Building a new house and we don’t want a step the garage into the house. What is the best way to pour the foundation to make this possible? Right now my only idea is to pour 9 ft basement walls and then pour the garage walls 20 and a quarter inches higher then that. So when you put on the floor truss and plate it the same hight as the garage floor.
Thanks for any help!!!

No universal detail
The "best way" to achieve what your looking for in your garage to house entry is to have your home designer work those specific details out in advance of building and have them approved by your building departements plan review office.
Remember that your garage floor should be "sloped to facilitate the movement of liquids to a drain or toward the main vehicle entry doorway" in order to satisfy IRC R309.1 floor surface requirements.
You Want One Step ...
You should have at least one step. I've seen "half height' steps work well. Then, combine this with vents in the garage stem wall and a drive that slopes down, away from the house.
Why? Fumes.
Cars create fumes - from their exhaust, from leaks, and from their own operation. Having a short step helps keep these fumes from flowing into your house under the door- the fumes all pas below the door threshold. With air flowing along the garage floor, fumes are also prevented from 'pooling.'
You're on the right track..
Assuming your math is correct...that will work. However, you have to be careful about concrete poured or constructed next to wood framing. Any wood framing coming in contact with the concrete should be pressure treated. Pay careful attention to the detail between the house wall/floor and the garage slab and foundation walls.
