Paint it Black

Idée Concrète: To get a concrete look for the floors throughout the house, the team first considered Pandomo flooring, a slick treat-ment that would be even more expensive than a standard finish.

In the end, instead of a concrete look, the couple went with actual concrete—at a fifth of the price.
