A sculptural staircase by Studio 1820, a boutique interior design studio in NYC. A soft geometric-patterned carpet wraps each tread, adding warmth and quiet underfoot, while a recessed linear LED strip runs the length of the stair wall and washes the steps in a low, even glow. A textured wall covering wallpaper above catches the light and shadow, turning a simple passage between floors into a striking architectural moment in this Manhattan home.
