Right, real big green logs were once used, but actually constructing a timber frame home requires quite a lot more skill for joinery than working with lumber, which is just nailed together. Timber framing is still around, but way, way less frequently used, since it's so expensive. It's awfully hard to work with large green wood that results in a safe structure. Don't get me started on more modern engineered wood, e.g., plywood, or stuff like cross-laminated timber. You can create your own plywood pretty easily, but it is hardly a convenient process.
