St Louis Bay Windows

Bay Windows Add a Timeless Touch to Traditional Homes

Bay windows are one of the most unique types of windows, adding architectural interest by jutting out of the wall. In a city that celebrates fine architecture, bay windows create an eye-catching focal point that enhances the look of your home.

While the style was popularized in the Victorian era, bay windows have maintained their popularity over the years because they bring many benefits beyond architectural interest. Because bay windows are actually a combination of three windows angled together, they provide more natural light, ventilation, and space in your home. In the St. Louis area, bay windows commonly consist of a picture window with double-hung windows flanking each side.

Commonly known as: projecting window, square bay window, box bay window, oriel window, 45-degree bay window, 30-degree bay window

Popular Local Trends & Styles

Bay Windows With Curtains

Bay windows create an angled interior wall that leaves many homeowners searching for the right window treatment. Blinds or shades can cover each individual window in the combination. But curtains are the most popular window treatment in the St. Louis area. Bay window curtain rods are adjustable and angled to fit your space so you can hang curtains to cover the entire bay window.

Kitchen Bay Windows

Bay windows open up space for nice little nooks in living rooms and bedrooms. They can also be used as an add-on to your dining area. Large kitchen bay windows can open up enough space for your table and chairs. Or you can use the extra space to create a window seat or bench. Across the kitchen, bay windows are great additions above your sink or food prep area to bring light to a typically dark space.

Craftsman Style

Craftsman style homes were popular a century ago. The style has come back to life in new constructions in St. Louis suburbs like Kirkwood because it blends well into traditional neighborhoods while providing modern influences. Bay windows are common feature of Craftsman bungalows, a smaller, more economical subset of the style, because they add natural light and interest in limited wall space.

Victorian Bay Windows

The Painted Ladies of Lafayette Square are the city’s most famous homes. These stately Victorian style houses are known for their bold color palettes and ornate architectural detail. Wooden bay windows were common in these traditional homes and are still popular in renovations. Wooden windows offer more prefinished color options to create bold, impactful exterior color.
