Barrier Free Environment is one which enables people with
disabilities ,old people , small children to move about safely and
freely and to use the facilities within the built environment.
 A space or a set of services that can be accessed by all, without

3. NEED OF BARRIER FREE
ENVIORNMENT
Barriers make an environment unsafe and cause a high level of
difficulty to the user. But more importantly, barriers cause spaces to
be out of reach, denying people the opportunity of participation in
various spheres of life.
The goal of barrier free design is to provide an environment that
supports the independent functioning of differently able individuals
so that they can get to, and participate without assistance, in every
day activities such as procurement of goods and services,
community living, employment, and leisure.

 Convenient Place for Seats of
disabled peoples is near the
entrance and exit.
 Mostly seats provided at front rows
or back rows.
 But why the peoples with disability
should always seat at front and
back rows.
 So design of seating space should
be considered in the middle rows.
 Level of seats should be increased
to improve sightline.
 Passage for person with wheelchair
should be 1.0m (min)

 Another option instead of ramp
design is Wheelchair Stair lift.
 No need of ramp design , less
space required.
 Railing on one side is required.
 Can be used on the wall side.
 It is also a good option for ramp in
auditorium.
Option 4-Wheelchair stair lift
