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?

You're right. What were the thinking?!?
I ran across and honest to goodness Geodesic Dome in Takoma Park once. The owners had about 5000 sq ft of vacant lot (except for the trees and the 45 degree slope) they wanted me to sell. That was the last time I tried to sell raw land.
The Dome was pretty interesting. They were living in it and everything. Ya gotta love Takoma Park.
Pat;
The phrase, "You gotta kiss a lot of frogs..." comes to mind... Perhaps a toad would love to live under this "toad-stool" ... or mushroom? I have no idea... just a thought! Although I can see Sally's idea ... fairy, too.
Karen Anne -- Not this artist type..LOL
Maybe a buyer with a servere vision impairment would like it. Or J.K. Rowling.
How do you find the probable purchaser for this place?
You put out an All Point Bulletin for those Keepler elves. That band of merry little flour monks bake a mean cookie.
Sally, you are too goofy!
Barbara, I only took a couple - the neighbors were eying me suspiciously!
Ken, I'll be you know - what is that funny spacecraft looking structure along Rt 29 near Columbia?
