Mass Production for Mass Housing

For everyone, their home is their palace, and they are the kings and queens of their own little palaces. But if we start making palaces for everyone, we will only be building castles in the air. The urgent need of the hour is to build more houses, with fewer resources, in the quickest time, for the many seeking a pucca house.

We will need to create a paradigm shift in the way we design, engineer and construct social housing in India. If we continue to construct our houses and apartment buildings like we have being doing since the past three decades, it will be impossible to reach our intended target anytime in the foreseeable future.

There can be much learned product design and manufacture, including car manufacture. Some of the key aspects that can be directly transferred to house construction are:
  • Modularity: Modularity is a design approach that sub-divides a system into smaller components that can be replicated, scaled, and used in groups or independently. Modularity helps in reducing costs and has been extensively in car manufacture, computer manufacture, etc. Even in the furniture industry, the concept of modularity has been widely accepted as modular office furniture and modular kitchens.
  • Standardization: Modularity can be truly successful only through standardization. Standardization implements uniform technical standards and norms across the industry. This assures, uniformity, quality and ease of repetition.
  • Mass production: Mass production is the process of manufacturing large quantities of standardized products. This frequently utilizes assembly line technology. Mass production is the process of creating large numbers of similar products efficiently. With pre-cast/ pre-fab technology mass production in the construction industry has become a reality.

The concept of “Design for Manufacture Assembly (DFMA)” is gaining popularity in the design and construction industry internationally. The idea combines the two design approaches – “Design for Manufacture” and “Design for Assembly”. The idea is to treat the building as a “kit-of-parts” to be manufactured and assembled on site. It requires a paradigm shift in the way architects and engineers design buildings.

Though pre-cast technology exists, its applicability is immensely limited. Only when mass production is combined with modularity and standardization can pre-cast/ pre-fab have an industry-wide applicability and use, and be truly effective. Mass production has been highly successful in the car manufacturing industry and computer industry because of modularity and standardization.

Another argument against mass production of houses is the lack of uniqueness in buildings and monotony of urban landscape. But, don’t we all own cars that are mass produced and standardized to a great extent? Do we ever complain? Of course, different car manufacturers and different models look different from each other, but we have thousands of each brand and each model on the roads. There is modularity, standardization and mass production behind it.

I will talk about this a bit more in my next blog.

Layermag

This is one of the few web-sites dedicated to South Asian architecture and architects. Though in it's nascent stages of development, I think it holds the potential to be the spearhead of an oncoming change. Web-sites and resources like these are quite necessary and useful to make people aware about contemporary and future movements in the South Asian region. "LAYER finds its roots in diversity. It was born out of a common desire to launch a platform for interaction, exposure and participation of South Asian designers, at all stages to experience and share their ideologies, which will help evolve the present status quo. LAYER indulges in all aspects of design and art. The nature of exhibitions, curational strategies and publications, demands new interrogation and reconsideration. This is fueled by the fact that in recent years, worlds of art, architecture and design have outgrown their modes of representation and production, and have started to cannibalize neighboring discip...

Architecture - An Impure Art, an Inexact Science

Many of you would not disagree with the statement that Architecture is combination of Art and Science. If Frank Lloyd Wright proclaimed Architecture as the “Mother of all Arts”, then why not the “Mother of all Sciences”? Why has the mother embraced one child and forsaken the other? The Oxford English dictionary defines Art as: “The expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power.” The Oxford English Dictionary defines Science as: “The intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.” Art in its pure form appeals to our sense of the ideal and our highest aspirations, experienced through passion and instinct. Whereas Science in its pure form tries to understand nature and the environment by ...

Affordable Housing in Mumbai

Affordable Housing is one of the most important issues for Mumbai's development. due to its complex and dynamic nature it is a big challenge for the Government, urban planner and all stakeholders. In Mumbai, approximately 42% of the people live in slums and about 57% households live in one-room tenements, with 9 out of 24 wards with more than 50% slum population. (Census 2011) Affordability is a relative concept. It means different things to different people. But then how do we define Affordability? A high-level Task Force on Affordable Housing for All, set up by the Government of India in 2008, and headed by Deepak Parekh, has put forth the following definition of affordable housing: (http://www.naredco.in/pdfs/report-high-level-task.pdf) For EWS/ LIG: ≤ 4 years of income or EMI/ Rent ≤ 30% of gross monthly income For MIG: ≤ 5 years income or EMI/ Rent ≤ 40% of gross monthly income Currently the two approaches being adopted to address the issue of affordable housi...
