Disabled-Friendly Design Principles

The Fundamental Principles of Accessible Architectural Design

1. Equal Use:
   • Providing the same products and environments for all users.
   • The understanding that individuals with disabilities have equal rights, not privileges.
2. Flexibility in Use:
   • Offering options that cater to different needs and preferences.
   • Allowing the same product or environment to be used in various ways.
3. Simple and Intuitive Use:
   • Designs that are not complex and are easy to understand and learn.
   • Enabling users to operate products without needing prior knowledge.
4. Perceivable Information:
   • Design that targets different senses so that individuals with visual, auditory, or other sensory impairments can access information.
   • The use of visual, auditory, and tactile signals.
5. Tolerance for Error:
   • Minimizing the consequences of accidental errors.
   • Having feedback mechanisms that allow users to learn from their mistakes.
6. Low Physical Effort Requirement:
   • Products and environments that can be used with minimal physical effort.
   • Designs that can be easily used by the elderly, children, and those with limited physical strength.
7. Appropriate Size and Space for Approach and Use:
   • Designs with dimensions and layouts that suit users' body sizes and movements.
   • Spaces where individuals with disabilities can move comfortably using wheelchairs or walking aids.

The Importance and Benefits of Accessible Architectural Design

• Quality of Life: It enables individuals with disabilities to live independently and participate in society.
• Accessibility: It creates a society where everyone has equal rights and discrimination is eliminated.
• Economic Benefit: Accessible designs can be more economically viable by catering to a broader range of users.
• Social Awareness: It raises society's sensitivity towards individuals with disabilities.

Application Areas of Accessible Architectural Design

• Buildings: All types of structures including residences, schools, hospitals, government buildings, and shopping centers.
• Outdoor Spaces: Public areas such as parks, gardens, sidewalks, and parking lots.
• Transportation: Public transit facilities like bus stops, metro stations, and train stations.
• Products: Items such as doors, restrooms, stairs, elevators, and lighting systems.

Features of Accessible Architectural Design

• Ramps: Ramps with adequate incline and width for wheelchair users.
• Elevators: Elevators that are sufficiently spacious and easy to use.
• Tunnels and Bridges: Tunnels and bridges that are adequately wide and well-lit.
• Restrooms: Accessible restrooms that are available and appropriately sized.
• Doors: Automatic or easy-to-open doors.
• Sensory Signage: Tactile signs for the visually impaired and audible alerts for the hearing impaired.
• Lighting: Adequate and appropriate lighting.
• Contrast: Sufficient contrast in floors and walls to help visually impaired individuals orient themselves.

Considerations in Accessible Architectural Design

• Starting from the Planning Phase: Incorporating accessible design principles from the beginning of the project.
• Compliance with Standards: Adhering to national and international accessibility design standards.
• User Participation: Involving individuals with disabilities in the design process by soliciting their feedback.
• Regular Inspection and Maintenance: Regularly inspecting and maintaining buildings and equipment.
