From Commodity to Functionality: What Vitruvius Didn't Tell Us About Accessibility

Send us Fan MailContinuing the exploration of Vitruvius's Venustas, Firmitas, Utilitas, host Naziaty turns to Utilitas — usually translated as function or commodity — and asks what it really means in the 21st century. Drawing on a RIBA article, Accessible Architecture: How Today's Inclusive Spaces Can Help Solve 200 Years of Accessible Design Challenges, we trace the long, uneven history of disability in the built environment, from Victorian asylums and Gordon Cullen's 1931 awareness work, to Evans and Shalev's 1973 home for the physically disabled at 48 Boundary Road, to the pioneering Grove Road housing scheme by Wyvern Design Group, where disabled and non-disabled residents lived in fully integrated flats.We then pull the conversation into the present. The social model of disability has shifted the question from "what's wrong with the person" to "what's wrong with the environment," and the mantra nothing about us without us has reshaped how progressive architects work — bringing disabled users into the design process from day one. The Manchester's Hotel Brooklyn (Stevenson Studio with Squid and Motion Spot) is an example of how accessibility can be elegant rather than clinical, and looking back at an audit of an office building where the simplest oversight — access card readers mounted too high — was quietly disabling staff every day.The episode closes with an economic lens borrowed from Amartya Sen's capability approach: the gap between commodity(the thing you own) and functionality (what it actually lets you do). A standard bicycle, a standard doorway, a standard office card reader — none of these convert into equal functionality for everyone, and disabled people pay a steep "tax" of modifications, specialised tech, and extra effort just to reach the baseline others take for granted. Functionality, cannot be separated from comfort and dignity. To honour Utilitas in this century is to design for equity, not just access — and which is a conversation worth a deeper episode of its own.© 2026 Talk Architecture, Author: Naziaty Mohd Yaacob.
