Small on demand water heaters, a/c units, heat pumps and exchangers kinda negates the need for cellars these days.  Not like you need a root cellar anymore!  All your mechanical systems would fit in a closet.
 its the frost that is the issue here.  
I have already gone thru the planning commission, with any luck 4 models will be up end of September  start of october.  Its all at the mercy of the supply chains now.  Day after planing commission  made the info public I got almost 400 calls from re agents.  Its like um, can I get the roads in 1st please.  
Its one of those things I am willing to bet by the end of the year all the major tracks will have a model for this  style of home.   Not to mention that we are using icf.  Which is not really done here ( once again I have no clue why, its perfect for here)
