BUILDING BYELAWS
A bye-law is a local law framed by a sub
ordinate authority viz. Municipal corporation,
Town planning department or revenue authorities
on construction & planning of different types of
buildings.
Every city has its own building byelaws for
safety margins, height, floor area ratio, water
supply, drainage & structural design etc.
The above mention authorities sanction the
building plans after scrutinizing them as per the
byelaws.

BUILDING BYELAWS
It is available in form of booklets at office of
concerned authorities.
The regulation set out the basic requirements to be
observed in the of design and construction of
buildings. They are applied to new building and also to
extensions, material alterations, and certain changes of
use of existing buildings.
It is defined as the standards and specification
designed to grant minimum safe guard to the workers
during the construction; to the health and comfort of the
users and to provide enough safety to the public in
general.

ORIENTATION OF A BUILDING
Cross Ventilation
Damp proof course
Placing of walls
Projections
Roof
Treatment of ground
Wind direction

Orientation
Directly connected to the standards of thermal comfort and ventilation.
Guided by natural elements viz. (sunlight and its intensity, direction of the
wind, seasons of the year and temperature variations).
Maximum solar radiation in winter and minimum in summer.

Cross - Ventilation
Cross ventilation is obtained by having windows in both sides of
the room, causing airflow across the space.
Positive pressure on the windward and/or a vacuum on the
leeward side of the building causes air movement across the room
from the windward to the lee side, provided the windows on both
sides of the room are open.

Damp Proof Course
Damp proofing is a type of waterproofing applied to building and
foundation walls to prevent moisture from passing through the
walls into interior spaces.
A DPC is usually a thick plastic strip bedded into the mortar
between two courses of bricks or blocks. It can often be seen as a
thin plastic line in the mortar near ground level.

Placing of Walls
Walls should be placed according to planning and proper orientation of a
building.
It depends of various factors of principles of planning of a building.

Projections
Projections are provided on external wall openings to get protections from
rain, snow and heat.
Roof
• It can be defined as a structure which is
enclosing the space and offers protection from
natural factors viz. rain, snow, heat, wind etc.

Principles
of
Planning
(cont.)
 ECONOMY: building should have min floor area
with
max utility
 It should not achieved at the cost of strength Only with proper planning and utility
of
maximized (passage being
minimized)
 Can be achieved by,
 Simple elevation
 Dispensing of porches, balconies,
lobbies
 Reducing storey height
 Reducing no of steps of stairs
spac

being
 Standardization of sizes of various
components
