I'm a novice 4 year user now using HD Pro 15. I want to design an elevated structure where the ground floor structure is precast concrete piers with break away panels between the piers. The ground floor is only for parking, beach gear and access to stairs/elevator. The real living levels will start at an elevation of 11 ft above the ground floor for code. I am planning on three total true living levels, two primary living levels plus a tower, above the ground level. I've tried this before and am never sure whether to build the ground floor as a basement/foundation or as floor 1, with floor 2 being the first real living area.
Any thoughts/advice? Here's an "example" of the structure style I'm looking to design
