4 design secrets of the hexagonal honeycomb

Formed by bees heating up and rocks cooling off, hexagons inspire modern design both aesthetic and functional.  Read on to experience how the 6-sided polygon interweaves physics and life, process and pattern, past and present, in a dizzying, epoch-spanning array of forms created by function.

1. Maximum honey, minimum wax.

The honeycomb is an elegant design solution that allows bees to store the maximum amount of honey with the minimum amount of wax. In this quick video tour of the evolutionary math behind the honeybees’ “modern” design, TED ED describes how the hexagon beat out circles, triangles, squares, and pentagons as the most elegant, and efficient, answer to the honeybees food-storage question.

2. Angles determined by bee heat!

No honeybee ever “did the math” to determine precise angles, nor do contemporary honeybees calculate angles. Over time, honeybee bodies evolved to automatically deposit wax in hexagonal shapes by internally warming and cooling in a pattern that would perfectly shape the flow of wax! According to a study posted at AskNature.org:

“Here we show that honeybees neither have to measure nor construct the highly regular structures of a honeycomb, and that the observed pattern of combs can be parsimoniously explained by wax flowing in liquid equilibrium. The structure of the combs of honeybees results from wax as a thermoplastic building medium, which softens and hardens as a result of increasing and decreasing temperatures. It flows among an array of transient, close-packed cylinders which are actually the self-heated honeybees themselves.”

Pirk, CWW; Hepburn, HR; Radloff, SE; Tautz. 2004. Honeybee combs: construction through a liquid equilibrium process?. Naturwissenschaften. 91: 350-353.

3. Hexagons appear, disappear, and reappear in evolutionary history

Geologists note  that the hexagon is also a shape that worked for prehistoric coral, as shown in the fossil at right.

Living between 460 and 273 million years ago favosites coral featured tightly packed hexagonal calcite columns that sheltered marine polyps who extended tentacles to extract prey from the seawater around them.

Small gaps in the calcite walls allowed the polyps to share nutrients, while the hexagonal walls allowed individualized organisms to stay as closely packed with minimal structural material.

4. Angles determined by rock cooling!

Stumbling upon perfectly geometric columns of rock can only be described as magical. Even the most austere scientist might find herself (or himself) gaping in awe at the flawless shapes and wondering if men or Gods carved those immaculate columns.

In a fascinating twist of physics, hexagons are also formed by igneous rocks cooling off!

When objects contract, they often crack or fracture. When contraction occurs at centers which are equally spaced, then a hexagonal fracture pattern will develop. If the contraction is not evenly spaced, then other geometries of fractures, such as 5-sided or 7-sided fractures, may occur.

Quotes from American Geophysical Union Georneys blog

The democratic design of Bill Coperthwaite

“A Question: Why is it that other cultures… had such beauty about them in their daily lives–and we have not? Is it important? I suspect that it is extremely important for ourselves, for our children, and for our friends that we seek to surround ourselves with beauty. Suspicions: I suspect that how a culture defines beauty greatly affects its success as a culture. I wish I could persuade our world to see life itself as a work of art…”- Bill Coperthwaite in A Man Apart: Bill Coperthwaite’s Radical Experiment in Living

sexist asshole

There is no rootsier a designer than Bill Coperthwaite, whose lifelong and stalwart commitment to the handmade, the simple and the beautiful, and to design as a way of life, set him apart from nearly everyone. Many know Bill as an innovator of wooden yurts from his life’s work adapting Mongolian round houses. Indeed he built over 300 wooden yurts around the world, often fantastical, often multi-tiered, likely no two exactly alike as he was always perfecting his designs and trying new ideas.

A new book by his friends Peter Forbes and Helen Whybrow takes us deeper into Bill’s world. Painted in letters, stories, and a narrative spanning the couple’s experience building a yurt at Bill’s homestead, are Bill’s philosophy of democratic design and experiential education, his fascination with handmade craft the world over, his 50 year remote homestead on the Maine coast, and his thoughtful, if difficult, relationships with those he loved.

Human habitat, artfully rendered and free of the trappings of modern mass production, is now rare, and I seek it out whenever I can. Indigenous cultures struggle to maintain or revive their time-hewn methods under the crush of Western homogenization and occasionally, individuals also emerge here and there who are able to imagine – and build – something authentic and free. The process of creating this is what Bill Copperthwaite called “democratic design” and I have come to call “wild design.” Design that by its existence, keeps real another way of living on earth, one that puts authenticity and meaning above the banal push for profit and personal gain. One that requires relationship – between people and land, between generations, between cultures. One that demonstrates that people can create shelter that is both deeply human (expressive, artful, unique), and also natural (designed to decompose, to create conditions conducive to life, to ingeniously embody the natural patterns that structure our world).

Visiting the habitat of such wild designers is a treat! In a whimsical twist of fate, I was fortunate enough to be part of the yurt build described in A Man Apart and have included some photos of my time to compliment this nod to Peter and Helen’s excellent book. Go get the book and have a read to travel deeper: A Man Apart: Bill Coperthwaite’s Radical Experiment in Living. And then start designing. And building. The cultural impetus for democratic design has never been greater.

Bill built the yurt by hand, a few miles walk from the nearest road, with no access to power tools and all materials carried in by foot or canoe.  Peter and Helen relate in their book that Bill actually began by building the top two stories, and some time later, on his own and without benefit of power tools, jacked these up and built the ground floor workshop.

Bill’s yurt sometimes are built with a temporary tripod holding up a circle, in this case a bike wheel, that the roof is constructed around.

Bill believed the confluence of experiential education and hand made craft presented a great antidote to the despair of industrialized versions of both. He earned a PhD in Education from Harvard, teaching design/build through the construction of a wooden yurt on the Harvard campus that would serve as his classroom in the 1960s.

Here I am, receiving instruction from Bill on how to build this fantastical design.

Since the 1960s, Bill made his designs available to others through poster instructions that you could get through written order. He liked to provide just enough information to get a new yurt-builder going, but also require her to think!

Osa Peninsula outside in – a visit to Ojo del Mar

Like a novel written by a poet, the wild architecture of German artist Mark Huebner is a hand-wrought meditation on place and the senses. Here we wander the winding pathways of Ojo del Mar, the solar-powered “simple life retreat” Huebner created with Niko Fischer, and explore an artful world where human habitat plays with that of howler monkeys, scarlet macaws, and green iguanas.


An accomplished artist as well as author of a cadre of intricate bamboo timber works, Huebner’s vision has truly flourished at Ojo del Mar, where the pegged bamboo structures and hand-made furniture are carefully crafted of and with their jungle landscape.


Ojo has been an experiment in tropical architecture that skips foreign and unsustainable building materials. The elegant result embraces its location on a rugged beach adjacent to one of Costa Rica’s wildest and most biodiverse national parks.


Huebner has learned the hard way that the Osa peninsula’s intense weather swings and aggressive jungle make it a tough place to build anything that lasts, especially if you’re trying to avoid concrete. In order to maintain structures that withstand searing heat and off the charts humidity, endless insects, and pummeling rainy-season downpours, Mark has made a few concrete concessions and replaced some aging bamboo with eucalyptus poles. But for the most part, his “casa grande” lodge, 10 or so guest and staff structures, and all the furniture, are hewn from pegged bamboo and hardwoods grown on or near the property and finished with natural oils.


Ojo’s casa grande hosts a formal dining space, barefoot lounge extraordinaire, open-air whole foods kitchen, and guest library. It’s also a timber-framed shelter and rainforest art installation, a delightful study in both intricacy and economy of design. 


Huebner built a scale model to scheme out Ojo’s casa grande, now collapsed and tucked in the shed. Originally built with bamboo, the casa grande’s lengthy timbers were replaced with eucalyptus after a decade or so of tropical living. Huebner prefers building (and re-building) light and temporary, acknowledging the jungle will take it all back in the end anyhow.

Niko’s cooking is fresh fish forward, with a yummy and educational emphasis on local fruits and vegetables.


Abundant tropical flowers are grown on site and artfully arranged in all the structures.

A former agricultural area, Ojo has been re-cultivated as an extension of the wild rainforest protected in nearby Corcovado National Park. Structures are small and scattered along winding paths that tour dense jungle gardens. Since the grounds are actually a regenerating ecosystem with a diversity of habitat niches, guests are treated to close encounters with acrobatic howler and spider monkeys swinging through the upper canopy, a colorful company of lizards and frogs sharing the walkways, and a perpetual symphony of bird song and fluttering wings as bright hummingbirds, parrots and trogons go about their daily business.


Huebner has re-thought the western bathroom, replacing it with outdoor showers and sinks, and hand-sculpted, plumbed outhouses.

Each guest space is unique, but all carry similar elements and are artfully designed and curated for ‘outside in’ living.


Nature’s forms are on display, gallery like, everywhere you turn!

“Bamboo is not only sustainable, it’s sexy,” says Huebner.


Abundant heliconia flowers delight birds and butterflies alike.


What would a Costa Rican lodge be without a yoga studio? Ojo’s beachside studio hosts a variety of wellness retreats.

Each unique guest cabina is open to the rainforest, and located on its own winding path. While Ojo’s typical guests are certainly not of the high-brow wealthy set, increasing Western visitors and expats in a region where people make $3 per hour is creating tension on the Osa Peninsula. Huebner opts to prevent theft through maintaining long term relationships with local community members, as well as individual lock boxes (handmade, of course) in each guest space, rather than the heavy security and barbed wire fencing used at some resorts.

Quiet beaches dot the Matapulo coast, reached by a 45 minute, jarring drive on a pot-holed dirt road from Puerto Jimenez. This one’s a short, barefoot walk down the beach from Ojo del Mar.


With limited wifi (Niko offers her phone as a hotspot when needed) and abundant ocean-view hammocks, guests can disconnect and reconnect.



Thanks to Mark and all at Ojo del Mar!

Field-based design studies – Vermont

In the summer of 2013, the Nature of Design collaborated with Yestermorrow Design/Build School by leading it’s Semester Program students on an orientation wilderness design immersion in Vermont’s Green Mountains.


Students hiked from shelter to shelter along a high ridge, stopping to participate in a number of design exercises along the way, with nature as studio.


Students would go on to spend a semester working intensively together to design and build an entire house, so we wanted them to have an opportunity to get to know one another, and learn to communicate and work together.


The course invited students to shift into deep observation mode, to quiet their minds, and practice following nature’s forms.


Students speculated on the function of the structures they encountered, and how these might be taken as design inspiration.


Everywhere, constantly, natural forms presented themselves for closer study.


Students worked in teams to create installations using natural media. People got the feel of working in a studio with no furniture, walls, computers, and definitely no fluorescent lights. How does constant, dynamic physical movement change brain activity, and thus learning and the creative process?


Though students ranged in age from 19 to 43, emphasis was on interaction with the natural world, on inquiry, and on play.


Not only were students constantly surrounded by opportunities for visual design studies, but with several days’ walk separating them from most sounds and smells of civilization, quiet minds and absence of constant electronic distraction allowed for extended focus and attention


The only textbooks we brought were field guides.


The result was a lot of spontaneous laughter, comfort with curiosity, willingness to try new things.


There was time for small details and acknowledgment of other species’ serious design skills.


There was also time for individual reflection, unstructured conversation on the trail, and just being.

Students shared their work, and offered feedback.

Projects were intended to bring nature into the design process, and to stimulate leaps between disciplines.

Students connected what they saw with information from other studies.


Because the students would go on to design and build a tiny house as a collaborative process, we wanted to practice talking things through, to play with how to build a group aesthetic, and explore the iterative process of executing a collaborative design.


We loved experiencing what the students created, but the emphasis was on process.


Yestermorrow’s Semester Program in Sustainable Design/Build draws students from all over the US and the world. This diversity made for lively discussion, and dynamic interplay of ideas.


Heading back to Yestermorrow’s campus down in the Mad River Valley, there was time for a cleansing swim in the Mad River.


The Mad River offered ample opportunity to observe the endless forms water creates in itself, on rock, and around our bodies.


Our hope was also to invite students to re-examine their role as humans, and human designers, working between nature and culture.

Presentation for 2013 Biomimicry 3.8 Global Summit and Education Conference

Here’s what I’ll be presenting Saturday at 1 pm at the 2013 Biomimicry 3.8 Global Summit and Education Conference in Boston.  It doesn’t make as much sense without narration, but does feature some pretty pictures!

Photosynthetic Neighborhoods

Photosynthetic Neighborhoods by Henry S. Horn is a piece featured in Princeton’s 2013 Art of Design online gallery. In it, the “artist” – professor emeritus of Ecology and Evolutionary Biology at Princeton – contrasts the cellular cluster of plant leaves with an aerial photo of an American neighborhood. He writes:

Leaves carry out photosynthesis in clusters of cells locally serviced by end-units of pipes hat deliver water and take away sugar. The cells must be within diffusion distance of pores to exchange carbon dioxide and oxygen. Diffusion may set an upper limit on the size of an efficient cluster, and quasi-fractal branching of pipelines may set a lower limit. Accordingly, many species of local woody plants show photosynthetic clusters of approximately uniform size, and these clusters themselves group hierarchically into neighborhoods of successively larger sizes. The photo fields are 4 millimeters wide, except for the aerial photo of human neighborhoods.


Seaweed ladies & moss men

Why do these images of seaweed ladies and moss men matter to designers? Because each is mirror and portal. Not of what you should make, but of who you could be.

Take Me Outside

Singing just past the threshold of what I have tried to say, the gorgeous Laura Mvula offers a brilliant invitation to get outside, get barefoot, and sit in the green garden.
