The document outlines guidelines for designing and constructing barrier-free buildings to accommodate individuals with disabilities, emphasizing the importance of accessibility in public and private spaces. It addresses specific architectural features, such as the dimensions of doorways, the need for ramps, and the layout of facilities to ensure safe and comfortable access for wheelchair users and others with mobility challenges. Overall, the aim is to create inclusive environments that enable equal participation in society for people with disabilities.

2. • one billion persoOomic and attitudinal barriers that exclude participation as equal members of socie
 Over one billion people with disability face physical, social,
economic and attitudinal barriers that exclude them to
participate as equal to other members of society.
 People with disabilities lack equal access to basic resources,
such as education, employment, healthcare, social and legal
support systems.
 Disability in poor countries has remained invisible in the
mainstream development agenda.
 Besides lack of awareness, understanding of accessibility and
accommodations remain an obstacle to the achievement of
progress.
Dr. Y. P. Gupta, Consultant, Allahabad

3.  In physical terms, the problems of disabled children are much the
same the world over. But while problems may coincide, the ways by
which they ought to be resolved may differ.
 Appropriate solutions are governed by the way that services are
organized, along with social, economic and cultural influences.
 For architects, there may be some circumstances where similar
design solutions will be proper and others where they will not be.
 The houses, schools and other public places need to be designed to
cater for children in wheel chairs & walking aid.
Dr. Y. P. Gupta, Consultant, Allahabad

4. • Design for disability includes:
• Mobility
• Vision
• Hearing
• Speech
• Cognitive
• Within the public and private sectors

5. 1. Layout of the home should be clear
2. Oblique walls should be avoided as they give a
wrong direction impression
3. Big areas should preferably have a clear
conceptual layout, like a rectangular or square
area
4. Pillars, etc. should not be of same color as
background
5. Living room, toilet/shower, and bed-space should
be on ground floor in 2 story buildings or more.
Dr. Y. P. Gupta, Consultant, Allahabad

6. 6. Bedroom should preferably be next to a bathroom.
7. When there are indented areas, the straight,
imagined continuation of the wall should be free
for walking.
8. Walking can be supported by clear contrast of the
floor material to the surrounding walls

8.  An adaptable home is one which is built or renovated to allow
low cost and easy adaptation to the changing needs of the
residents.
 For disabled people and elderly, this means that devices
assisting the activities of daily living can easily be installed.
 A prerequisite in order to achieve the benefits of a smart home
is a barrier-free physical environment that supports the
residents.

avoided as it can cause injury to the hands of children with problems of co-
ordination
 Compared with normal children, handicapped children may spend more of their
time at or near floor level.
 Therefore: Floor finishes must not be very smooth like smooth marble
 Floor finishes should be comfortable to walk, play on, easily cleaned and pleasant
to touch.
 Handrails should be fixed to walls only along main circulation routes; they ought
not to be fixed indiscriminately
 Some protection may be needed to wall surfaces in particular locations but the
general provision of buffer rails is not recommended.*

in and around the facility to apply design for disabilities. The
following are some examples:
– Parking Lots
– Entrances and Exits
– Travel Routes
– Public Restrooms
– Restaurants
– Emergency Notifications

43.  Accessible doors should be so designed as to permit
operation by one person in a single motion with little
effort.
 Power-operated doors are the best for children with
disabilities
 The activator system should be automatic or placed
within easy reach
 An accessible door should have the following features: a
sign, a door handle, an extra pull handle, glazing and a
kick plate.
 Rooms designated for wheelchair children should, where
possible, be placed at ground level so as to have a direct
means of escape in case of fire

46. Dr. Y. P. Gupta, Consultant, Allahabad
In addition ramps it should have kerb so as to
avoid accidents because of slipping

47. Dr. Y. P. Gupta, Consultant, Allahabad

48.  For parking facilities of less than 50 cars, at
least one accessible parking space should be
provided in every parking facility.
 For outdoor parking, accessible parking
spaces should be located not more than 50 m
from accessible building entrances.

49. Parking Places:
 For indoor parking, accessible parking spaces should be
located right next to accessible elevators, or as close as
possible to exits.
 The ends of rows are preferable for vans with lifts for
wheelchair users.
Dimensions:
 The minimum width of an accessible parking space is 3.60
m. The recommended width is 3.90 m as shown.
 An access aisle 1.20 m wide can be located between two
ordinary parking spaces.
 For indoor parking, the minimum height clearance for vans
with hydraulic lifts is 2.40 m.

51. • Passageways serving accessible areas must not be less than 1-
200 wide, preferred minimum 1-600
• Where lobbies are incorporated between doors, there must be
space for wheelchair maneuvers
Circulation areas
• Vertical circulation between floors must be by means of a
lift. At entrance level the floor of the lift must be at the same
level as the entrance door

Accessible Area

54.  Curb ramps are used wherever there is a difference in level on
pedestrian paths or cross paths.
 To avoid confusing sightless pedestrians, curb ramps should
be positioned out of the usual line of
pedestrian flow. The unobstructed width of the pathway
should be not less than 0.90 m .
 Curb ramps should be located away from places where water
accumulates.
 Standard curb ramps: Cut back into the pavement with flared
sides providing

55.  In public buildings, the function or room number,
incorporating international symbols should be
identified at eye level, i.e. between 1.40 m and 1.60 m.
 Room numbers should be placed on door frames and not on
doors themselves so that the room number is visible even
when the door is open.
Colour:
 The door or the door frame can be painted in a colour that
contrasts with the adjoining wall to facilitate its identification
by people with visual impairments.

56. *
Travel Routes
•Objects that protrude into the hallways must be
avoided.
•Sketch below shows a blind person identifying
objects in a hallway.

57. *
Automotive Mobility - Lifts
• Platform Lift - requires either two side doors, or one sliding
door on a van and is stored either on the side, the rear or
under the floor of the van.
• Rotary (Swing) Lift - beneficial because of the parking
conveniences, due to less room needed to enter and to exit
the van. This device swings into the van, and the lift
platform sits on the floor in the middle of the van.
• Trunk Lift - puts the scooter into the trunk, provided the
scooter measures less than the trunk.
• Under-the-Floor Lift - only pump and motor are located
inside.

58. *
Automotive Mobility
Door Openers:
• Chain Door Opener - slide door that travels in a track located at the top of the
van.
• Pivot Arm and Push/Pull Gear Door Opener - used to open
double-outdoors outward.
Parking Brake Extensions:
• Electric Parking Brake - motorized and can be set and released by a switch
located within easy reach of the driver. This is ideal for those with limited foot
and leg strength. The use of electric parking brakes have been used for
customers without disabilities as a upgrade to the manual parking brake and
also for weight reduction..
• Manual Parking Brake - for those with limited foot and leg strength. It is a
handle attached to the parking brake and is long enough to operate by hand.

59. *
Social and Emotional
Considerations
An assistive device may make a person stand out
more than a conventional device, causing the user to:
-Look Different
-Become Embarrassed
-Become Self Conscious
-Do that particular activity less

60. *
Social and Emotional
Considerations
Although a device may
improve an activity for
someone, if it leads to the
person doing the activity less it
may be leading to more harm
than good.

61. In this way if we provide some of these basic aids in the
homes for our disabled children who are our very own but not so
fortunate children, at least we can try
make their lives more independent, emotionally stronger,
little more enjoyable & develop more confidence in themselves
& build up more confidence
