These Naperville, Illinois, homeowners and their two teenagers wanted to transform their semifinished basement into a space where they would all enjoy spending time. Interior designer Christie Kenny planned it to include a wine bar, lounge, fireside seating area and game room. She plucked its black, white and charcoal tones from a new Cambria countertop slab in the bar area to create a glamorous palette with high contrast. The result is an industrial chic lounge vibe. With their saves to ideabooks, Houzz readers made it one of the most popular basements of 2021.
