What is the simplest and strongest way to join the tie-beam, post, & top-plate "IF" I want the tie-beam & top-plate flush with each other? I would like to timberframe the first floor structure along with a wood ceiling that doubles as the floor in the loft, and then just build a conventional roof on top of it along with a couple of rooms and a bath in the loft. Thanks for helping out a newbie.
