Welcome to Permies! Houston does not have a lot of natural building. A lot or reasons for that, but in regards to Cob, keep in mind that the soil in that area is mostly 'expansive soil'. A cob house is going to move a lot, even on a good perimeter foundation.
Austin has some cob projects. There was/is even a venue (weddings/parties, etc...) with a cob hall to rent, although that has been a few years back. I don't know if they are still in business.
