Farm House on a Hill

I am looking to have someone design a custom home for me. Ive got a general idea of what i want it to look like (i found a home on the internet that i didnt hate) there are just some features (ceiling heights, room sizes, etc.) that i dont like. Would love to get some help customizing this house.
