Educating, persuading, selling. Semantics! People with hundreds of thousands of dollars (or most people in general) probably do not like to feel as if they are ignorant or they need some education when it comes to being sold on an idea. I'm talking about persuading.
As Daiku says, seeing one is wanting one. Are you sure that pertains to everyone? I think there must be people out there who grow to love a timberframe after experiencing one. Sure you can see the strength and beauty, but how about how the wood changes with the seasons, how one would notice sunlight in different parts of their home through the years all the things that could not be grasped immediately upon seeing one. Don't people in this scenario have to be sold upfront before they are sure? How do you make them love it before they do? How do you make them experience before they experience it?
