Inside a bunker-like kids’ room, arched raw-concrete walls and a skylight frame a rope-slung hammock bed over cork flooring. A matte black wood stove burns beside a porthole window, with firewood stacked under a simple wood bench. Open pine shelves display wooden toys, tufts of moss, and an aqua glass jar, while glass terrariums add life. Blue quilted bedding and a chunky throw soften the industrial shell, merging survivalist utility with playful comfort.
