A garden window is a lovely way to add natural light, showcase plants, and add character to the home. It protrudes from the house, encased in glass on all sides to let light in from every angle. It has a deep-set base, and you can add a middle shelf for extra display space. As the name implies, a garden window is commonly used to grow houseplants or a small herb garden. They have a fixed top and front and two working side windows to allow for cross ventilation.
