Let's circle back to France, where this round house from 1970 is for sale.
Designed by Serge Binotto, the three bedroom property in Mirepoix in southwestern France was built for his parents. Binotto happened to be the assistant to architect and designer Jean Prouvé, which can be seen in the home's industrial and minimalist exterior.
The open living room and kitchen have floor to ceiling windows out to the front patio "slice" that keeps the home from being a complete circle. The three bedrooms and bathroom are in the back.
Believe it or not, the inside has been recently renovated (here are photos of the home's original finishings).
It is currently listed for €156,750, or about $172,000.
