A garden window is a type of window that projects outward from the wall of a home or building and creates a small, greenhouse-like space. It is typically installed above a kitchen sink, but can be placed in any room that gets enough sunlight.

Garden windows have four glass sides, with two side vents that can be opened to allow for ventilation. The top of the window is usually sloped to allow rainwater to run off, and a shelf is typically installed inside the window to hold plants or other decorative items.

One of the main benefits of a garden window is that it allows homeowners to grow herbs, flowers, and other plants indoors year-round. The window's design allows for plenty of natural light and ventilation, which can help plants thrive. Additionally, the window provides a unique and visually interesting addition to a home's interior and exterior.

However, it's important to note that garden windows can be more expensive than traditional windows, and installation can be more complicated due to the need for a supporting structure to hold the weight of the window. Additionally, care must be taken to prevent moisture buildup, which can damage both the plants and the window itself.
