  • Just build less

    This post has moved.
    It now lives on the Constructivist blog: read the updated version →

    Eiffel Over is now my stage for engineering-related clowning, singing, dancing and writing — you’ll find my professional writing on design and regenerative thinking over at Constructivist.

    More and more people are asking: how do we move from sustainable design to regenerative design?

    In these conversations, we often talk about system change. We talk about strengthening the connection between designers and the origins of their materials. We discuss unlocking symbiotic loops in material supply and enabling designs that best serve the local ecosystem. All of these changes are essential—and they’ll take years, even decades, to fully implement.

    But these conversations can be a distraction from a much more pressing, if uncomfortable thing we can do to shift our industry towards more regenerative ways of working. Given the massive contribution that construction makes to greenhouse emissions and the massive impact it has an habitat destruction, it is simply this. 

    We must build much less stuff. 

    Build less is writ large in the IStructE’s Hierarchy for Net-Zero Design. And while this hierarchy focuses on carbon, given the impact that material extraction has on habitat loss, there is a strong case that building less will significantly reduce our impact on ecosystems too.

    Of course, there will be things we need, structures we can’t do without. But once we set the intention to build less, we can redirect our creativity as designers toward adapting and thriving with what we already have.

    We’ll still need to build some—but we can, and must, build much less.

  • Stuffed crust geometry

    At some point in my childhood, Pizza Hut introduced the stuffed crust pizza. The idea was simple: stuff the crust with a ring of gooey cheese. It was fine when you had a slice from a large pizza, but on a small pizza, the balance was off—too much crust and not enough topping.

    I haven’t thought about stuffed crust pizzas in decades, but they help illustrate an important point in geometry. As a pizza gets bigger, the ratio of crust to surface area gets smaller. So a small pizza has lots of crust, while a large pizza has relatively less crust per unit of topping.

    In general, this is expressed as the ratio of a circle’s circumference to its area, which decreases as the radius grows. A small circle has far more edge per unit area than a large one. This is why my small stuffed crust pizza tasted too crusty.

    But this post isn’t just about childhood pizza or geometry. It’s about the importance of edges in systems. How much “edge” we have shapes how we interact with the wider environment and how systems function internally. It affects the design of buildings, cities, and infrastructure. 

    But that’s more than I can stuff into this post—more tomorrow.

  • Field notes from chaos

    The wind was getting up. The waves were starting to blow in from different directions. The sea scape seemed to be changing at random. The day before, the waves had been rolling in with a nice rhythm.

    This is another blog post that comes from the sea. And this one is about chaos. One characteristic of chaotic systems is the rules of the system keep changing. And this seemed to be what was happening around me. The wind was gusting from different directions, the tide was turning, the sun was coming in and out from behind clouds. And all of this was making a chaotic mess of the surface of the water.

    Standing there trying to figure out what was going on I started to think about ways of coping with chaos. Think of these as working notes rather than a developed theory. 

    Get into the field – the sea looked messy from the shore but only in the water could I really feel how changeable it was. 

    The signal in the noise – there can be a lot of randomness but are there underlying patterns. There did seem to be a beat of waves heading in to the shore, confused by another set rolling in from the side. When you find a pattern in the system it is easier to work with. 

    Notice when the pattern ends – the rules of chaotic systems change. A pattern in the system is only useful as long as it persists. Look out for the pattern changing. 

    Think on your feet – you can’t rely on the normal patterns of working (see yesterday’s post on creating cycles in work). Instead you have to make the most of the situation you are in. 

    Learning is difficult – if learning relies on loops of action and reflection, then learning is much harder when the conditions keep changing.

    Chaos is tiring – if you are constantly on alert trying to figure out what is going on then you are not getting time to rest and recuperate. 

    Writing these notes up I am left wondering:

    • How can we support ourselves, other people and organisations when they enter into periods of chaos?
    • How might our own actions, behaviours and design decisions cause chaos for others?
    • How might we design for increasing chaos as climate breakdown rolls on?
  • What if every time we built something the world got better?

    What if every time we built something the world got better?

    It is a simple question. What if every time we built something the world got better? Not just in the places we construct but in all the places affected by our construction activities. If we could meet this apparently simple ask, then we would shift the construction industry from a paradigm of extraction and damage to a paradigm of healing and repair.

    In our groundbreaking new book, James Norman and I explore what it would take for the construction industry to make this shift and what role structural engineers have to play in this transition. In short, what it would mean to be a regenerative structural engineer?
