Recreating an Eichler isn't as simple as it sounds. Building codes have changed, with new requirements for insulation and wiring, for example.

Some of the original materials are now "endangered," according to the International Union for Conservation of Nature and Natural Resources, and others are considered toxic.

The 2013 Eichler homes, just like the originals, are expected to emulate Frank Lloyd Wright's "dry construction" method, which meant having no applied finishes -- no paint, wallpaper or plaster, according to Monique Lombardelli, who plans to built individual Eichlers.

"Wood is wood; brick is brick; concrete is concrete," she said.

Here's a comparison of materials that were used to build an Eichler and those that could be used in 2013.
