A garden window is a compact box-bay that projects outward like a mini greenhouse, with glass on the front, top, and sides and a shelf for plants or herbs. Most often installed over a kitchen sink, it brings in sunlight from three directions and usually includes operable side vents for airflow. It’s a small footprint with a big impact on light, and a favorite for cooks who want fresh herbs within arm’s reach.

Garden Window Installation FAQs
Where is a garden window usually installed?
Almost always over the kitchen sink, replacing a standard window. The projecting box creates a sunny shelf for plants and herbs while adding usable depth.
Does a garden window need special structural support?
Because it projects and holds the weight of plants, it needs proper support brackets and careful flashing at the top and sides. We install and seal it to stay weathertight.
