It’s called Casa de Pedra, and this place rocks - literally. The home is built from a rock/concrete mix between two honking huge boulders in Nas montanhas de Fafe, Portugal.
Said to be inspired by the Flintstones cartoon, this house was built in 1974 as a fun-loving family’s rural retreat. It is nearly perfectly integrated into the natural environment and is cute as can be.
From a distance the only indication that it is a dwelling is the roof and the oddly placed windows and smoke stack.
