German siding and a beadboard ceiling was uncovered in the bonus room. The previous owners had nailed a heavy canvas fabric over the entire room. The beadboard will remain, but the siding will likely be removed and replace with drywall during the bathroom construction.
The backyard was also uncovered....My buddy Lee also identified several invasive species (Tree-of-heaven, etc.) that will be removed during the landscaping phase of the project.
