Sculptural Glass Walls for Effortless Indoor–Outdoor Flow

This folding system dissolves the boundary between home and horizon, bathing rooms in silvery light. I love the ultra-thin stiles and frameless direct-glaze panels—they read crisp and modern, like tailored millwork. Style it with pale oak floors and linen drapery to let the architecture sing. It’s a quietly luxurious essential that elevates daily living with ease.
