housing companies around the globe, and has become a challenging research area in the last few decades as an outcome of advancements in communication and design technologies. Different methodologies have been employed with the aim of efficiently engaging future homebuyers in the design of their homes. The thrust of this paper is to systematically formalize an advanced configuration system for mass customization of prefabricated housing for a company operating in the Canadian market. The focus is on one floor bungalows which are common within the Province of Quebec. Such housing models targets a specific market sector; elderly couples seeking retirement homes, with the aim of improving affordability through maintaining particular design and production qualities.

Purpose: The purpose of this paper is to propose a novel framework and a systematic group of methodologies for constructing a computer-based design system that could support homebuyers’ participation in the design of their dwellings in the UAE housing market. Design/methodology/approach: In order to construct the framework, the paper first presents an overview of current applications of mass customization in the realm of architecture, with focus on successful models in North America. Second, the authors analyze the housing market in the UAE, focusing on challenges and opportunities. This leads to structuring the proposed advanced configuration system based on ideas of technology transfer from other industries. Finally, the profile matching model emerges as a logical consequence of the proposed advanced configuration model. Findings: The analysis of the UAE real estate market reveals interesting growth that encourages application of cutting-edge technologies not just in construction methods, but also in new modes of integrating homebuyers in a participatory dialogue for a sustainable outcome. Within the study, the authors call for new roles, digital design and information management technologies can play to enable participatory design. Additionally, the authors propose a new business model that requires extensive studies of the market, and buyers/developers behavior. Research limitations/implications: The framework proposed in this paper is considered generic and flexible. It raises various issues regarding its applicability, specifically with regard to market readiness. One of the first challenges is possibility of gathering precise data about the housing market in UAE to measure its size and readiness. Additionally, there are also challenges in finding focused developers and builders that are ready to engage in a dialog toward adopting mass customization as a business model. Practical implications: Mass customization implies adopting a flexible, technology-oriented business model. This raises multiple implications: developing configuration systems, the number of design alternatives has to be limited to three or four options in order to avoid additional overhead cost; implementing a digital platform for customization requires investment in tools, systems, and accordingly operators. Higher cost associated with mass customization occur both in sales and customer interaction as well as in manufacturing; and conducting a financial framework for implementing the proposed system requires intensive market studies which is considered challenging. Originality/value: The proposed framework derives its novelty by analyzing mass customization theories, technological enablers, various research endeavors in housing, and currently adopted online marketing and sales strategies in the UAE housing market. The implementation of the proposed system would represent a mile stone in the UAE housing market, being capable of redefining the process through which homebuyers, architect, and housing and developers communicate.

Harnessing, distributing, tempering and supplying water, heat and power in a building produces its share of design, technical and coordination issues. Specifically, the relationship between hygiene and cooking functions and architecture has been underscored by even the most ancient civilizations as these services give a building its potential to serve and showcase architecture's hospitality. The relationship between services and architectural space has long challenged designers and manufacturers to streamline their piecing together. Throughout construction history and modern architecture in particular the wet service core or utility core sought to organize an efficient way of zoning services, their production and construction integration; The utility core epitomized this rationalization within a self-contained engine-like device positioned to serve the entire dwelling. This paper proposes an extensive review of literature and practical exploration in order to detect new potentials for designing integrated, technology-driven, flexible and adaptable prefabricated utility cores for today's industry. The core was intended as a hub accommodating mechanical and technological equipment; electrical services, plumbing fixtures, water supply, drain, waste, vent piping, telephone cables, and easy connections to site infrastructure. Today's techniques and building information modeling allows the core to be redefined in relation to multiple scales and various organizational possibilities with regard to space/function connections. Further an adaptable core articulated to the «open building» theoretical framework of layering systems to avoid entanglement and to maximize durability, can be part of a comprehensive strategy to enable customization. The vast amount of literature and precedents contribute to a robust historic narrative of two distinct approaches of architectural rhetoric and industrial production. This paper will endeavor to illustrate this narrative and evaluate the potentials for achieving broader application.
