The PDF approach to architecture is like the easygoing, temperate wine country that we live and practice in. We work with our clients in a relaxed and informal process, that while vigorously explores our clients vision and desires, and provides for careful evaluation, is flexible, fun and engaging at every level. The wine country and much of our vernacular architecture is "materials intensive". At every level our approach in informed by working in harmony with the intrinsic natural qualities of the materials our clients select. PDF is committed to building beyond green. While dedicated to Leeds and Build It Green standards in our projects, we constantly seek to find what are often old ideas about utilizing natural site materials including adobe, stone, logs from our project site of immediate area. Wherever possible we seek to use self-finishing materials such as earth, stone, core-ten steel, and where possible we use recycled materials from local resources.
