Conventional Construction
“…the only way that the all important future can be divined is with reference to our memories of the past – there is nothing else.” The evolution of building materials and techniques has shaped the way structures are constructed today, one key aspect of the evolution of construction methods is the progression of building materials.
a – Historical Development
Traditional construction methods have deep historical roots, it can be traced back thousands of years to ancient civilizations such as the Egyptians, Greeks, Romans, and various indigenous cultures. These early societies developed techniques for constructing shelter and infrastructure using locally available materials like stone, clay, wood, and thatch. These methods were often influenced by environmental factors, cultural practices, and the available knowledge of the time.
Initially, people used natural materials, and over time, they discovered how to refine and process these materials for enhanced structural integrity.
For example, the Romans developed concrete, which revolutionized construction by allowing for the creation of larger and more durable structures. “…lime, which, until the mid-nineteenth century, was the only cement available for use in masonry mortar, plaster, and concrete. Today, the use of lime is limited to modest quantities in mortar, stucco, whitewash, and soil stabilization.” As societies advanced, so did their knowledge of materials, leading to innovations such as steel, reinforced concrete, and advanced timber treatments.
Alongside material innovations, construction techniques evolved to accommodate larger and more complex structures. Innovations like arches, domes, and buttresses allowed for the construction of grand architectural wonders, like the Colosseum and the Pantheon in ancient Rome. Similarly, advancements in engineering and construction methods enabled the construction of skyscrapers, bridges, and other modern projects.
The historical roots of traditional construction methods continue to shape modern construction practices. While modern construction has incorporated cutting-edge technologies and materials, it still relies on foundational principles derived from traditional methods. For example, load-bearing principles, structural stability, and architectural aesthetics all draw from the knowledge and experience gained over centuries. Traditional construction methods often emphasized sustainability by using local materials and environmentally friendly practices, “sustainable building design and construction is not a new concept. It is an idea that reemerged in the 1970s and gathered momentum after the 1973 oil embargo. At that time, the focus was limited to energy conservation and the use of alternative energy sources in buildings.” . In today’s world, there is a resurgence of interest in these traditional practices as societies seek more sustainable and eco-friendly building approaches.
In conclusion, the history of construction methods is a testament to human ingenuity and adaptability, they are also preserved and celebrated for their cultural and historical significance. Traditional construction methods, rooted in ancient civilizations, laid the foundation for the development of modern construction practices.
The following provides an analysis of key characteristics, advantages, and disadvantages of conventional construction related to interior spaces.

Modular and Prefabricated Construction
Modular and prefabricated construction are innovative building methods that have gained popularity in recent years due to their efficiency, sustainability, and cost-effectiveness. These approaches offer a departure from the traditional on-site construction by involving the manufacturing and assembly of building components in controlled factory settings. “The Modular building Institute defines prefabrication as the process of manufacturing and assembling the major components of a building at a remote offsite location, while the subsequent installation is carried out at the construction site” These modules are typically self-contained, complete with walls, floors, ceilings, electrical, plumbing, and even interior finishes. Once manufactured, they are transported to the construction site and assembled like building blocks to create the final structure.
On the other hand, prefabricated construction involves the manufacturing of building components, such as walls, roof trusses, and floor systems, in a factory or off-site facility. These prefabricated components are then transported to the construction site, where they are assembled into the final building. “A building can be classified as belonging to the prefabrication of the component if the prefabrication portion is more than 50% of the total building value, and the differentiation is made by determining the value or proportion of the prefabrication and the components manufactured on site.”
Both modular and prefabricated construction methods offer solutions to address challenges in the construction industry, such as labor shortages, construction waste, and project delays. They are particularly valuable in projects where time and cost efficiency are critical, and they can be applied to various building types, including residential, commercial, healthcare, and educational structures, to name a few. As technology continues to advance and the construction industry evolves, modular and prefabricated construction are likely to play increasingly prominent roles in shaping the future of building construction.

By the mid-19th century, prefabricated iron and steel components found application in the construction of bridges, railway stations, and various infrastructure projects. “Mass production of motor cars led to similar concepts for housing, starting firstly with panel or component-based systems and later extending to modular or volumetric units” . This approach not only expedited construction timelines but also mitigated labor costs.
The emergence of kit homes in the late 19th and early 20th centuries, notably by companies like Sears, Roebuck and Company in the United States, further advanced the realm of prefabrication. “The concept of the kit house likely originated in the U.K., but after these mail-order residences were introduced to the U.S. market in the late 19th century, they became synonymous with the American dream.” These homes, marketed through catalogs, came complete with pre-cut lumber and other essential building materials, allowing customers to undertake assembly themselves or employ local contractors for the task. World War II played a significant role in accelerating the development of prefabricated structures, including military barracks, hospitals, and housing units. During Post-war, the experience with prefabrication had a lasting impact on the construction of affordable housing, particularly in Europe.
The mid-20th century ushered in further innovations in modular construction, with companies such as the Lustron Corporation in the United States producing entire houses in factories, featuring built-in appliances and fixtures. The 1960s and 1970s saw the commercial sector embrace modular construction, employing modular components in the construction of office buildings and schools. In the contemporary landscape, modular construction has undergone a significant evolution. It finds widespread use across various sectors, offering high levels of customization, energy efficiency, and sustainability.

Casa SIP, Chile, Architects Alejandro Soffia & Gabriel Rudolphy, (2009)
Casa SIP, a remarkable 139 square meter residence nestled in Santo Domingo, Valparaiso, Chile, designed by Alejandro Soffia and Gabriel Rudolphy. “Following a long research (since 2002) on prefabrication in low cost housing and self customization, we decided to step aside in designing new components and create a constructive system from low developed components available in the construction market. So we took “structural insulated panel” (SIP) catalogue and read its simple topology to define minimum spatial modules which multiplied and related could build, in this case, a house.” This project is predominantly constructed of modules, each thoughtfully crafted into 6-square-meter that were seamlessly joined together to give shape to the final product.
a – Exterior
The exterior of the home, is a post-assembly panels, “The panels are configured in a staggered arrangement to create a two storey building made up of volumes of different dimensions that match their functions.” and “The wall panels measuring 122x244x11 and slab panels at 122x488x21, with a total of 71 wall panels and 40 slab panels meticulously assembled.” . It was adorned with a rain screen made of wood slats, and it is worthy to note that this is a Zero-Waste Home in Chile. Strategically oriented along a north-south axis, Casa SIP’s modules are multiplied along this trajectory. The west-facing facade presents a more open view of the ocean, in contrast, the east side is thoughtfully designed to offer enhanced privacy, creating a cozy sanctuary. The ground floor roof is transformed into a deck, providing an ideal point for observing the ocean. What truly distinguishes this architectural project is the remarkable speed of construction, with the entire home taking merely 10 days to be realized. This efficiency is a testament to the advantages of the prefabricated and modular design, which not only accelerated the construction process but also minimized waste and debris, leaving behind virtually zero environmental footprint. Casa SIP stands as an exceptional example of sustainable and efficient architecture, blending form and function into an exquisite living space.
b – Interior
The SIP house stands as a testament to thoughtful architectural design, boasting a three-story structure. Within its confines, a harmonious amalgamation of spaces, drawing upon traditional programmatic affinities to establish a cohesive whole. Key to this design is a central circulation axis, around which the various functional spaces elegantly converge. “Through the configuration of spatial modules comprised of two wall panels and two split-level panels, inhabitable spaces measuring 6 square meters were built. These spaces are the result of multiplying these volumes along the length of their transversal axis according to standard surfaces of use. The house is comprised of the sum of these different spaces.”
Upon entering the SIP house, the primary areas, carefully clustered towards the northern facade, gift inhabitants a panoramic view of the neighboring sea. This orientation not only frames the natural beauty beyond but also maximizes natural light intake, creating a welcoming and vibrant interior.
However, the exceptional quality of this architectural configuration transcends its internal spatial characteristics. The outer-facing horizontal surfaces situated on the second and third storeys function as versatile terraces. These exposed regions, adorned with sophisticated and contemporary design components, beckon a diverse range of recreational and leisurely activities. These terraces provide a dynamic expansion of the habitation area, perfectly merging the indoor and outdoor environments.
The SIP residence stands as a testament to the efficacy of astute architectural strategizing, merging conventional and contemporary elements to produce a habitat that not only captivates visual perception but also enhances the human spirit. It seamlessly integrates the breathtaking seascape with utilitarian design, transforming every moment spent within its confines into a cherished experience.

“The project proposes the idea that every modular apartment can be expanded, renovated or replaced accordingly to demographic changes. The building is integrated with the landscape, allows for open views, maximizes day lighting and natural ventilation; and creates emotional spaces. Smart built-in and loose furniture provide a high level of functionality and flexibility in term of use and materiality. Rather than a completely fixed building, we try to create a flexible architecture which can breathe, grow, and tell an open-ended story of life.” The units are designed to maximize space utilization, providing comfortable living areas despite their compact size, sliding panels are used to separate the functions and help adjusting the space according to the family needs. On the Other hand, the Communal areas are strategically placed to encourage interaction among residents while minimizing wasted space. Cost-effective materials and finishes are employed to maintain affordability. The housing complex is designed with energy-efficient features, such as insulation and energy-efficient appliances, reducing long-term operational costs and environmental impact.
In conclusion, The Nest Modular Housing project reflects a forward-thinking approach to address the evolving needs of the local population in an ever-changing economy. This innovative housing development, constructed with modular method of construction, embodies adaptability, sustainability, affordability, and a strong sense of community. It is a testament to the potential of adaptable, and affordable housing solutions that can cater to the changing needs of urban populations while fostering a sense of community and environmental responsibility. This development serves as a model for future urban housing projects in the cities around the world.

Conclusion
In conclusion, this research has undertaken a comprehensive examination of the implications of modular and prefabricated construction methods on interior architecture and functionality, drawing comparisons with conventional construction approaches. The history of both methods of construction was introduced, and the key characteristics, advantages and disadvantages of both methods were examined. The study of the two examples, Hive-Inn, Hotel, Frankfurt and Casa SIP, Chile, and the analysis of the case study, The Nest, shows that the adoption of modular and prefabricated techniques in the construction and interior architecture fields, brings forth a countless of benefits, such as heightened precision, stringent quality control, and expedited project completion. The interior spaces, within these projects, are designed for functionality, simplicity, and adaptability. Smart, standardized modules and efficient use of space cater to the needs of the target demographic. The Nest project shows the flexible architecture of the units that allows for expansion, renovation, or replacement as demographic changes occur. Communal areas encourage interaction among residents, and cost-effective materials and finishes maintain affordability. Energy-efficient features contribute to long-term cost savings and a reduced environmental footprint.
These methods also contribute to cost-effective construction, reduced on-site waste, and the potential for sustainability advantages. However, it’s crucial to acknowledge that design flexibility can be somewhat constrained, particularly in intricate or highly customized projects, while transportation and on-site assembly logistics may pose initial cost disparities when compared to conventional construction. A comparison was made in a table prepared by the researcher that concludes the findings. The true significance of the findings, within this paper, lies in their potential to initiate a profound transformation within both the construction and interior architecture sectors. For the construction industry, modular and prefabricated methods offer a promising avenue for increased efficiency, reduced construction-related risks, and enhanced cost predictability. This could potentially lead to the expansion of the modular construction sector, necessitating adaptations in workforce skills and project management approaches.
For the interior architecture industry, these findings open up new horizons. Interior architects can leverage the advantages of modular construction to broaden their design horizons and portfolios. This necessitates heightened collaboration and communication between architects, builders, and interior architects, underlining their growing importance in modular projects. Furthermore, there is a growing demand for sustainable interior architecture solutions that align with environmental concerns.
While this study has provided valuable insights, numerous unexplored avenues await further research, these include methods for enhancing design flexibility within modular and prefabricated construction while maintaining efficiency; an assessment of user satisfaction in modular and prefabricated buildings compared to traditionally constructed spaces; a long-term cost-benefit analysis to determine the justifiability of initial cost differences over a building’s lifecycle; and an exploration of emerging technologies and innovations in modular construction that have the potential to further enrich interior architecture possibilities.
Future research in these areas holds the promise of deepening the comprehension of the evolving relationship between modular and prefabricated construction and interior architecture functionality. It will also serve as a valuable resource for industry professionals and stakeholders, helping to place this topic in context within the broader academic and professional landscape.
A query for future researchers to ponder: What will be the ongoing impact of the dynamic relationship between modular and prefabricated construction methods and interior architecture on the constructed environment, and how will it influence the processes of design, and construction?
