Off Highway 280, there's a house in Hillsborough that looks better suited to the town of Bedrock. Yes, the "Flintstone House," as it's affectionately known, has been something of a roadside attraction since its construction in 1976 as an experiment in new building materials. Designed by architect William Nicholson, construction involved wire mesh and steel rebar on inflated balloons, then layered with shotcrete (concrete sprayed through a hose, basically).

So if you'd like to stand out, and you're not worried about that construction or the place's former disrepair in the '80s, there's good news. Now, as CBS and Curbed report, it's on the market for what could be $4.2 million.

Originally, the house was an off-white, but it's been a weird orange since the early 2000s. Eccentric Bay Area architect and designer Eugene Tsui performed a Seussian remodel of the interior around that time. Here, some screenshots of that from CBS.

Curbed confirmed that the house is on the market via Alain Pinel Realtors, but the $4.2 million price tag is being reported as "rumor."
