The house at the right is in a neighborhood in Bethesda, right across the DC line in Maryland.  It's neighbors are pretty architecturally diverse, but typical of homes built between 1930 to 1955.  Some of them can be described on the MRIS profiles as "farm houses" and some are bungalows, a few cottages and, yes this place, which falls under "other".

It is the infamous "Mushroom House".  I've driven by it  lots of times showing other houses in the neighborhood, and my buyers have not generally thought of as a selling point.   

And I have to wonder, what were the owners thinking when they remodeled and reinvented what probably started out as a mid-century colonial?  

I've seen my share of odd houses.  Some are what we call "buyer specific", appealing to a few people, but the few who do like it really like it a lot.  But if the mushroom house ever came onto the market, who on earth would the target market be?  How do you find the probable purchaser for this place?
