Add Space and Light With a Kitchen Window Bump Out

Do you crave more sunlight and airflow in your kitchen? Are you searching for creative ways to open up your home's interior? Adding a kitchen window bump out could be the perfect solution.

This clever remodeling technique extends your existing exterior wall outward to make room for new windows. The result is a wider, brighter kitchen flooded with natural light. Keep reading to learn all about the form and function of kitchen window bump outs.

Transforming Kitchens with Bump Out Extensions

A kitchen window bump out (also called a bay window) is a box-like structural projection from your home’s outer wall. It creates a small, angled nook fitted with a series of awning, picture, or double-hung windows overlooking your yard.

Unlike a classic bay window inside the home, bump outs expand the footprint of your kitchen. This added square footage accommodates wider countertops, kitchen islands, banquettes, or breakfast nooks.

Benefits of Kitchen Window Bump Outs

Kitchen window bump outs offer numerous advantages over standard bay windows:

• Increased floor space for extra seating or storage
• Eye-catching exterior curb appeal
• Improved natural lighting from multiple angles
• Better ventilation and air circulation
• Views of your yard while prepping meals

By choosing an optimal size and position, your new bump out can become a beautiful centerpiece for your whole kitchen design.

Design Considerations for Kitchen Bump Outs

Several factors influence the form and placement of your kitchen bump out extension:

• Bump out depth - Typical projections extend 3 to 5 feet from the wall.
• Window shape - Angled bay windows or rounded bow windows are common.
• Interior height - Standard height matches your countertops.
• Placement - Mid-wall bump outs maximize space and light.

An architect can help you select ideal dimensions and troubleshoot structural issues. Creative designs might incorporate corner bump outs or double-height ceilings too.

Planning Your Kitchen Bump Out Project

Like any home addition, kitchen bump outs require careful planning beforehand:

Have Professional Drawings Made

Building permits are necessary to extend your roofline and exterior wall footprint. Your contractor will create technical drawings detailing:

• Exact bump out dimensions and placement
• Structural changes like new headers or supports
• Window specifications and exterior finishes

These plans must pass local codes and ordinances before construction can begin.

Budget for All Construction Costs

Kitchen bump outs average $25,000-$35,000 installed but vary based on:

• Size of the extension
• Type of roofing and windows
• Interior finishes and appliances
• Additional electrical or plumbing changes

Omitting finishing details like cabinets or countertops reduces the price. Get quotes from multiple companies before deciding.

Hire Qualified Remodeling Contractors

Look for experienced remodelers with expertise in:

• Rerouting electrical, HVAC, and plumbing systems
• Removing exterior siding and framing new walls
• Extending your existing roofline over the bump out
• Installing windows, siding, and exterior trim

Verify they carry proper licensing, insurance, and workers’ comp before signing a contract.

Constructing Your New Kitchen Bump Out

Once permitting and prep work are complete, the real construction process begins:

Demolition of the Original Exterior Wall

First, your contractor will detach any wiring or plumbing along the exterior wall. Rotted wood or siding is replaced at this stage. New interior walls may also be framed.

Structural Framing and Roofing

Pressure-treated wood forms the skeleton of your new exterior wall. The existing roofline gets extended over the bump out and re-shingled for a seamless look.

Window and Door Installation

Next, the bump out windows and any exterior doors get professionally installed and sealed against the elements. Bay or bow windows with trim match your home’s style.

Insulation, Drywall, and Finishing Touches

After protecting against air leaks with insulation, drywall encloses the new space. Finally, exterior siding or stone matches your existing kitchen finishes.

Interior Accents and Appliances

For the full effect, add cabinetry, updated flooring, pendant lights, and other appliances to your refreshed kitchen.

Once the dust settles, it’s time to enjoy cooking in your airier, brighter kitchen. Keep your bump out windows sparkling clean to maximize natural sunlight.

Add curtains, valances, or blinds to soften the space. Place potted herbs or plants along the sills to complement the indoor-outdoor feel.

With minimal upkeep, your kitchen bump out can become a cherished space for your family to gather for years to come. The additional workspace, sunlight, and charm are well worth the investment.
