Is it a wall that's actually a window? Or a window that's actually a wall? Either way, this house in Antwerp has the ultimate indoor-outdoor connection: an entire wall of glass that opens completely to the outdoors.
In designing an addition to an existing city row house, Belgian architects Sculp IT were looking for a solution that would bring light deep into the house, and connect the new spaces with the back garden. They accomplished this in a big way with a 20 foot high, four ton set of folding doors. You can think of them as a great big French window — the largest pivoting window in the world.
Opening the window has the effect of turning the indoors out, effectively making the entire extension, including a second floor office that overlooks the kitchen and dining space, a part of the garden beyond. The island pictured above is on wheels, so that it can be rolled onto the patio for outdoor cooking and entertaining. The designers thought of everything — except, it appears, window coverings. If you're going to live in a house with one of the world's largest windows, you definitely can't be shy.
