Title says it all.  I have a complete plan with an existing foundation, first and second floors, plus complex roof.  The plan represents the current state of a rehabilitation of an 1860s farm house that was built in three phases.  The house was raised and a complete new 9' poured concrete foundation unifies the three prior foundation sections.  All good.
 
	 
 
	Now the owner wants to add a covered porch across the front that works with the existing two story section yet merges with the roof line of the one story portion of the home.  I think I have managed that but the last twist has baffled me - how do I arrange things so the porch floor/deck level is a step down from the first floor which is at relative elevation 0?
 
	 
 
	I've included a screen shot of the exterior with the porch at the same level as the first floor.
 
	 
 
	Any suggestions?
