Pittsburgh Bay Windows

Enhance Your Home With Bay Windows to Welcome More Natural Light

Extend your space beyond the walls of your home with a bay window. Three separate panes of glass are assembled together within one frame, including a fixed window in the center and operable windows on either of the sides. No matter where you place it in your home, a bay window instantly becomes a scenic focal point for both you and your guests.

Bay windows invite more natural light into your home and add space to the interior while contributing a touch of elegance to the exterior. Whatever your personal design choice, these windows can be customized in an array of styles, colors, and materials.

Commonly known as: Projection window, box bay window, oriel window

Popular Local Trends & Styles

  • Traditional Bay Windows with Curtains Bay Windows With Curtains

    Cottage-style houses are among the most popular throughout the city of Pittsburgh. Large bay windows in the living room of these modest homes invite a warm energy, and their size allows for different window treatments to suit any personal style. Covering part of the windows with sheer curtains, for example, offers enough privacy without having to sacrifice a beautiful view.

  • Bay Window Sitting Areas Bay Window Sitting Areas

    Bay windows can add depth and accentuate the exterior of your home, especially when incorporated into the classic architecture of the Tudor-style homes that are more popular than ever since first emerging in the Pittsburgh area in the 1920s and 30s. But bay windows can also serve as an intimate space on the inside. With the addition of a built-in window seat, you can relax on a lazy afternoon by cozying up in a comfy sitting area with cushions or pillows.

  • Bay Windows in Kitchen Kitchen Bay Windows

    Living rooms are typically where you’ll most often find a bay window, but consider adding one to your kitchen and upgrading the aesthetic of an otherwise practical space. It will typically require a significant amount of space, but a bay window can open up your kitchen with an abundance of natural light and offer an amazing view of the outdoors. The additional sunlight from your bay window can also be used to support potted plants or herbs.

  • Black frames on a casement window Black Window Frames

    Bright colored window frames have been increasing in popularity over the years, but the clean lines and classic look of black window frames are a growing trend in the Pittsburgh area. With the uptick in modern and minimalistic designs, more homeowners are opting for simple black and white decor. Black window frames complement a variety of design styles — especially farmhouse and rustic — and keep the view focused on the outside.

Recommended Customizations*

Take advantage of the new view or the added space. Bay windows can expand your view, even with limited wall space. But if you have wall space of 40 inches or more, the more expansive the window, the better the view. Or you can choose to add a cozy nook to your cottage-style home by adding a window seat for reading, relaxing, or gazing out into the world.
