Chicago and its suburbs are an architectural playground. Drive from a historic Chicago bungalow belt to a gated subdivision in Oak Brook, and you will see a stunning variety of home styles.

When it comes time to replace your windows, you can’t just pick a style at random. The wrong window on a historic home looks like a cheap suit—it just doesn’t fit. To maintain your home’s character (and its resale value), you need to choose a window style that respects the architecture while delivering modern efficiency.

Here is a guide to the best window styles for Chicago homes and Oak Brook estates.

1. The Double-Hung: The Universal Classic

Best For: Colonials, Cape Cods, and Traditional Brick Homes.

If you draw a picture of a house, you probably draw it with double-hung windows. These are the most common style in the Midwest. They feature two sashes (top and bottom) that slide vertically.

• Why it works: It is timeless. For the stately Georgian homes found in Oak Brook, double-hung windows with traditional grid patterns (muntins) are essential to maintaining that historic symmetry.

• The Modern Twist: Newer models allow both sashes to tilt in, making them incredibly easy to clean from the inside—a huge plus for second-story bedrooms.

2. Casement Windows: The Modern Choice

Best For: Modern Farmhouses, Contemporary Homes, and Ranches.

Casement windows hinge at the side and crank outward like a door. Because they don’t have a center rail (check rail) like a double-hung, they offer an unobstructed view of the outdoors.

• Why it works: For the sprawling ranch homes in the western suburbs or modern remodels, casements offer clean, simple lines.

• The Hidden Benefit: They are the most energy-efficient operable window. When the wind blows against a casement window, it actually pushes the seal tighter against the frame, eliminating drafts.

3. The “Chicago Bungalow” Style

Best For: Historic Chicago Bungalows (obviously) and Arts & Crafts homes.

The Chicago Bungalow is a local icon. Originally, these homes featured distinct window groupings—often a large picture window flanked by two smaller double-hungs.

• The Mistake to Avoid: Many homeowners replace these artful groupings with a single giant slider to save money. This ruins the historic “face” of the home.

• The Right Choice: Stick to the “3-lite” design. Use a fixed center window for light, with operable double-hung or casement windows on the sides for ventilation. Keep the upper sash smaller (or gridded) to mimic the original Craftsman look.

4. Bay and Bow Windows: Adding Dimension

Best For: Victorians and Living Room focal points.

If your home feels flat or dark, a bay or bow window literally pushes the room outward.

• Bay Windows: Three panels (usually a picture window in the center with two angled flankers). These create a deep seat perfect for reading nooks in Oak Brook estates.

• Bow Windows: Four or more windows arranged in a gentle curve. These look fantastic on Victorian turrets or large master suites.

5. Specialty Shapes: The Custom Touch

Best For: Tudors and Custom Luxury Homes.

Walk through a high-end neighborhood, and you will often see arched tops, circles, or gothic peaks.

• Why it works: These are architectural jewelry. On a Tudor home, a diamond-grid pattern or a gothic arch is critical to the style.

• The Upgrade: Since these windows usually don’t open (fixed), they are great candidates for triple-pane glass to maximize energy efficiency without worrying about weight.
