In the past two hundred years, the world has undergone rapid, drastic changes that have altered how we live.  With the Industrial Revolution came a focus on the factory rather than the human being.  This meant that the living conditions of the workers fell far below previous standards, forcing up to twenty people to live in a single room (Mumford 21).  Unsafe living conditions only continued with the continual growth of cities throughout the twentieth century.  The question that architects must consider is how do we address these growing populations?

In One Hundred Years of Humanitarian Design, Kate Stohr discusses the importance of architects’ involvement in disaster relief and redevelopment projects.  The question of whether architects should be involved in the processes at all seems to be one with a simple answer.  Yes.  If we can help others, why not?  It is a matter of finding the correct method and design strategy for each location and situation.  Each and every area in need of new or improved housing is unique, and there will most likely not be a single solution to such an immense and wide-reaching problem.  However, there are a few factors that seem to create positive, lasting results no matter what the situation.  Community involvement has proven to be one of the most effective tools when redesigning or redeveloping areas.  For example, in Puerto Rico in 1949, a “government resettlement and land redistribution plan…[was started, in which] families were free to design and build their own homes using any method that made sense” (Stohr 43-44).  This gave them the ability to create their own houses without being forced into accepting a design that does not relate to the context or their specific needs.

In contrast with community involvement is prefabricated design, something that in the post

World War II era was one of the most useful tools that planners throughout the world had at their disposal.  With both the influx of veterans returning from war as well as the massive amount of destruction throughout Europe and Japan, prefabricated, often Modernist structures were a logical building type to move away from the old, pre-war state of mind, and into a new era.  Levittowns

sprouted up all over the world, from Long Island, NY to Iran, Venezuela, Nigeria, France, and Israel (Stohr 46).  Pre fabricated housing such as Levittowns have not proved as useful for disaster relief situations, because often, even if the structure is a simple tent, it may not arrive on site early enough to make an immediate impact, nor will it provide much more than an extremely temporary solution to a permanent problem.

An additional necessity for a successful future for a project is ownership.  When squatters do not own their homes, they often lose the desire to rebuild or revitalize the existing structure since they live in constant fear of losing what they have.

This was addressed in PREVI, in Lima, Peru, because the new residents owned the homes and were encouraged to add to them as time and money allowed.  In fact, it was part of the project brief itself that the structures be easily added to.  This meant that they were invested in the future of their homes, and were free to make them into anything they wanted to.  The ability to adapt each home to the occupants specific needs creates a dynamic city with a variety of aesthetics that are each uniquely personal.  In this way, despite the standardized designs that each architect involved in PREVI created, each block no longer appears monotonous, but rather incredibly active, each house with its own character.

With the rise of NGO’s and aid organizations, architects have no excuse not to help those in need of well designed, sustainable homes.  We have the knowledge and skills to improve the living conditions of the immense percentage of our planet that currently lives in slums, yet somehow nothing is done about it.  Stohr’s article proves that between architects’ knowledge of building systems and planning, and the input of those in need of housing, relief and renewal projects can most certainly be successful.

Speed has always been a powerful word in the construction industry. It has paved the way for new technology, both low and high tech, cheap and expensive, low and high quality. Speed has also been key in shaping post disaster, post war, and rapidly developing areas. Prefabrication, historically has been the answer to these three great problems. That said, the innovative technology that many masterminds have come up with rarely sticks with prefabrication, unfortunately due mostly to cost.

The speed in construction came from a necessity to solve a problem. These problems throughout the ages have been as  varied as the solutions. The article 100 Years of Humanitarian Design catalogs the many prefabricated housing designs which made a mark on history. What it doesn’t catalog however is what can be called the final chapter, the slum dwelling. It is the culmination of all the different types prefabricated houses; including both good and bad qualities. As a lead up to this cumulative prefabricated housing typology, a background of its predecessors is in store.

To begin, an earthquake in the early 1900’s destroyed much of San Francisco. The answer to the housing lose problem was to supply its population with small prefabricated rentable wooden cottages. Worried about permanent squatters in the city’s parks, San Francisco set up a system where renters of the cottages would become owners if they moved them from the city’s parks onto a permanent lot. Several years later 5,343 of the original 5,610 had been relocated; solving multiple problems in one foul swoop.

Another example of prefabricated housing is the Sears house. These houses were available starting in 1908 and ending in 1940 and sold nearly 100,000 homes. These houses could be put up in about 90 days with around 30,000 parts delivered by train car. These models shined in both ease of constructability and quality of the end product. In addition these houses cost only a fraction of the average early to mid century home.

The last example of prefabricated house that will be covered was developed by futurist Buckminster Fuller called the Dymaxion House. Rethinking the conventional house which made “no structural advances in 5,000 years” Fuller designed a house which made efficient use of both materials and structure.This house although seemingly unrelated to the slums of today has one thing in common. The fact that it requires next to no maintenance (the outside of the Dymaxion House is clad in aluminum).

The slums of the world should be categorized as prefabrication in its most crude sense. As a way of further understanding this notion, consider what prefabrication means to the building; cheap, readily available materials, and easy to construct. This aligns almost directly with the dynamic assembly of a slum.

First, Most, if not all slum building materials are found materials; plywood, cinder-blocks, corrugated metal for example, making them both cheap and easy to obtain near and around slums. In addition, the construction of slums is done by the squatters  themselves, obviously this dictates them very easy to construct. To reiterate, the common slum dwelling is in essence the next chapter in cheap, disposable, movable, pseudo temporary housing, akin to a double wide trailer. The most important thing to note is that each and every new version of temporary housing typology was designed to solve a problem.
