Creative Recycling for Green Buildings
Ralph Crawford will share experiences gleaned from his projects regarding: demolition for salvage, processing old materials, structural considerations, alternative ways to design around codes, aesthetics, financial considerations of DIY building, diverse skills and interests, motivation and passion for recycling, and interfacing with neighbors and authorities.

Ralph knew he would build his own home as early as his pre-teens, perhaps because an admired uncle had done so.  While working at Stanford University Medical Center as a construction project engineer, he bought a small turn-of-the-century cottage with no foundation but with an extended family of termites.  With a low budget and his own labor, Ralph acquired salvaged materials from a variety of sources, including a slaughterhouse and Port of Oakland warehouses.  He designed the house around the available salvage and overcame the hurdles provided by the building department regarding used materials.  Also recycled were a furnace and heating ducts, iron drain pipe, electrical panels and breakers, gas piping, toilets and sinks, marble tops, garbage disposer, structural steel, and redwood water tanks.  Since then he has also worked on properties in Idaho and Napa using salvaged materials.  

The principals of Berkeley's Leger Wanaselja Architecture, Cate Leger and Karl Wanaselja, will speak about their practice of "green" architecture over the past 20 years which has aimed to create beautiful and enduring buildings while reducing their environmental impact.  They are best known for their innovative use of materials including used shipping containers, salvaged street signs and junked car parts.  Looking at recent projects, they will define green architecture and discuss its challenges and how they achieve their goals.

Cate Leger and Karl Wanaselja both received their M.Arch degrees from UC Berkeley in the early 90's.  Prior to joining together to create their own firm, Cate worked at William McDonough Architects and Sim Van Der Ryn Architects, and prior to graduate school, she spent five years in Washington, D.C. as an environmental advocate working for nonprofits, the  Environmental Protection Agency, and Congress.  Karl has been building since 1982 and obtained his California General Contractor License in 1992.  In Graduate school, he won the prestigious Branner Travelling Fellowship for design excellence. He has worked with concrete, wood, steel, adobe, and straw structural systems, and also has extensive experience in the use of salvaged materials.

Leger Wanaselja Architecture has won several awards and been featured widely for their innovations in green architecture.
