Public Project Sites

SE 21st Avenue & Tibbetts Street
Crossroads Gateway

Natural Building Teacher: Becky Bee, Groundworks
Site Coordinator: Joshua Klyber, joshuaism@yahoo.com

Located at People's Food Co-op, this cob and stone gateway will welcome visitors to the store's new public courtyard and weekly farmers' market. The gateway consists of twin cob pillars sheltered by a roof of bamboo and canvas. Beside each pillar is a cob bench. A walkway will lead from the gateway to the store's new entrance. Currently under construction, the enlarged People's Co-Op will incorporate many green technologies and materials, including two ground level walls made entirely of cob!


SE 22nd Avenue & Division Street
Seven Corners Community Information Station

Natural Building Teacher: Joe Kennedy, Builders Without Borders
Site Coordinator: Pedro Ferbel, pferbel@yahoo.com

This cob and stone kiosk is located outside of the Red and Black Cafe, and provides a place for neighbors to post information about community events and news. The cabinet includes reused wood and a salvaged door, and is topped with a living roof of sedum. A colorful sunflower mosaic facing the street relates to the existing mural on the side of the cafe. A small photovoltaic panel on the south-facing roof slope will provide power for evening lighting inside the kiosk.


SE 33rd Avenue & Yamhill Street
Sunnyside Piazza, Phase II

Natural Building Teacher: Robert Bolman, President, Northwest EcoBuilding Guild - Eugene Chapter
Site Coordinator: Mark Lakeman, moontrout@cityrepair.org

A cob wall and information kiosk continues an intersection improvement process that began with a giant sunflower painted by neighbors on the street surface. An existing concrete retaining wall has been transformed into a beautiful artwork of reddish brown cob with sculpted reliefs and a fantastic mosaic. A solar-powered fountain at the corner of the wall recycles and filter rainwater harvested from the existing house's roof. The water then dissipates into bioswales containing native plantings. The cob and stone kiosk has become a place for neighbors to post community-oriented news and events inside a cabinet made of reused wood. The kiosk contains many beautiful details, is lit at night from a solar-powered battery, and is topped with a living roof of sedum. (See the Sunnyside Piazza images page for photos).
Special thanks to Tom Ullmann for providing the solar panels and supervising their installation!


SE 35th Avenue & Main Street
Southeast Uplift Information Station

Natural Building Teacher: Elke Cole, Cobworks
Site Coordinator: Diane Back, chickimonki@yahoo.com

A fanciful cob kiosk and two curved benches frame a new welcoming plaza in front of the offices of Southeast Uplift Neighborhood Program. The information station provides neighbors, staff, and community members an outdoor place to relax, meet, and talk under the arms of a giant tree. The kiosk includes a green roof, inlaid bricks and stones, and a cabinet of reused materials. The sculptural kiosk and benches are finished with cob plasters in a range of natural pigments. A foundation of reused concrete supports the structures, and the new stone paving is permeable to allow rainwater to soak into the soil.


SE 37th Avenue & Taylor Street
Memorial Lifehouse

Natural Building Teacher: Joe Kennedy, Builders Without Borders
Site Coordinator: Pedro Ferbel, pferbel@yahoo.com

This sculptural cob memorial has become a contemplative space dedicated to the memory of a bicyclist who lost his life at this intersection four years ago. A cob column with niches for flowers and other sentimental objects includes artwork made from recycled materials and bicycle parts, and is topped by a living roof. In the evenings, three fused-glass windows made of tricycle wheels filter the glow of a solar powered light. A stone LoveSeat covered with a mosaic of salvaged glass provides a resting place for passersby. This project is part of an ongoing effort by many neighbors to promote pedestrian and bicycle safety.
Special thanks to Tom Ullmann for providing the solar panels and supervising their installation!
