ABSTRACT
A HOUSING SYSTEM: A STUDY BASED ON THE PRODUCTION CAPABILITIES
OF THE MOBILE HOME INDUSTRY
By Duane A. Kell
Craig E. Rafferty
Submitted to the Department of Architecture on May 26, 1972 in partial fulfillment
of the requirements for the degree of Master of Architecture, Advanced Studies.
This thesis is intended to develop within the mobile home industry an increased
responsiveness to user needs through an understanding of the elements necessary
for improved design quality within a living unit.
The written section provides a brief overview of the mobile home industry, establishes areas of concern, long range potentials, and the constraints within
which the design proposal is made.
The design proposal demonstrates how modular coordination of basic living elements
and a simple expansion technology can generate many combinations called modules.
Using eighteen sample modules and varying exterior components, the proposal
illustrates the many unit variations possible, and demonstrates new site planning
concepts generated by these units.

INTRODUCTION
The housing industry is composed of three sections: the traditional building industry, the manufactured building industry, and the mobile home industry. They
differ primarily in their organizational structures and their production techniques.
They are similar in their end product, a dwelling unit. Of the total number of
new dwelling units produced each year, the mobile home industry produces roughly
half. Clearly it is the mobile home industry that has the largest impact on the
housing market.
The underlying reasons for this success as a producer of housing are briefly as
follows:
- Cost performance and production efficiency
- Managerial structure, organization as industrial process
- Procurement capabilities, bulk purchasing, etc.
- Efficiency in use of time and materials, factory control, repetition, etc.
- Uniform performance code (nationally accepted)
- Distribution networks, producer - distributor - dealer - consumer
- Political structure and lobbying strength
The industry has a product that has grown out of a need for low cost single-family
dwellings in a nation that is confronting an increasing housing crisis and continuing
inflation.
Unfortunately, the stigma associated with thoughts of "low cost and low
income" has affected broad public acceptance.
This low public acceptance level
9
reflects itself in public policy towards taxation, building codes, zoning, and highway regulations that limit further growth of the industry.
Zoning, for example, usually places the mobile home in undesirable and isolated
areas that are far removed from urban problems and that produce sub-optimum sociological conditions. This, in turn, simply serves to lower the public acceptance level.
It seems obvious that improved public acceptance and creation of an image of the
mobile home asa viable living alternative is needed.
Of the many steps necessary
to achieve a higher level of public acceptance, improved design quality is one of
the first.
It is the area dealt with in this thesis.
10
AREAS OF CONCERN AND DESIGN CONSTRAINTS
There are three overriding areas that are important in evaluating the implications
of improved design quality. They are: the factors that affect user needs; the
factors that affect quality; and, the factors that affect visual aesthetics. Analysis
of all of the factors such as circulation, mechanical systems, size of spaces, natural
light, etc., must generate a design that concentrates on establishing relationships
between the exterior of the mobile home and its surroundings, the functional interior of the mobile home and a variety of user needs, and the interior and exterior
spatially.
These areas of concern are inherently in conflict with highway regulations that
limit weight, height, length and width. Weight is a minor factor due to lightweight construction, 13'-6" has remained constant as the maximum height, and
lengths over 70' require excorts in most states.
Regulations that originally limited
width to 8' were changed to 10' in the 1950's, 12' in the 1960's, and the 1970's
will see national acceptance of 14'.
Despite any of the constraints the mobile home industry is working under, one must
think realistically of its potential as a tremendous national resource for housing due
to its excellent technological, managerial, and political skills.
The industry is presently recognizing the inherent conflict between the limitations
of transportation and the need for larger living areas.
Its attempts have incorporated
elements that pull, fold, and telescope as well as units that are made in sections or
can split into sections at the site.
11
Further speculation on the long range potentials of the mobile home industry need not
be limited to the mobile home per se, but to a full range of housing types, densities,
and site situations ranging from the single family detached to the multi-story, multifamily attached.
In view of the extensive range available, the following basic constraints have been
established to facilitate the design study and to yield a basis for comparison.
UNIT TYPE
Individually shipped manufactured units that incorporate minimum volumes
of shipped air and maximum use of existing technology
UNIT SIZE
a. 14'-0" maximum shipping width
b. 56'-70', minimum to maximum shipping lengths
c. 13'-6" maximum shipped height
UNIT CONSTRUCTION
a. Standard mobile home steel framing
b. Standard mobile home wood framing
c. Standard mobile home expansion technology
UNIT ERECTION
Two or three men, two days using standard erection procedures (excluding
foundations which can vary in sophistication).
Efficient use of these givens yields a system of organization that produces a maximum
number of plan variations with a minimum number of assembly line changes.
