I've been looking at literally hundres of floor plans while planning on building using ICF.
I first look to see if I like a plan, then look to see if the second story aligns atop the first, assuming this
is most suitable for ICF building.  Am I wrong in this, can you cantilever the second floor out over the first?
What if the second floor dimensions are 'smaller' than the first floor?

I've attached a picture of the specific cantilever I had in mind.
thanks in advance

Well you really aren't going to be able to "cantilever" the second floor out like in the picture. However you could have it engineered to have a steel beam the would be supported along the outside egdes of the second floor and then the ICF walls could start from there and continue up. Hope this Helps

I can cantilever the second floor out over the first with little or no problem. The more the offset, the more it costs. Send me a set of house plans and I will give you a cost to build.

Hi bp:

A picture does not provide enough details regarding cantilevering possibilities. As a Structural Engineer I want to emphasize that Reinforced Concrete design, which is the basis for the structural aspect of the ICF, offers enormous opportunities in designing to suit desired form and aesthetic appeal.

The best way is to consult your Architect and Structural Engineer to chalk out the possibilities -- and I am sure they can team up to meet your expectations of form and aesthetics -- and to not only understand your needs and desires but perhaps even suggest some modifications both for practicality and to enhance economy in design/construction and aesthetic appeal.

I guess the simplest thing to do would just be to extend the lower walls out and eliminate the cantilevers.

Any advice on selecting homeplans, etc?
