Village Building Convergence 2010

Welcome to the Village Building Convergence, a true gem about Portland and one of my personal favorite things about the city.

Each year, an organization called City Repair puts on a ten-day festival of community building and place-making, often using natural construction to do so. It's wonderful, 25 sites all across the city welcomed community members to join in playing in the mud while creating beautiful meaningful relationships and simple projects along the way. I was honored to be one of their guest instructors this year and participate in many of the activities throughout the week.

An intersection painting, brings neighbors together in the street and helps slow down traffic with it's thoughtful design. There are many of these throughout Portland, how many have you seen?

A cat palace, built last year and led by my dear friend Eva Miller,

and this year she's building a Chicken Palace.
What lucky animals in the urban place!

She also led the renovation of the City's first legal Light Clay-Straw Retrofit.
And it came out great!

Here's a detail picture of the wall section for all you builder nerds

My awesome new friend Fezzo who was my housemate for the week.
and his bright red kilt that we dyed together mid-week.

This project was my favorite--an outdoor classroom at Madison High School. The timberframe and main cob walls had been built the previous year. Now we are adding strawbale ampitheater style seating and some bamboo and sculptural cob.

I have never seen as enthusiastic cobbers as here!
What a huge batch!

Rachel gets into it

Beautiful lime finishes from the prior year

Wetting down the top of the wall so that we can add to it this year. An amazing attribute of natural construction, that it is forever mendable and able to be rehydrated and continued.

Sebastian works on a bamboo detail.

Casey lays out the bale seats.

Then the seats are cover with slip and cobbed together, making it very strong.

We sculpt a sun at the center point of the top

Many, many people are involved with making it happen

Across town, at another project site, I lead a plaster workshop.


We are applying the final coat of plaster on a cob bench built the previous year.



Ellen has a great time finishing the project, she has put a lot of energy into the transformation of her backyard into a food forest sanctuary and community garden. She can't wait to enjoy using the bench!



So excited for next year, please check out www.cityrepair.org for more info, and see you there!

'Living Walls' plaster over an 'EcoNest' -- Working with Lime

Alright, this had been a big job, and hence, haven't written in a while. But finally finished and what a good one it has been! Especially for those of you interested in the super flat and super refined earth plaster style. Good to practice.
The structure is a heavy timberframe with a mixture of traditional european and japanese joinery and infilled Light Clay-Straw. It was designed by Paula LaPorte and the construction was led by her husband, Robert Laporte, of EcoNest. My mom was at the straw-clay workshop for this structure, where I got introduced to the project from early on. Little did I know, six months later, when the walls were thoroughly dry, I would be on a team of four to plaster the whole thing.

For this project, I joined the crew of Living Walls, a Portland-based earth plaster company, led by Joshua Klyber. We did a lime plaster system on the outside and earth plaster with aliz on the interior. And we had a lot of fun! This post will focus on the lime plaster portion and my next will cover the earth plaster work. Enjoy!

The site and our mortar mixer set-up.

the fun part!

classic Econest!


This finish is at minimum a seven-pass system. First, we prime or lathe all windows edges, corners and other expanses of wood. Then we apply the rough base coat of lime plaster which has a lot of gravel. Next we press the plaster with a wood trowel to compact the lime as it dries. Then we score the surface with a small rake or scarifier. Then we come around again with a finish coat, no gravel in it this time. We follow again with a hard-packing motion with a wood trowel. Then we brush all the loose sand from the surface. Finally we apply a lime wash to give the surface color, actually two coats. So in all, we have come around to every square inch of this exterior wall surface nine times. Labor intense, no joke!
