Such a welcome feeling on a cold snowy day when you know that the inside is warm and cozy.

These south windows bring in the sun for warmth and light for the plants.

This is just clay soil, sand and straw which was used to plaster the interior side of the straw bale walls.

This is what the greywater planter looks like under construction.

The first layer of ¾" river rock allows the greywater to move freely from one end of the planter to the other. Roots from the plants "clean" the water of nitrates better than standard septics do.

Cob is an ancient method of building with earth. Using the same formulation as the plaster, clay/sand/straw, "cobs" are placed on the wall and formed together to make a beautiful wall. See the next pic for completed wall.

The 2' thick wall really shows here. These windows were found at a used building materials store.
