Discriminatory Architecture

Image from Your Local Guardian website

Adrian Short let me know about something going on in Sutton, Surrey, at the same time both fundamentally pathetic and indicative of the mindset of many public authorities in ‘dealing with’ emergent behaviour:

An area in Rosehill, known locally as “the steps”, is to be re-designed to stop young people sitting there.

Not only will the steps be made longer and more shallow to make them uncomfortable to sit on, but no handrail will be installed just in case teens decide to lean against it.

Explaining the need for the changes, St Helier Councillor David Callaghan said: “At the moment the steps are like ready-made seats so changes will be made to make the area less attractive to young people.

It’s well worth reading the readers’ comments, since – to many people’s apparent shock – Emma, a ‘young person’, actually read the article and responded with her thoughts and concerns, spurring the debate into what seems to be a microcosm of the attitudes, assumptions, prejudices and paranoia that define modern Britain’s schizophrenic attitude to its ‘young people’. The councillor quoted above responded too – near the bottom of the page – and Adrian’s demolition of his ‘understanding’ of young people is direct and eloquent:

One thing young people and older people have in common is a desire to be left alone to do their own thing, provided that they are not causing trouble to others. People like Emma and her friends are not. They do not want to be told that they can go to one place but not another. They do not want to be cajoled, corralled and organised by the state — they get enough of that at school. They certainly do not want to be disadvantaged as a group because those in charge — you — are unable to deal appropriately with a tiny minority of troublemakers in their midst.

EDIT: Adrian sends me a link to the council’s proposal [PDF, 55 kb] which contains a few real gems – as he puts it:

I really have no idea how they can write things like this with a straight face:

“It is normal practice to provide handrails to assist pedestrians. However, these have purposely been omitted from the proposals, as they could provide loiterers with something to lean against.”

and then,

“The scheme will cater for all sections of the local community.”

Wow.

One-way screw

One-way screws, such as the above (image from Designing Against Vandalism, ed. Jane Sykes, The Design Council, London, 1979) are an interesting alternative to the usual array of tamper-proof ‘security fasteners’ (which usually require a special tool to fit and remove). There’s a very interesting illustrated listing of different systems here.

A fastener requiring a special tool is effectively addressing the “Access, use or occupation based on user characteristics” target behaviour – and is functionally equivalent to a ‘what you have’ security system such as a padlock, except that anyone can look at almost any engineering catalogue and buy whatever special tools are needed to undo most security fasteners, pretty cheaply and easily, whereas it’s still a bit more difficult to obtain padlock master keys.

However, this kind of one-way clutch head screw, which can be tightened with a normal flat screwdriver, but is very difficult to undo using any tool (without destroying it) can be thought of as addressing a slightly different target behaviour: this is “No access, use or occupation, in a specific manner, by any user”. Even if the original installer wants to undo the screw, he or she can’t do it without destroying it (e.g. drilling it out). A few of the other systems illustrated on the Security Fasteners website also have this property:

I’m particularly intrigued by the Shear Nuts and No Go enclosures (last two images above) – these two types effectively self-destruct/render themselves permanent as they are fixed into place. Something about this step-change in affordance fascinates me, but I’m not sure why exactly; it’s a similar idea to a computer program deleting itself, or Claude Shannon’s ‘Beautiful Machine’ existing only to switch itself off.

A step further would be a fastener or other device which (intentionally) destroys itself if the wrong tool (by implication an unauthorised user) tries to open/undo it, but which will undo perfectly well if the correct tool is used – along the lines of the cryptex in the Da Vinci Code, just as an ATM will retain a card if the wrong PIN is entered three times: it’s both tamper-evident and limits access. What other cryptex-style measures are there designed into products and systems?

Ann Thorpe, author of the intriguing-sounding Designer’s Atlas of Sustainability – is pursuing an interesting investigation into design activism:

Some of the basic issues around design activism include:
# isn’t all design activism?
# how much design should be activist – aren’t designers supposed to be meeting client needs?
# are there best practices for design activism?

As part of this, she’s put together a very insightful article, well worth a read, Can artefacts be activists?, reviewing some of the different approaches in this area, from Langdon Winner’s discussion of Robert Moses’ low parkway bridges, to this very website:

…[O]nce designers are out of the picture, have moved on to the next job, can artifacts in themselves be activists? Can buildings, appliances, tools, or items of clothing, in themselves, lobby for change or even “force” it?

There are some worthwhile areas of debate explored in the article, especially the extent to which an artefact can embody power or discriminate, in itself, rather than simply mediating this through the way it is used or experienced. I appreciate this argument, but (coming from the point of view of a designer), I think the intent behind a design feature is critical to understanding the issue. If a bridge is intentionally made low to prevent buses passing underneath, this may well have the same practical effect as one which is simply low through an accident of history or topography, but it displays a very different attitude and philosophy on the part of the planners. Unintended consequences of design decisions – made long before products (/systems/environments) reach users – certainly have an enormous effect on almost all human-technology interactions, but not so many are actually deliberate. No design is neutral; all artefacts embody some intent, some philosophy, some outlook, even if it’s simply “manufacture this as cheaply as possible”. All design is rhetoric, a communication of values and intentions, and can be read as a social text if that’s the way you like to think of it, but with some design, those intentions are much more obviously expressed.

I look forward to seeing how Ann’s research develops – this is a very interesting area which should probably be given more attention in design school curricula in the years ahead. As more young designers “tire of designing landfill” (can’t remember if Ben Wilson first used this phrase to me, or me to him), design activism, of one form or another, is the most meaningful route forward.

A lot of architectures of control / design with intent examples are trying to enforce what I’ve termed ‘access, use or occupation based on user characteristics’. Not all designs are especially successful at achieving that target behaviour: users will not always be persuaded, or will find ways to avoid being coerced.

Mosquito - image from Compound Security

The Mosquito anti-teenager sound device, which we’ve covered on this site a few times, was yesterday heavily criticised by the Children’s Commissioner for England, Sir Albert Aynsley-Green, launching the BUZZ OFF campaign in conjunction with Liberty and the National Youth Agency: Buzz Off logo

Makers and users of ultra-sonic dispersal devices are being told to “Buzz Off” today by campaigners who say the device, which emits a high-pitched sound that targets under 25 year olds, is not a fair or reasonable solution for tackling anti-social behaviour. The campaign… is calling for the end to the use of ultra-sonic dispersal device. There are estimated to be 3,500 used across the country.

West Hampstead Library - photo by Pashmin@ Following on from our recent look at the strategic design of public benches, BBC London’s Jimmy Tam let me know about this story in the Camden New Journal:

A public bench has been removed from outside West Hampstead Library [photo from Pashmin@'s Flickr] after it became a magnet for street drinkers.
The Town Hall now plan to use “perch” benches in the area in a bid to cut anti-social behaviour.

Singer-songwriter David Thompson, 52, of Sumatra Road, has penned a song called Menches on Benches, celebrating the camaraderie among users of public benches. He said: “A lot of people who are down and out or just high on drugs sit there at night which might be the reason they took them away, but it’s a weak society that sees removing them as the solution. You have a fellowship on the bench.”

Norma Sedler, who lives in Hillfield Road, added: “Just because a few druggies and winos started ­sitting on the seats the KGB come along and take away our lovely seats with proper backs and slats and all we have left is to sit on the pavement. When I was a kid there were always old people watching the world go by. Now I’m old myself, it’s nice if you’re going on an errand to sit down on a bench.”

Is it not the council’s action which is the anti-social behaviour here?

Rolling bench

On completely the other side of the coin, this (via) – thanks to Ray Stone for telling me about it – seems a clever piece of design which actually benefits the user: the bench surface can be rotated after it’s rained, so that a user need not sit on a wet surface. Some of the comments at YankoDesign do suggest that the underside could actually get wetter due to water running down the surface and not evaporating in the sunlight; this might be a valid concern.

Rolling Bench

Interesting, though, how quickly it was before someone commented “How long would it take before somebody rolled a homeless guy off the bench?”
