Cost lever
Bay window
Three panels — a flat center parallel to the wall with two angled sides — that project out to make a small alcove.
What it means for you
Buys you a window seat or display ledge and floods a room with light from three directions. It's a structural project (the projection needs support and a small roof), so it costs well above a flat window of the same width.
Where you'll see it
Living and dining rooms and breakfast nooks; a common “feature window” upsell.
