I have written before about Jamie Fobert’s extension to Tate St Ives, precisely because there is something about the way the project dealt with constraint that has resonated.
I should be careful here. I know enough about architecture to be interested in it, certainly not enough to tell architects how to do their jobs. But one part of the Tate project felt to me very familiar from my own work. The building had to accommodate large artworks arriving through tight Cornish streets, then somehow move them through a site embedded in a granite cliff. These were not details to solve once someone had designed the pretty bit. They helped determine what the building could be.
I was reminded of it again by something rather less glamorous: a footbridge over the railway in Wokingham.
Tan House Crossing is the sort of infrastructure most of us would ordinarily walk across without thinking much about it. Network Rail needed a bridge that could accommodate the railway beneath it, including future electrification, meet the safety requirements of a modern rail crossing and, rather wonderfully, actually get to Wokingham in the first place.
That last constraint has consequences. Large sections of the bridge were to arrive by rail, but the route to the site passed beneath another low, narrow bridge. So before anyone became too attached to a particular structural idea or a handsome form, there was a fairly blunt physical limit on how wide the thing could be.
Then there was the steel. Rather than specify a structure and order new material to suit it, the team wanted to use repurposed steel stock, because carbon. Digital modelling allowed them to adjust the structure around the sections that were actually available.
I like this because it reverses a habit that is just as common in digital work. We tend to imagine the ideal thing first, then discover the organisation, technology, regulation, budget or operating model cannot support it. At which point everything becomes a negotiation about how much of the original idea can survive. Tan House started with what was true.
That did not mean accepting a miserable result. A narrow bridge with tall protective sides could easily have become a slightly oppressive steel corridor. Instead, the structure was worked down into the sides and the parapets splay outwards, giving people more space and preserving the view as they cross. The engineering requirement is still there. You just experience rather less of it. It’s this that feels closest to the work I now do through Senvinter because lot of experience problems arrive thinly disguised as requests for a better interface, lipstick if you will on the proverbial. Redesign the search. Simplify the finance journey. Improve the checkout. Fix the navigation. Often I find a more useful first step is to map the things the interface cannot simply wish away: regulation, product rules, legacy technology, fulfilment, data, organisational ownership, decisions made elsewhere in another time.
Such constraints are not necessarily the enemy of the experience. They are the material you one has to design with.
In financial services I spent years working around rules governing what can be said, recommended or disclosed. In automotive too there are finance structures, market differences, stock systems and legal requirements sitting behind what, to the customer, ought to feel like buying a car. You can ignore those things while drawing the ideal journey, but they will still be waiting for you when someone actually tries to build it. Increasingly I think the valuable work happens somewhat earlier. Establish what is fixed. Find out what only appears to be fixed. Work out which constraint is specifically causing the problem and which ones are merely inconvenient. Then make choices around reality rather than treating reality as the disappointing phase after the workshop.
There is some genuine craft in that. Tan House Crossing is interesting precisely because the constraints are still so legible in the finished artefact. The available steel affected its structure. The railway affected its dimensions. Safety affected its sides. Yet somebody in the process still paid attention to what it would feel like to walk across.
Look, I am wary of extracting grand universal principles from a footbridge in Berkshire, but I do think there is something useful in that sequence. Understand the bounds first, then design.
AI: AI found the Tan House Crossing example as part of an occasional trawl for interesting stories aligned to the way I think. I then wrote the piece.
