Architects & Designers

All disabled people have the right to access the physical environment, transportation, information, and communications on an equal basis with others. This page centers disabled people’s expertise to help architects and designers create genuinely inclusive spaces that go beyond minimum code compliance.

Why This Matters

The built environment shapes who can participate in society. Stairs exclude wheelchair users. Poor lighting excludes people with low vision. Overwhelming sensory environments exclude many autistic people. Bad acoustics exclude deaf and hard of hearing people.

These barriers aren’t natural—they’re designed in. And what’s designed in can be designed out.

Code compliance is the floor, not the ceiling. ADA minimums were negotiated compromises from the 1990s. Universal design aims higher: environments that work for everyone without requiring adaptation or specialized design.

Universal Design as Philosophy

Beyond Compliance

The US Access Board establishes minimums. ADA compliance is the “absolute bare minimum”—a starting point, not a destination.

Common compliance-only failures:

Meeting technical requirements while ignoring usability
Meeting scoping provisions (how many accessible elements) while making those elements hard to find
Creating “accessible” features that look institutional and stigmatizing
Focusing only on wheelchair users while ignoring sensory, cognitive, and neurological needs
Treating accessibility as an afterthought added late in design

The Seven Principles (Original)

Ron Mace’s original Universal Design principles:

Equitable Use: Useful and marketable to people with diverse abilities
Flexibility in Use: Accommodates wide range of preferences and abilities
Simple and Intuitive Use: Easy to understand regardless of experience
Perceptible Information: Communicates necessary information effectively
Tolerance for Error: Minimizes hazards and adverse consequences
Low Physical Effort: Can be used efficiently with minimum fatigue
Size and Space for Approach and Use: Appropriate for reach and manipulation

Updated Goals (IDEA Center)

The IDEA Center’s eight updated goals:

Body Fit: Accommodating a wide range of body sizes and abilities
Comfort: Keeping demands within desirable limits of body function
Awareness: Ensuring critical information is perceived
Understanding: Making methods of operation intuitive and clear
Wellness: Contributing to health promotion and injury prevention
Social Integration: Treating all groups with dignity and respect
Personalization: Incorporating opportunities for choice and expression
Cultural Appropriateness: Respecting and reinforcing cultural values

Design Philosophy

Universal design isn’t about making separate “accessible” features—it’s about designing so everyone can use the same elements. A curb cut isn’t an accommodation for wheelchair users; it’s good design that helps everyone including people pushing strollers, pulling luggage, or walking with canes.

Participatory Design

”Nothing About Us Without Us”

Research and design done with disabled people, not for them. Users become co-designers, and lived experience constitutes expertise.

Design based on assumptions about what disabled people need often fails. Design based on genuine collaboration produces spaces that actually work.

Implementation

Include disabled people on design teams—not as consultants brought in at the end, but as integral team members from project start.

User testing with diverse disabled people at multiple stages, not just final review.

Compensate participants for their expertise. This is professional work.

Provide accommodations so disabled people can actually participate—accessible meeting spaces, interpreters, materials in alternative formats, flexible schedules.

Avoiding Tokenism

Don’t rely solely on fictional user personas
Don’t have one disabled person represent all disabilities
Give disabled participants actual decision-making power, not just advisory roles
Address accessibility barriers to participation itself

Models

Gallaudet University’s DeafSpace exemplifies this approach—design principles developed through close observation of how deaf people actually use space, formalizing the assets of a population rather than starting from deficits.

Institute for Human Centered Design maintains a database of “user/experts” covering physical, sensory, cognitive, and neurological disabilities across age ranges.

Sensory-Friendly Design

Why It Matters

For many autistic people and others with sensory processing differences, standard built environments are overwhelming. Fluorescent lighting causes headaches and difficulty concentrating. HVAC noise makes conversation impossible. Bright colors and busy patterns create visual chaos.

Sensory-friendly design creates spaces that work for neurological diversity—not by being bland, but by being intentional about sensory input.

Lighting

Avoid fluorescent lighting. Flickering (even imperceptible flicker) and harsh color temperature affect many people.

Use flexible LED lighting with adjustable color temperature and intensity.

Manage natural light to reduce glare and harsh shadows. Provide blinds or shading.

Avoid strong light-dark contrasts that can be disorienting.

Design lighting for user control where possible—not just one switch for an entire space.

Acoustics

Acoustics are often the most important factor for autism-friendly environments. Good acoustic design starts with building layout:

Consider adjacencies. Don’t put quiet spaces next to mechanical rooms or high-activity areas.

Graduate transitions between quiet and loud spaces rather than jarring changes.

Use sound-dampening materials on walls, floors, and ceilings.

Address HVAC noise at the design stage, not as an afterthought.

Reduce reverberation in large spaces. Hard surfaces bouncing sound create overwhelming environments.

Color and Visual Environment

Muted, neutral, pastel tones work best for many—blues, greens, light purples.

Avoid bright saturated colors including stark white, which can be harsh.

Minimize strong patterns on walls and floors. Busy visual environments create cognitive load.

Consider contrast for wayfinding while avoiding overwhelming visual complexity.

Spatial Strategies

Include nooks, niches, and private seating for territorial control.

Create escape spaces/withdrawal rooms where people can go when overstimulated.

Design sensory transition zones between environments with different sensory characteristics.

Use clear, predictable layouts that reduce cognitive load and support navigation.

The UK Standard

BSI PAS 6463 (2022) provides the first standard specifically for neurodiversity and the built environment, covering lighting, acoustics, décor, and layouts. It’s an excellent resource for designers new to this area.

Wayfinding for Cognitive Accessibility

Multi-Sensory Approaches

Effective wayfinding works across sensory modalities:

Visual: High-contrast colors, large sans-serif fonts, pictograms, consistent design language.

Tactile: Raised text and braille, textured pathways, tactile maps.

Auditory: Announcements, audio beacons, sound cues at decision points.

Redundancy: Provide the same information through multiple senses so people can use what works for them.

Signage Best Practices

Simple, clear language (avoid jargon)
Universal pictograms (ISO 7001) alongside text
Consistent design throughout the building
Logical positioning 3-5 feet before intersections (time to process before reaching the decision point)
Mixed-case text (not ALL CAPS, which is harder to read)
Multiple viewing heights for different mobility device users
Good contrast (light on dark or dark on light)
Non-reflective surfaces

Landmarks and Organization

Create distinctive landmarks at key decision points
Use logical spatial organization that matches expected mental models
Maintain clear sightlines where possible
Avoid identical-looking corridors and spaces

Technology Integration

Indoor wayfinding apps for smartphones
Bluetooth beacons triggering spoken directions at decision points
QR codes linking to accessible information
Interactive directories with accessibility features

Accessible Spaces by Type

Healthcare Facilities

Examination rooms with accessible equipment (tables lowering to 17-19 inches, wheelchair scales)
Clear wayfinding with multiple modalities
Sensory-friendly waiting areas (or alternatives to crowded waiting rooms)
Privacy for communication access (interpreters, AAC)
Accessible routes including emergency egress

Educational Facilities

Classrooms designed for Universal Design for Learning (flexible seating, good acoustics, adjustable lighting)
Quiet study spaces and sensory break rooms
Accessible laboratories, maker spaces, and studios
Performance and athletic spaces with accessible seating, participation options, and routes
Emergency egress from all instructional spaces

Accessible meeting rooms with hearing loops and space for interpreters
Accessible break rooms and restrooms
Clear wayfinding throughout

Retail with clear aisles, accessible checkout, and manageable sensory environments
Transit hubs with multi-sensory wayfinding, accessible platforms, and real-time accessible information

Housing

See Housing Section for detailed guidance, including:

Adaptable design (easily modifiable as needs change)
Accessible design (fully accessible from construction)
Smart home features for independence

Emergency Egress

Requirements

At least two accessible means of egress are required from any accessible portion of a space. “Accessible means of egress” must be usable by people with mobility disabilities, not just ambulatory individuals.

Areas of Refuge

When exit stairs are the only means of egress, areas of refuge provide protected waiting areas. Requirements include:

Fire-rated construction (stairwells, elevator lobbies with standby power)
Wheelchair space (30” x 48” minimum per person, with space for multiple users)
Two-way communication systems connecting to a constantly attended location
Signage with International Symbol of Accessibility and tactile characters
Instructions visible

Evacuation Devices

Stair evacuation devices help evacuate wheelchair users down stairs. Important considerations:

Moving wheelchairs down stairs is risky and should be done by trained personnel
Always ask the person how they prefer to be evacuated
Practice evacuation procedures, including with disabled building occupants
Some people cannot be safely evacuated via stairwell devices (very heavy power chairs, certain disabilities)
Evacuation chairs and sleds have different advantages for different situations

Accessible Notification

Emergency notification must be accessible:

Visual alarms (strobes) in addition to auditory alarms
Vibrating notification devices where appropriate
Accessible public address systems
Visual emergency information displays
Multi-language and plain-language warnings

Personal Emergency Evacuation Plans

For buildings with employees or regular occupants with disabilities, individual evacuation plans identify:

Best evacuation routes for each individual
What assistance is needed
Who provides assistance (including backups)
Where to shelter in place if evacuation isn’t possible
How to communicate during emergencies

Affordable Accessible Design

The Cost Myth

Accessibility doesn’t have to be expensive. Many features cost little or nothing when designed in from the start:

Lever-style door handles vs. knobs
Motion-sensor lighting
Non-slip flooring
Contrast for wayfinding
Wide doorways (minimal cost difference in new construction)
Blocking for future grab bar installation

The expense comes from retrofitting—which is why designing accessibly from the start makes economic sense.

Budget-Conscious Approaches

Prioritize elements with greatest impact
Use standard products (lever handles, contrast paint) rather than specialized equipment
Design adaptability so changes are easy later
Phase implementation if necessary
Consider lifetime costs, not just construction costs

Smart Home Technology

Consumer smart home products can provide accessibility features affordably:

Voice-controlled lights, locks, and thermostats
Video doorbells
Automated blinds
Remote monitoring and alerts
Programmable routines

Working with Clients

Advocating for Accessibility

When clients push back on accessibility:

Frame as investment, not cost. Accessible buildings serve more people, age better, and avoid retrofit costs.

Highlight legal requirements. Explain that ADA applies to places of public accommodation and that accessibility lawsuits are common.

Emphasize demographic trends. The population is aging; accessible design today serves tomorrow’s users.

Show examples. Well-designed accessibility doesn’t look institutional. Share images of beautiful accessible spaces.

Quantify the market. People with disabilities and their families represent significant purchasing power.

When Compliance Isn’t Enough

Sometimes clients want to exceed minimums. Support this by:

Bringing Universal Design expertise
Connecting with disabled user/experts for design input
Researching best practices beyond code
Documenting the accessibility features achieved

Documentation

Document accessibility features for:

Building operations and maintenance
Future tenants and occupants
Accessibility marketing
Demonstrating compliance if questioned

Key Principles Summary

Compliance is the floor, not the ceiling. Design beyond code minimums.
Design with, not for. Include disabled people as co-designers throughout the process.
Consider all disabilities. Mobility, sensory, cognitive, and neurological—not just wheelchair users.
Integrate, don’t segregate. Accessible features should be part of the main design, not separate add-ons.
Redundancy is essential. Provide information and access through multiple modalities.
Design affects dignity. Accessible features shouldn’t look clinical or stigmatizing.
Design for change. Adaptable design allows modification as needs evolve.
Universal Design benefits everyone. Curb cuts help parents with strollers; good acoustics help everyone concentrate.
