I do not know where to begin to get this into the as-built remodel plan.  We are remodeling the kitchen and the stairs from the entry level come right down into the kitchen area on an angle! The house is built on a hill and the garage, entry, powder and laundry are on this mid level, then it goes down to the dining room, kitchen, & family.  Second story goes up from the entry and are the bedrooms.   
  
There is no way to render or do perspective views without including these stairs.  I do not have the original blueprints and the clients are sure not going to pay me to measure their whole house for a kitchen remodel, so just need to get an approximation!  I would appreciate any advice on how to set this up if someone has encountered this layout before.   
I've attached a photo and thanks again!  Looks like I lost my signature info etc. when ChiefTalk became "forums".
