"Well I've never built a building before, except out of these." He gestures to the Lego. "I'd hope at least a couple of the Ura know how to build stuff like that and can tell me what to do."

That and he really doesn't want to end up as "the Bastion's carpenter" when he isn't convinced it's something he wants to do long-term. He should probably try and find someone else to teach woodworking to so he's not the only one with the skill, but that would require him to be confident that he could teach a useful amount of information to someone.
