Lost our home to a fire in January. Finalizing plans for our forever home. Plan on ICF. Wife and I were flirting with idea of putting in a partial basement (full basements are very rare around here). I was talking to one of the icf reps and he told me I couldn’t. It had to be a full basement or none. I ask him why and he said it had to do with the weight of the walls. I planned on putting the partial basement under the center of the home. I thought as long as the basement walls and the house walls both had their own foundations it would be ok but he said no. Is this correct? Has anyone done a partial basement under icf home? House location is in Oklahoma.
