My spouse and I are building a new home in rural ND designed to look like a 1906 farmhouse (based on my grandparents farmhouse.)

In an effort to reduce costs, we are considering using hardi-plank on the front of the home and ______ on the sides and back. I say blank because we can not determine if vinyl, steel, seamless, etc. would work.

Does anyone have any experience/suggestions for us? The sales person at the local building supply store said this is done often, but I look at a LOT of houses and I've never seen it...

Can you help us?
