In the beginning, trailer travel was primarily recreational, as vacationers realized that it was a fun, budget-friendly way to tour the country. When the Depression hit, however, families who had lost jobs and homes packed their lives into these crowded campers. Though originally never intended as full-time dwellings, manufacturers identified this as a new trend.

The trailer home rose to the occasion during WWII as emergency housing on military bases and employee lodging near factories engaged in war production. With hundreds of manufacturers dispersed throughout the country, portable trailers were conveniently and quickly wheeled to locations, and over time, average square footage increased and livability improved.

By the 50s and 60s, trailers were viable domiciles and mobile home ‘parks’ had sprouted up along the outskirts of thousands of towns. A typical park had a central shower and laundry facility with outhouses placed between every two units. The mobile home offered modest, affordable housing for young and old alike in all regions of the country.

6.1 Living in a manufactured home park or community

Today's mobile/manufactured home delivers all the amenities and comforts found in a “site built” home, but at 20 to 35% less cost per square foot. Today's manufactured homes are constructed with materials virtually identical to those used in traditional site-built homes. Economies of scale and the efficiency of factory production produce savings that are passed on directly to the home buyer.

Manufactured home communities offer an easy lifestyle that leaves you more time to do the things you really want to do. Enjoy carefree living with the independence of home ownership.

6.2 The affordability factor

The affordability of manufactured housing is mainly attributable to the efficiencies of the factory process. The controlled environment and assembly-line techniques remove many of the problems of the site-built sector, such as poor weather, theft, vandalism and damage to building products and materials stored on site. Also, factory employees are trained, scheduled and managed by one employer, as opposed to the system of contracted labor in the site-built sector.

Manufactured home producers also benefit from the economies of scale which result from being able to purchase large quantities of building materials and products. As a result they are able to negotiate the lowest possible price for items that are invariably more expensive in a site-built house.

6.3 Financial benefits of living in a manufactured home community

Many people don't understand the financial benefits that can be realized from leasing land while owning their own home. When you live in a manufactured home park or community, you purchase your home but lease the land where your home is located. When home buyers make their housing purchase with land costs included, their total housing costs increase significantly. When purchasing your home but leasing the land upon which your home is sited, your initial dollar investment is much lower.

This lower initial investment puts more money in your budget each month to save, cover living expenses, or give you some of the extras you want and need. If you invest your savings, the earnings could offset the rent you pay on your home site, further reducing your monthly expenses.


7.1 Prefabricated housing 16th-17thcentury

The history of prefab houses starts with Britain global colonization efforts, in 16-17thcentury settlements in today’s India, Middle East, Africa, New Zealand, Canada and USA required rapid building initiatives. Since British were not familiar with many of the materials in abundance in the various locations worldwide. The earliest cases recorded was in 1624,where houses were prepared in England and sent to fishing village of the cape Anne in what is known today as Massachusetts and in 1700s and early 1800s was time for Australian settlements by England.

It was reported that the earliest settlement in New South Wales was home to prefabricated hospital. Storehouses and cottages that were shipped to Sydney arriving in 1790.thesw simple shelters were timber framed and had timber panel roofs, floors and walls.

Another interesting building was the prefabricated hospital that the British Army deployed in 1855 during theCrimean Wardesigned byIsambard Kingdom Brunelwith innovations in sanitation, ventilation and a flushing toilet.

In the United States, Prefabricated homes were produced during theGold Rush, when kits were produced to enable Californian prospectors to quickly construct accommodation. Homes were available in kit form by mail order in the United States in 1908.

7.2 Prefabricated housing during 1900s

Before the Industrial Revolution, prefabricated housing was unheard of and nearly impossible. However, as machinery became more and more sophisticated, so did the items that assembly lines were able to produce and homes became one of those items.

Everything from a vacation cottage to a multi-family residence could be ordered, delivered and set up, all without leaving home. From the simplest family residence to a veritable mansion, nearly any type of home imaginable could be ordered through Sears & Roebuck.

Prefab during Second World War

The factory built homes has been a dream about to come since the end of Second World War.Prefabricated housing was populardue to the need for mass accommodation for military personnel. 'Prefabs' were built after the war as a means of quickly and cheaply providing quality housing as a replacement for the housing destroyed during the war.

Prefab spread out in America depression

During Depression-era, Americans were more than ever concerned with affordable housing. Prefabricated home design gained interest throughout the country, both through mail-order catalogs and other outlets.

Designs of prefab houses also began to expand. New materials were used, such as glass in the Keck Crystal house, and steel and iron in the Stran-Steel Houses.

The metal prefab became most recognizable in the Quonset hut, which, developed during World War II for quick housing needs, did more to damage the reputation of the prefab house than to further it

7.3 Modern Prefab homes

Today, many architects and designers have revitalized the prefabricated home, designing products that incorporate the best features of prefabrication and the individuality of traditionally built homes. Available in a variety of building materials, styles and price points, modern prefabricated homes build on the rich history of their predecessors.

“If you can’t find it designit”-----is the long standing motto of Massimo and Leila Vignelli, those iconic designers of everything from plastic to melamine plates to the New York subways map. That was the same reason which made prefab architects to make research from one generation to another to bring homes which are affordable enduring health and now more than ever environmentally sound.

Kaufmann is part of new generation architects, who are modernizing prefabricated houses. They are taking the old idea of prefabrication and reshapingit to accommodate modern lifestyles and varying climates as well as commitment to the environment.

Even the small changes we make in our daily lives, as well as large decisions we make about the kinds of homes we want to live in can create transformation that will benefit for generation to come. - Kaufmann (Architect)

Prefabricated homes are improving like other forms of buildings and the main advantage of a prefabricated home is the potential to reduce the harmful impact on our environment. This is one of the world’s biggest concerns these days.



Modular homes are homes that are created in sections, and then transported to the home site for construction and installation into finished home. All of the material from framing, roofing and plumbing to cabinetry interior finish and electrical are identical to what you would find in conversional site built homes. Modular home is typically installed and treated like a regular house, for financing, appraisal and construction purposes, and are usually the most expensive of the three. Although the sections of the house are prefabricated, the sections, or modules, are put together at the construction much like a typical home.


Manufactured homes, known also as mobile homes. In the past manufactured homes were considered similar to themodular homes and that they are made of boxes; this similarity accounts for much of the mistaken impression thatthe twoproducts are identical. The fact that both two types of home aremanufacturedin a factory also confuses people. The difference between manufactured home and modular home is quiet substantial. Manufactured homes are built only to preemptive federal codes governed bya given country while manufactured homes, along with stick, pre cut and panelized homes are always built in compliance of state or local building codes. Mobile homes are homes built on wheels that are able to be moved from place to place. Mobile homes and manufactured homes can be placed in mobile home parks, and manufactured homes can also be placed on private land, providing the land is appropriately zoned for manufactured homes.


Panelized homes are constructed out of factory-built wall panels that are typically 8 feet tall and 4 feet to 40 feet long. Some paneling systems include plumbing wiringand insulation already installed; while othersinclude only framing and external sheathing (open panel system) panel system is assembled into a homeby using crane to set them into a foundation


Precut homes are assembled out of the same basic sticks as conversional homes except that thecorrect pieces are pre-selected and cut to size at a factory. Of the four systems ofbuilding, Precut kits provide the least factory assistance to the builders, since the factory does not assembleany of the building material.
