Accessibility Is Not a Retrofitting Exercise: It Must Begin at the Drawing Board

Across India, accessibility is still widely misunderstood as a corrective measure — something to be “added later” once a building is complete. A ramp is inserted near the entrance, a toilet is relabelled, a lift button is lowered, and the project is declared accessible. Yet anyone who has attempted to use such spaces knows that these adjustments rarely produce environments that are genuinely usable.

Accessibility cannot be retrofitted into a design that was never conceived with diverse users in mind. It must be embedded at the conceptual stage, when circulation, spatial hierarchy, services, and human interaction with the building are first imagined. When inclusion is postponed, it becomes expensive, technically compromised, and frequently symbolic rather than functional.

The Persistent Myth of Post-Construction “Fixes”

The belief that accessibility can be added later stems from two assumptions: first, that accessibility concerns only a small minority; and second, that it involves isolated physical features. Both assumptions are flawed.

Built environments are not experienced in fragments. A ramp that leads to a heavy manual door, followed by a narrow corridor, an inaccessible reception desk, and confusing wayfinding does not create access. It creates a sequence of barriers. Retrofitting often addresses one point of failure while leaving the rest of the journey intact — and exclusionary.

When accessibility is introduced after construction, designers must work against decisions already locked into the structure: plinth heights, column grids, service shafts, toilet layouts, fire exits, and level differences. At that point, meaningful change is constrained by what has already been built.

The Cost of Delay: Financial and Spatial

It is commonly believed that incorporating accessibility early increases project costs. In practice, the reverse is true.

During the design stage, inclusive planning usually involves adjustments in geometry, alignment, and specification — decisions that cost little to implement on paper. Once construction is underway, however, even minor corrections can require demolition, regrading, relocation of services, or structural alteration. What could have been achieved through thoughtful layout becomes a logistical and financial burden.

For example:

  • Designing a step-free entrance at the outset requires alignment of site levels.

  • Introducing it later may require external ramps, drainage reworking, and façade modification.

  • Planning accessible toilets from the beginning affects partition placement.

  • Attempting to enlarge them later disrupts plumbing, finishes, and circulation.

Early decisions shape the entire lifecycle cost of accessibility.

Accessibility as Spatial Logic, Not Equipment

Another reason retrofitting fails is that accessibility is treated as the installation of elements rather than the shaping of relationships between spaces.

True accessibility is about:

  • How one arrives at a building.

  • How one understands where to go.

  • How easily one can move between functions.

  • How independently one can use facilities.

  • How safely one can exit in an emergency.

These are questions of spatial logic, not accessories.

If corridors are too long without rest points, lifts are hidden, signage lacks clarity, or transitions between buildings involve level changes, no amount of later modification can fully resolve the experience. Accessibility must therefore be conceived as an organising principle — a way of structuring movement and perception.

The Indian Context: Rapid Construction, Limited Integration

India is currently witnessing an unprecedented expansion of educational campuses, healthcare institutions, transport hubs, and commercial developments. Much of this growth is driven by tight timelines and standardised construction models. Accessibility is frequently introduced only when approvals, certifications, or complaints demand it.

This reactive approach produces environments that technically satisfy requirements yet remain difficult to use in practice. Large campuses often reveal discontinuities between buildings; transport interchanges provide access at entry but not at transition points; institutional spaces treat accessibility as an isolated compliance package rather than an integrated system.

The challenge is not absence of intent, but absence of early engagement.

Why the Drawing Board Is the Most Powerful Moment

The conceptual design phase offers a unique opportunity: nothing is fixed, yet everything is possible. Decisions taken here determine whether accessibility will be seamless or forced.

At this stage, designers can:

  • Align entrances with natural pedestrian movement.

  • Establish step-free circulation networks.

  • Integrate vertical movement logically within building cores.

  • Plan sanitary facilities where they are actually needed.

  • Ensure gradients, surfaces, and transitions are inherently usable.

  • Coordinate landscape and architecture to function as one system.

When accessibility informs these foundational choices, it disappears into the design — not because it is absent, but because it is naturally accommodated.

Moving From Compliance to Usability

Compliance frameworks are necessary, but they represent minimum thresholds. Usability asks a different question: can a wide range of people actually use this environment without assistance?

A compliance-driven retrofit may achieve dimensional correctness. A usability-driven design considers human diversity — mobility, ageing, temporary injury, sensory differences, and the simple unpredictability of everyday life.

Buildings that are usable tend also to be:

  • Easier to navigate.

  • Safer in emergencies.

  • More comfortable for all occupants.

  • More adaptable over time.

Thus accessibility, when planned early, strengthens overall design quality rather than constraining it.

Institutional Projects: The Multiplier Effect

Large institutions illustrate the importance of early planning most clearly. Universities, hospitals, and public facilities function as interconnected environments rather than single buildings. If accessibility is not embedded at the planning stage, barriers multiply across distances, levels, and services.

Retrofitting one building at a time cannot resolve systemic issues such as:

  • Disconnected pedestrian routes.

  • Inconsistent level management.

  • Fragmented signage strategies.

  • Transport drop-offs that do not relate to entrances.

  • Variations in usability between old and new blocks.

Early accessibility planning allows such environments to function coherently as campuses rather than collections of structures.

The Role of Design Teams and Developers

Accessibility should not be viewed as an external audit imposed late in the project. It is most effective when design teams engage with it as part of their own decision-making process.

Developers increasingly recognise that inclusive environments:

  • Enhance long-term asset value.

  • Reduce later modification liabilities.

  • Improve public perception and usability.

  • Support demographic realities such as ageing populations.

When accessibility expertise is consulted during planning rather than after completion, it becomes a collaborative design tool rather than a corrective mechanism.

From Adjustment to Intention

Retrofitting will always remain necessary for older environments. However, new construction offers a choice: continue repeating patterns that require later correction, or shift towards intentional inclusion from the outset.

Designing access from the beginning does not require radical change. It requires a different sequence of thought — one that asks, early on, who the building is for and how it will actually be used.

When accessibility begins at the drawing board, it ceases to be a special feature. It becomes part of how architecture works.


Suggested Reading

Readers wishing to explore these ideas further may consult widely recognised guidance on inclusive design, built environment usability, and universal design approaches, including:

  • National accessibility guidelines issued for built environment planning in India.

  • Technical provisions within India’s building regulatory framework addressing access and circulation.

  • International good practice documents on usability and universal design principles.

  • Research literature examining the relationship between spatial planning and inclusive participation.

  • Studies on lifecycle cost comparisons between early integration and post-construction modification.

Prototype — Accessible to Whom? Legible to What?

When I first read this theme, I thought to myself, at last someone has asked the right two questions, though perhaps in reverse.

We often think of prototyping as a neutral, creative act—a space of optimism and experimentation. Yet, for many of us in the disability community, it is also the stage where inclusion quietly begins or silently ends.

And when Artificial Intelligence enters this space, another question arises: what does it mean for a prototype to be legible to a machine before it is accessible to a human?

My argument today is straightforward: AI-powered assistive technologies often make disabled people legible to machines, but not necessarily empowered as agents of design.

The challenge before us is to move from designing for to designing with, and ultimately to designing from disability.

Accessibility and Legibility

Accessibility, as Aimi Hamraie reminds us, is not a technical feature but a relationship—a continuous negotiation between bodies, spaces, and technologies.

It is not about adding a ramp at the end, but about asking why there was a staircase to begin with.

Legibility, on the other hand, concerns what systems can recognise, process, and render into data. Within Artificial Intelligence, what is not legible simply ceases to exist.

Now imagine a person whose speech, gait, or expression does not fit the model. The algorithm blinks and replies: “Pardon? You are not in my dataset.”

Speech-recognition tools mishear dysarthric voices; facial-recognition models misclassify disabled expressions as errors.

In such moments, accessibility collapses into machinic readability. One is included only if the code can comprehend them. The bureaucracy of bias, once paper-bound, now speaks in silicon.

The Bias Pipeline—What Goes In, Comes Out Biased

In one experiment, researchers submitted pairs of otherwise identical resumes to AI-powered screening tools. In one version, the candidate had a “Disability Leadership Award” or involvement in disability advocacy listed; in the other, that line was omitted. The AI system consistently ranked the non-disability version higher, asserting that the presence of disability credentials indicated “less leadership emphasis” or “focus diverted from core responsibilities.”Much Much Spectrum+1

This is discrimination by design. A qualified person with disability is judged unsuitable—even when their skills match or exceed the baseline—because the algorithm treated their disability as liability. Such distortions stem not from random error but from biased training data and value judgments encoded invisibly.

The Tokenism Trap

The bias in data is reinforced by bias in design. Disabled persons are often invited into the process only when the prototype is complete—summoned for validation rather than collaboration.

This is an audit theatre, a performance of inclusion without participation.

The United Kingdom’s National Disability Survey was struck down by its own High Court for precisely this reason: it claimed to be the largest listening exercise ever held, yet failed to involve disabled people meaningfully.

Even the European Union’s AI Act, though progressive, risks the same trap. It mandates accessibility for high-risk systems but leaves enforcement weak.

Most developers receive no formal training in accessibility. When disability appears, it is usually through the medical model—as something to be corrected, not as expertise to be centred.

Real-World Consequences

AI hiring systems rank curricula vitae lower if they contain disability-related words, even when qualifications are stronger.

Video-interview platforms misread the facial expressions of stroke survivors or autistic candidates.

Online proctoring software has flagged blind students as “cheating” for not looking at screens. During the pandemic, educational technology in India expanded rapidly, yet accessibility lagged behind.

Healthcare algorithms trained on narrow datasets make incorrect inferences about disability-related conditions.

Each of these failures flows from inaccessible prototyping practices.

Disability-Led AI Prototyping

If the problem lies in who defines legibility, the solution lies in who leads the prototype.

Disability-led design recognises accessibility as a form of knowledge. It asks not, “How do we fix you?” but “What can your experience teach the machine about the world?”

Google’s Project Euphonia trains AI to understand atypical speech. The effort is valuable, yet it raises questions of data ownership and labour—who benefits from making oneself legible to the machine?

By contrast, community-led mapping projects, where wheelchair users, blind travellers, and neurodivergent coders co-train AI systems, are slower but more authentic.

Here, accessibility becomes reciprocity: the machine learns to listen, not merely to predict.

As Sara Hendren writes, design is not a solution; it is an invitation.

When disability leads, that invitation becomes mutual—the technology adjusts to us, not the other way round.
