This manual is mainly put together to help deal with working out inexpensive, effective and acceptable
housing schemes for the homeless families in Kerala.
Perhaps much of the content of the manual may be of relevance to many other parts of India.
In Kerala we have no deserts and no big black cotton soil areas, but it is hoped that some sections
of the manual will be of help to anyone planning to build small houses on small plots for homeless
families.
Some of the material may also be of help when rebuilding houses which have been destroyed by
cyclones, floods, earthquakes landslides and so on.
Almost everything in the manual has been used and tested by the writer over the past half a century
in India.
                       TRADITION VS MODERN
This is NOT meant to be a battle between traditional and modern forms of architecture.
Especially in India there is no such thing as ONE traditional INDIAN Architecture.
Every district has its own traditions and, by trial and error, over thousands of years, people have
learned how to use, and to cope with, all the many factors which are involved in Architecture. – The
Site, the Topography and Geology. The climate and vegetation, the available local materials – the
religious and cultural patterns of living, and the main local occupants.
Unsatisfactory items have long since been discarded and alternatives have been tried until a
satisfactory solution has been found.
It seems foolish, therefore, to abandon the tested findings of centuries of “Science & Technology.”
A TILE ROOF CAN ALSO BE EASILY EXTENDED – BUT YOU NEED MORE COSTLY
TIMBER FOR IT.
A CORE HOUSE
YOU MUST OF COURSE COVER YOUR GROUND FLOOR ROOMS WITH A FLAT
ROOF AND IT IS PREFERABLE, ALSO FROM THE BEGINNING, TO PLAN FOR
STAIRS.
THESE WILL MAKE YOUR FLAT ROOF UNABLE, AND OF COURSE WILL
EVENTUALLY CONNECT THE ADDITIONAL FLOORS WITH THE ORIGINAL
GROUND FLOOR.

IF YOUR PLOT AND YOUR FUNDS ARE TOO SMALL, START OFF WITH THE
GROUND FLOOR, BUT PLAN IT TO CONTAIN A STAIR TO TAKE YOU UP, FIRST
TO AN OPEN FLAT ROOF, TO AN OPEN FLAT ROOF TERRACE, AND LATER TO
ANOTHER FLOOR OF BEDROOMS ON THE FIRST FLOOR ABOVE THE ORIGINAL
GROUND FLOOR COTTAGE. THIS EXTENSION WILL ONLY COST HALF AS MUCH
AS THE FIRST BUILDING.

WHEN THERE ARE THREE BROTHERS AND THEIR FAMILIES (OR PERHAPS 3
CLOSE FRIENDS) THE THREE HOUSES CAN BE BUILT AS ONE BLOCK AND
THEN THERE IS MUCH MORE OPEN SPACE FOR EACH FAMILY.
FURTHER MORE – THE UPPER HOUSE ALSO HAS A NICE BIG TERRACE (AS
LARGE AS HIS HOUSE) ABOVE THE TWO GROUND FLOOR HOUSES.
                             COST EFFICIENCY
With the country having millions of homeless families, it is imperative that what money is available
must be used ONLY for essentials, and none of it for fancy frills!
There are many factors that must be kept in mind; MATERIALS – are the materials we want to use
for building LOCALLY AVAILABLE? If not – can we afford transport costs? Can we not use only
locally available items as far as possible?
Then we must ALWAYS keep the CLIENT in mind.
Remember that the CLIENT is the beneficiary – not a Government Department etc!
Will he be able to accommodate comfortably all his dependants?
Will he be able to extend the house when, later, his sons grow up and earn money?
Will the house be STRONG and SECURE?
Can sheds or verandas be added by him for home occupations, like carpentry or weaving etc?
Does the plan allow for local cultural and religious ways of living?
What about water and sanitation? And what about approachability?
Our aim of “Cost Efficiency” must include all these things.

SLOPING SITES
1. DON’T BUILD ON THE OUTER EDGE OF THE TERRACE. YOU WOULD NEED
TO BUILD A STRONG EXPENSIVE RETAINING WALL.
2. BUILD THE HOUSE ALONG THE MIDDLE OF THE TERRACE AND USE A LONG

                     Usually stop at floor level
                     (30 or 40 cm above ground

When soil is poor and soft – it is                                                                wall
usual to dig a wide trench and cover
the bottom with concrete. On this a
wide stone wall 50-60cm is built on
top of that.
Another use for split building BAMBOO in LIME concrete is for foundations, especially
in sandy areas along the sea coast. Salt and Saline will not affect or destroy either the
concrete or the reinforcement. (Ordinary foundations will crack with shifting sands.)

      BONDING
is the very essential art of making
BRICKS, BLOCKS & STONES

PLACE IN IT THE LARGER STONES AND THEN FILL IN, ALL ROUND, WITH

THE BOX YOU HAVE AN EXCELLENT BUILDING BLOCK.

                                         LATERITE
Laterite is found in many parts of Kerala (and in other states too). It is natural, compressed earth
and uses no energy (fuel) at all.
Unfortunately, unlike soil or sand, once ‘mined’, the quarry remains as a big hole n the ground.
It is also very heavy and lifting it up to masons working at high levels is both labour intensive and
slow, hard work.
It is however far more acceptable than cement blocks.
                              CEMENT BLOCKS
These are currently used very extensively. This is NOT acceptable when building for thousands
and millions. Cement is highly ENERGY (Fuel) INTENSIVE item and India is short of energy and
has to IMPORT much of it.
The cement used in a Block Wall is considerably more than the comparatively small amount used in
a brick wall.
Blocks are very heavy and lifting, especially above waist level – slows down construction time and
calls for more labour. Bricks are easily thrown up to any height.

                                                commonly used 9” brick wall in India.
                                                It consists of alternate rows of ‘headers’
                                                and ‘stretchers’.
The CAVITY in the RAT TRAP BOND wall ensures good insulation from
heat and cold.
This can be ruined by a poor mason carelessly slopping mortar into the
cavity while he is building.
To avoid this
1.Make sure the mortar is not too wet, and
2. Use a 3” wide strip of wood, laid over the central cavity and place the
mortar on both sided of it.
                                       BRICK JALI
‘Jali’ - formerly pierced stone panels – is one of India’s oldest methods of letting into a building
filtered light and ventilation but maintaining privacy and security.
BRICK JALI can function in the same way – either as panels or as a complete load bearing wall.
ONCE THESE PATTERNS HAVE BEEN USED – A GOOD MASON CAN DEVISE
AND ENJOY DOING MANY PATTERNS.

POINTING
Gives a smooth finish to an unplastered wall and is usually done as an extra job after the wall
construction is complete.
Much less costly is to lay the mortar, place on it the bricks, give a mild blow with your fists to the
brick and then press in the bulging mortar with your trowel.

In the orthodox reinforced concrete slab the dead weight of its concrete is heavy.
This weight can be lessened by putting light weight material between the steel rods.
The simplest ‘filler’ is to use two ______ grade Mangalore Tiles. These have no
structural strength value – they are mere ‘Fillers’.
Using them saves about 30% dead weight of the ‘slab’ – so less steel is needed – so
much steel, sand, cement metal and cost is saved.

WHENEVER THE NEED FOR HOUSING SCHEMES COMES UP, INEVITABLY
EVENTUALLY THE SUBJECT OF LATRINES SURFACES.
ALMOST INVARIABLY, FOR COMMUNITY HOUSING, SOMEONE SUGGESTS
‘GROUP LATRINES’. THIS IDEA HAS RARELY, IF EVER, BEEN SUCCESSFUL AND
THERE IS EVERY REASON WHY ALL NEW HOUSES SHOULD HAVE THEIR OWN
LATRINE.
THE OLD SEPTIC TANK SYSTEM IS STILL GOOD (IF BUILT PROPERLY) BUT IS
COMPARATIVELY VERY COSTLY. A FEW OTHER SYSTEMS AND PROBLEMS ARE
DISCUSSED NOW.
MANY FAMILIES DO NOT LIKE TO HAVE THE LATRINE UNDER THE HOUSE
ROOF. SUCH PREJUDICES CAN BE REMOVED IF THE LAVATORY IS SEALED
OFF FROM THE REST OF THE HOUSE (BOTH WALLS AND ROOF). WATER PIPING
IS ALMOST ELIMINATED WITH A BATH TAP ON ONE SIDE OF THE WALL AND A
SINK TAP ON THE OTHER.
A WIDE BUILT IN SEAT IN THE KITCHEN CAN ACT AS AN EXTRA BED AT NIGHT.

Baker’s life is a legend. He belongs to a rare species of scholars who found the roots of wisdom in common man. Laurence
Wilfred Baker was born in England in 1917. He had his education from King Edwards Grammar School, Aston. After
studying at the Birmingham School of Architecture, he became an Associate of the Royal Institute of British Architects. He
started his career as an anaesthetist to Friends Ambulance Unit, S. England during the world war and worked in China and
Burma.
As an architect to a leprosy mission, he came to India in 1945 where he was exposed to an entirely new environment. He
was fascinated to see the skills of the ordinary, poor village people working with the most unpromising and crude materials
with almost no recognizable tools to make useful everyday buildings and articles.
In 1948, Baker married Elizabeth Jacob, a like minded doctor from Kerala and settled down in remote area of the Himalayas
to run their own schools and hospitals – mixture of medical and architectural work there for more than one and a half
decade.
The land and its people enlightened his ideas and the compendium of information from ordinary people enriched his vision.
He discovered a hidden heritage in local indigenous style of architecture, the result of thousands and thousands of years of
research and collective experience of many generations on how to use only immediately available, local materials to make
structurally stable buildings that could cope with local climatic conditions, with the local geography and topography, with all
the hazards of nature, with possible hostile neighbours, houses that could accommodate all the requirements of local religious,
social and cultural patterns of living. He learnt about more and more local materials and devised new patterns using burnt
bricks, stone, mud, tiles and timber and applied new kinds of mortar and plaster in his works.
Baker abhorred all forms of extravagance and waste. Two important characteristics evolved in Baker’s architecture- the
small is not only beautiful but if often essential and even more important than large, and if architects are even to start
interacting effectively with the real building problems and the housing needs of the world, they must learn to build as
inexpensive as possible. The ideal is that there is a form of direct unity with the creator, that man experiences this at any time,
in any place and under any circumstances.
For a number of reasons, the Baker’s pulled up their roots from the Himalayas and moved to Kerala and settled in a remote
mountain area among the neglected tribal and settlers. Baker’s interest and work spread and concentrated more o housing
and rural development work. Some Industrial buildings in North and Mid-India, a lot of Churches and Cathedral were his
important contribution during this period.
By this time the Government moved in to examine what is going on. The then Chief Minister C. Achutha Menon became a
convert to his architectural style and baker built the State Institute of Languages for a small sum of money which the works
and housing department had declared was impossible. Following this a fairly large and prestigious complex known as
Centre for Development Studies and some other Government Institutions were constructed by him.
The people were quick to understand the principles involved in cost reduction and real priorities of building a house. The
upper strata came forward with interest when quite a lot of them built their houses using these simple cost reducing techniques.
For the lower middle class this style was rewarding as hey can construct a house within their reach.
As a popular specialist in the cost effective building and conservation of energy by avoiding energy intensive materials – with
a stress on updating the wonderful Indian vernacular ways and styles of building, Baker brought people close to their
culture. Through out his working life, the whole business planning and designing has been intensely absorbing and fun for
him. Always living close to nature he learned many lessons from the design of God’s creations. He has produced innumerable
designs each has a unique identity whether big or small. He breaks all conventions of shape. The free flowing lines and
graceful curves in his design create a harmonious atmosphere for living. His buildings invite the dweller to be part of it.
Planning of space in design is an important factor in cost reducing construction. In a country with 40 million homeless it is
improper to use money, natural resources or energy lavishly or unnecessarily.
As an architect of vision and vast experience Baker is ac active participant of various Government schemes. He is and has
been advisor to planning and Governing bodies of institutions like HUDCO, NID, CBRI, FRI, UPDESCO etc. and has
been active with and designed for Milk Marketing Board, Livestock Development Board. He is honorary fellow of the
Centre for Development Studies.

Baker defended critics with good humour and his sketches are excellent. He has produced do-it-yourself books, illustrated
by him titled How to Reduce building costs, Brick work, Mud, Community Buildings, Schools, Rural hospitals etc. his
writings brim with information. In all he stresses cost control and avoiding energy waste and intensive materials. He has
given two reports to Government on Earthquake.
