Push the wall out and let the light in.
A bay window projects outward from the house with angled side windows, adding space, light and a cozy seat to a room.
- Shape: Three windows at angles
- Extras: Seat or shelf inside

What it is, and why it matters.
A bay window is a trio of windows set at angles, usually a large center pane with two operable sides. It extends past the wall, adding a ledge for a seat or plants, and draws in light from three directions.
A bay is a bigger project than a flat window, with support, roofing and insulation to plan. We check the structure, plan the support and the small roof and finish the inside and outside carefully so it is both beautiful and weather-tight.
