There is just something about sheetrock. When lumber turns into walls and the spaces are all defined, it turns a construction site into a home.

A sheetrock crew arrived Wednesday and it looks like they're going to finish the entire job today. Sounds of drills and hammers and a bustle of people, that's happiness in custom home construction. They are fast and efficient.

While we are using regular sheetrock in the bulk of the house, we've chosen to use Dragon Board—a waterproof, fireproof, mold-proof, fungus-proof, impact resistant construction board—in a number of places. If we could have done the whole house in it, we would have. It's an ingenious, durable product, but the cost is still prohibitive for large jobs.

We'll use the Dragon Board in the high-water areas: bathrooms, kitchens, laundry. We're also using it for the attic flooring (the only place that doesn't have concrete floors) and the stair treads.
