Steps of planning
• Collect information about the proposed building like purpose and
general scope of its component.
• For example if the proposed building ios to be used for residential
purpose, commercial purpose, industrial purpose, public use etc.
• Select a suitable site or plan of the building according to the site
available.
• Place the plan elements with proper correlation giving consideration
to the levels, aspect, prospect, orientation, convinence, comfort and
attention to other principles.
• Adopt proper proportions and shape of units of building from
practical utility and aesthetic point of view.

Any special/Specific
requirements?
• Basement parking

Plan
• A projection of the portion of
horizontal plane when the
building is imagined to be cut
by a horizontal plane slightly
above the window sill level is
plan.

Preparing the architectural drawings:
• Site plan

 Plans
 Sections
 Elevations

Bubble diagram

Rough Sketches…. !
India

Line plan / Line Diagram
• First prepare a line plan for the
residence so that the changes
needed can be easily done.
• A line plan is a plan which
doesn't take the wall thickness
into account.
• While preparing a line plan the
orientation on plot, north
direction, direction of prevailing
winds, location of roads etc.
Should be taken in account.
India
11

Preparing sketch plan
• Sketch plan is prepared from
the lie plan after the wall
thickness, position of doors
and windows, columns and
beams, direction of openings
etc.
• It is the final plan taken into
consideration.
India
12

Wall thickness
oFor R.C.C. Structures we use
• 230 mm – external walls
• 150 mm – internal walls
oWall thickness of 150 mm including plaster on both sides or 200
mm excluding plaster is more preferred than 230 mm thick wall
including plaster.
oFor load bearing structures 200 mm to 300 mm thickness walls
are used.
India
13

Openings
• For residential buildings the doors open
inside and the door, window and
ventilator frames must be kept in flush
inside the wall.
• The opening for doors must be
carefully planned such that the doors
don’t block the passage or that it
doesn’t partially or fully block opening
for other doors or windows.
• Complete specifications for door,
windows and ventilation should be
given.
India
14

Dimensions
• Dimensions should be clearly
visible and be positioned such
that they are within the
boundaries of room and are not
crowded.
• They should not be placed such
that they go unnoticed.
• Overall dimensions of the four
sides of the buildings should be
mentioned and the should tally
with the sum of dimensions of
the room in series along the
direction.
India
15

Miscellaneous
• Draw kitchen otta, sink, built in cupboard, W.C. Pan,wash basin,
staircase, front and rear steps.
• Verandah column should not obsturct the full view of the main
entrance door or the window of drawing room.
• Projections from walls as sunshades, porches and beams from
verandah column which are above sill level windows are to be shown
in dotted lines.
• Scale for plan should be written as 1 cm = 1 metre but not as 1 m =
1 cm. i.e. Fraction should be greater than 1.
• Conventions and symbols for stone masonry and brick masonry,
wood and concrete work etc. should be done after dimensioning and
indicating names in lighter shade compared to main drawing.
India
16

What is section?
• Section is a full view of
building in vertical plane
from foundation level to
top of parapet wall.
• It reveals all details of
construction.
India
18

Elements
• All construction details from foundation to roof are to be shown
i.e.
• Thickness of wall
• Foundation for the walls
• Slab thickness
• Flooring details for finish and bed below flooring
• Vertical heights above the floor top
• Height of doors and windows
• Lintel thickness
• Sunshade projection and thickness
India
20

Section line
• Section line should be broken
line having one long dash and
twos short dashes alternately
and evenly spaced.
• It should pass through doors,
windows, cupboard, bath
room, W.C. And stairs,
showing all the interior
details.
India
21

Heights
• Heights from floor level to foundation bed level and floor level to
top of roof should be shown.
• Vertical dimensions for study objects like window, chajja, door
etc. Which are cut by section line and project those in wall.
• Height of room in case of R.C.C. Slab roof is measured from
floor level to the bottom of roof slab and that in 1st class and 2nd
class mud roofing is measure from floor level.
India
22

WHAT IS ELEVATION?
• Elevation is the appearance of
the building above ground level
in vertical plane.
• Elevation is one of the most
important architectural aspect of
a building giving an overview of
the appearance of the building
after construction.
• Dimensions in elevation are to
avoided completely if possible.
India
24

Standard dimensions for
various building units

Standard Dimensions for Various
Building Units
• The minimum depth of foundation is kept 1m below the ground
level.
• Plinth height may be kept 500mm to 600mm but 450mm is
more common.with greater plinth height,the building gets
majestic appearance.
• Plinth area should be a minimum of 1.2 times the floor area of
the building.
• Minimum width of footing = 2t + 2j
Where,
t = thickness of wall immediately above basement level (not <200 mm)
j=offset of concrete(not <100 mm)
India
26

Building Units
• Thickness of the damp proof course is 20mm to 25mm.
• Floor finish is generally with 10mm to 20mm thick cement mortar or
tiles.
• Ceiling height for main rooms of a residential building should be
3000mm to 3600mm.
• The carpet area should be 50% to 65% of the floor area.
• Main entrance door of a residential building should be of 1000mm *
2100 mm in size. other doors should have a minimum width of
900mm and height of 2000mm.
• Doors for W.C. and bathrooms are 600mm to 750mm* 1800mm with
single leaf shutter.
India
27

Building Units
• The size of window depends on the total area of window
openings required. therefore following things should be kept in
mind.
1. Window width=1/8(width of room + height of room)
2. Glass area in windows should be 10% to 20% of floor area of the room
for good lighting.
3. At least one sq.m. of window area should be provided for every 30 cubic
metres of inside room space. Generally the minimum size of window is
750mm*1000mm.
4. Window sill level is 900 to 1200mm above floor level.

Stairs:
• Rise in residential building = 130mm to 190mm.
• Rise in office building = 125mm to 150mm.
• Tread = 275mm to 350mm for public building.
• Tread = 250mm to 300mm for residential buildings.
• Thumb Rule:
(T + (2*R) ) = 550 to 650 (mm)
(T * R) = 39000 to 48000 (s.q. mm)
• No. of risers = (Total height of floor)/(Height of riser)
• No. of treads = No. of risers - 1
India

Building Units
• Thickness of R.C.C. lintel beam is 100mm to 250mm and150mm is more
common.
• Thickness of R.C.C. roof slab is 100mm to 150mm and that of sunshades is
25mm to 50mm.
• Sunshades project through 450mm or 500mm beyond the facing of external
walls.
• Width of verandah is from 1.8m to 3m and width of passage is 0.8m to 1.2m in
residential houses.
• The height of parapet wall should not be less than 0.60m and not more than 1.2
m above the finished floor level.
• The minimum size of ventilator is 1000mm*500mm in order to provide good
ventilation for any habitable room.
India

Special Requirements for low
income housing:
• Maximum plinth area = 40 sq. Meter
• Plot Size = 30 s.q. meter to 200 s.q.metre
• Maximum height of building = 15 m
