Introduction According to the Habitat Agenda, “in many countries, particularly developing
countries, more than half the existing housing stock has been built by the owner-
occupiers themselves, serving mainly the lower-income population. »1
Indeed self-construction is the more direct answer to the basic need of shelter one
would build up because it cannot be solved in any other way. Self-construction
concept can at first be seen as a necessity. It is a primary form of architecture to
which people turns to with very limited means.
Are there not important aspects to be considered in the way people settle as it is
done spontaneously, in a building process learning from direct experiences of the
context in which the house is settled? And how, from a shelter professional’s
point of view, architects should interpret and consider self-construction?
Because nowadays, in a developing country context, self-construction is broadly
done in a very independent way, with poor means, sometimes in illegal
circumstances, on dangerous sites, this way of settling is threatened but also
threatens somehow its inhabitants. And the main answer to self construction’s
limits has been to erase its realization and provide many, fast built and cheap
housing units, all identical, too often un-adapted, and thus left empty.
What can be done to adapt a spontaneous way of settling to today’s issues, to
improve poor people’s living conditions? Could some guidelines be defined,
useful for residents and professionals, able to facilitate and organize self-
construction sustainability?
The Rich Lecture of Self-construction’s Architecture Foreword The starting point of this investigation is the observations made in a European
context that when people take part in the design, or construction process of their 1 UN Habitat The Habitat Agenda Goals, Principles, Commitments and the Global Plan of Action.

day to day environment (the house itself but even its surroundings), they are very
often much more able than building professionals to meet their own needs and
desires.
There is in these circumstances a part of appropriation and participation that, to
me, is necessary to generate “good built environments”.
Considering self-construction in a developing country context is rather different,
but still the lecture of the resulting architecture is an open book of clues as to learn
how people use, or need the space to be. In this perspective, self-construction
presents an undeniable reason to be studied carefully.
Just from looking at this picture of an informal self construction on Smokey
Mountain in Manila, Philippines, different categories of information can be got:
Ways of Using the Space – Defining Building Types The way people use the space is understandable from the building choreography.
From the picture above it is rather difficult to assume the uses of the space done
by its users. Plans and sections can make this apprehension more explicit as it has
been done in the experience lead by SADEL and ASDEAR in Tunisia.
Where before starting a program of organized self help housing, these
organizations have made observations and studies to understand better the existing

framework. They learned that courtyard was a omnipresent polyvalent space in
each house people built by themselves, the rooms of the houses were rather long
and narrow, and that they were used only for sleeping as kitchen was improvised
outside.
This choreography of buildings’ shape is very much influence by the uses and
habits of their users, culture and beliefs, social and gender organization as well.
Building Materials and Construction Devices Used The materials used in self-construction process are the one found around the place
where the house is built. These resources vary from a rural context to an urban
one. Where the picture above has been taken, on a mountain made of garbage,
mostly left over pieces of plastic, wood, metal, cardboard are used as well as any
piece of industrialized furniture as the piece of mattress used as façade material.
In the countryside for instance in the Philippines a self settler would rather use
available bamboo or stones like in the northern, mountain areas.
These materials will influence the way the houses are built, but they are also
adequate to the place they are used in the sense that they are local.
Climatic or environmental issues also very often influence the way they are then
implemented. As we can see on the picture, the house has been elevated, because
there are risks of sliding soil, especially during the rainy season.
Reading self construction gives many informations as to know the materials
available on the site and the devices used to implement them.
Expression of Needs What can already be read from the above picture is that this family needs more
space: to store (basket hanging from the wall), or a place to dry the washed
clothes, from a general view the house tends to extend on each side to the outside.
The expression of the needs of the users from the space configuration starts to
show the limits it has achieved and that should be taken into consideration.
If there are too much goods in a room, there is a need of storage, if the cooking is
made outside, it’s wether because of the smell, or because there is no space inside
where the pretented kitchen is used for something else, it is also because the
climate allows cooking to be done outside.

Indeed a deeper look to a spontaneous shelter can give many clues about the needs
of its inhabitants, especially from what you can see the house is not able to
provide an answer. Limits show needs, a need satisfied is no longer a need.
Hindrances to Decent Living Conditions The Habitat Agenda includes this general definition to what should guarantee a
Shelter: “Support progress and security for people and communities, whereby
every member of society is enabled to satisfy his or her basic human needs and to
realize his or her personal dignity, safety, creativity and life aspirations ».
The first limit of self-construction is reached as soon as the house threatens these
basic needs. The reasons why they fail in that are not only financial or material
(because we can see many housing project with expensive materials and devices
enable to achieve them), the problem is mainly in terms of lack of technical
assistance and means, but also because of a lack of awareness and support from
the authorities to start with.
Even if the qualities and assets of self construction have to be considered, as
nowdays there is a go back to the roots and a carefull attention brought on
vernacular architecture for its adapted feature to the place the building is located,
spontaneous architecture should also be considered as a proper architecture. But
obviously its limits have to be underline and that’s where architects and building,
social professionals have to work on improving it, step by step, hand by hand with
its architect, the resident themselves.
Organized Self-help Construction as an Answer to the limits of Self-construction2
The concept of organized self-help housing is rather recent (100 years) and means
that there is a facilitating organization that both assists the households that have

chosen this program, and that bears a responsibility to authorities and financial
agencies.
« To support the efforts of people, individually or collectively, to produce
shelter » the Habitat Agenda strongly advices governments to facilitate
community-based production of housing, through promoting it, new policies,
integrating and regularizing existing self constructions, and through facilitating
access to housing resources (such as land, finance, infrastructures, buildings
materials).
A Human Perspective The starting point of a self-help project is the participation of the families taking
part in it. Their needs and resources are what is going to define and shape the
design of their houses. Studies, surveys, interviews and many observations are, of
the many tools the facilitating organization can use to better understand people’s
experiences and needs. Self-help programs’ slogan sound as facilitating an
architecture for people by people.
Cost Efficiency It is the most famous advantage of self-help housing programs. Indeed people’s
participation in the working process (partly of fully) enables to considerably lower
the cost compare to similar produced houses by contractors within the formal
sector, as you can see on the board bellow.

The way the project is organized is key to keep the self-help project competitive,
as well as the amount of time the families can spend on working, together with the
capacity and efficiency of the facilitating organization. We can also strongly
believe that in a long-term view, the cost of maintenance will be reduced as the
residents have learnt how to repair and run the houses.
Common Participation What it also brings out, as a new asset from self-settlement process is that
developing a project in community makes the development of a neighborhood
sustainable and lively. The teamwork allows to learn about the future
neighborhood but also to discover the potentials of sharing work in community.
But here again, as the cost efficiency, generating an identity and feeling of
community is a fragile construction. It depends also on the way the program is
organized and the timelines, when a self help housing project is late, families
loose energy and thus money, which will brings out less motivation..
The facilitating organization has to play a constant part in sharing with the
families, bringing support and advises.
Proposal for Guidelines As we can guess from the description of the self help housing process, it is a
whole organization that needs to be adapted to each project, families’ situation
and resources available by the last ones and the site.
But still, there are general advices architects and residents could refer to, as to
achieve sustainable and fair self-construction in an organized process.
Enable the Families to Contribute to their own Development The families need to be involved, in many ways of participating, in different
phases of the project so that after that the facilitating organization leave the work,
the families are not lost in their own home. For that also, they should be aware of
any decision to be taken in the process and have the last word.

Consider the Existing as the Starting Point As we have seen, the existing pattern before support is provided to the families is
rich of information to consider. It’s not because spontaneous, or self-construction
is fragile that it should be ignored or erased. If you look at the many projects done
by many architects whose challenges are only to design many, fast to build and
cheap housing units, they do not solve the housing crisis for low-income
households. They are even bringing in new problems because their design is not
able to consider many other parameters than are part of the quality of living as
much as having a toilet box… What happens generally if the project are not
adapted to people uses and needs, they won’t stay in, which generate important
loss of money…
Clear Objectives, Timetable and Responsibilities To stay competitive, a self help project has to follow a realistic and strategic
pattern that clearly defines who has to do what, and this has to be agreed between
all the families and the actors involved.
Provide Permanent Support, Advice and Training The facilitating organization should encourage and accompany the families
through the different phases of the project by providing the mental energy
necessary but also training and training about construction devices and technics.
Numbers of self-help programs in construction have shown that the residents were
refinding self confidence and proud through their work.
Research in Alternatives A self-help project has something experimental and in that sense it should go
further in researching for financial alternative means to make it possible for each
family to shelter oneself. The research in alternatives should also look for
affordable, easy to implement but also environmentally friendly construction. This
challenge should be in the objectives of the project since the beginning, we
couldn’t make anymore the economy of this issue.it should not be anymore taken
away issue.
