Discovering Portland's organic architecture

I’ve just spent the better part of a week in Portland, Oregon, hanging out amidst a living experiment that might just point the way to the future of the North American city. The Planet Repair Institute headquarters, once a typical West Coast style home on a typical West Coast street, has been modified by owner, architect Mark Lakeman and an ever-changing crew of cob builders, natural plasterers and urban permaculturalists into an earthy badger mound of mmm-mmm, organic goodness.

Lakeman and his many collaborators espouse a kind of participatory architecture in which everyday people learn how to use common natural materials such as straw and clay to make architectural interventions that help humanize urban neighborhoods. The result is a kind of re-organic-ization of the built environment, a softening of the predominantly rectangular aesthetic with blobby, communal pizza ovens, loaf-like street corner benches and hobbit-worthy backyard pavilions. These cheerful earthen structures, encrusted with whimsical mosaics and botanically themed bas reliefs, may have the form and texture of supersized Christmas cookies, but I believe they also suggest something much more profound.

Here is a handmade, participatory architecture that seeks to re-design the city from the bottom up, in marked opposition to the traditional top-down impositions of architects and urban planners. The handmade nature of the building technique invites participation, and the constructions take on the character of those who work on them, a truly open source methodology that, with minimal instruction, even young children can learn by molding clods of mud into the cob material that can be then patted into almost any shape imaginable. As an added bonus, the clay used is in abundant supply at local cemeteries and can be had for the asking. It is an inevitable byproduct of the many holes that tend to be dug in that business. The sand and straw constituting the rest of the mix are likewise easily sourced and are of course inherently natural and biodegradable.

Aside from the biomorphic look and the participatory building process, I think it important to point out that Planet Repair’s architectural methodology is often used to ‘re-skin’ existing structures, making them more ecologically sustainable by adding substantial insulation and thermal mass to both the insides and the outsides of buildings, as well as conferring a pleasant, natural aesthetic. The inside walls of the front room at Lakeman’s southeast Portland home have been retrofitted in an extra layer of stuffed straw soaked in a slip of clay, considerably upping the building’s ‘R’ value and giving it a lovely grassy ambiance. Out the back, his office in the former garage has been ‘frosted’ on its outside walls like a yummy birthday cake with layers of earth-toned cob replete with arboreal design motifs.

This is architecture as palimpsest, a refreshing contrast to the tear-down mentality of many urban designers who in the past have been all too eager to raze the embedded history of locality in the service of their personal vision. The re-use and re-skinning of existing structures has an environmental benefit as well, keeping demolition debris out of the waste stream and reducing the need for newly manufactured materials. Given the the global ecological and economic crises, this approach makes more and more sense.

Saying the climate movement is a failure and we should give up is not an option.
