The additional upgrades sheet only said Price on Application.
Hi Gilese,
The split level depends on whether is a two rises split level (like the pic shown) or one riser (a 340mm one riser like we will have) and on how much of the area of the house would have higher cealings because of that, etc.. ours is a 340mm step down into the living area so it means that the ceilings in the living area will be 340mm higher (in the Prosperity 23 square home) and we were quoted around $6,300 (don't have my tender here right now).
Hope that helps
