Seamlessly Expanding Your Living Space with Bay Central Builders

At Bay Central Builders, we specialize in thoughtfully designed home additions that enhance your lifestyle, improve functionality, and increase your property value—without disrupting the character of your existing home. Whether you need more room for a growing family, want to create a private suite, or simply wish to upgrade your home’s flow and design, our expert team delivers additions that look and feel like they’ve always belonged.

Types of Home Additions We Offer

Room Additions

Need an extra bedroom, office, or hobby room? We can build single-room additions that flow naturally with your home’s layout. Whether it’s a nursery, guest room, or dedicated workspace, our room additions are designed for comfort and versatility.

Second-Story Additions

If your lot size is limited but you need more space, going up instead of out is a great solution. We specialize in second-story additions, adding entire new levels with bedrooms, bathrooms, bonus rooms, or even full apartments. These additions are ideal for growing families who love their neighborhood but need more space to spread out.

Master Suite Additions

Add luxury and privacy to your home with a spacious master suite addition. We design custom bedrooms with walk-in closets, spa-style bathrooms, and serene sitting areas—all tailored to your lifestyle. A master suite addition can transform your home’s livability and market value.

Kitchen Expansions

A cramped kitchen can be frustrating. We can help you reimagine your cooking space with kitchen bump-outs or full expansions, giving you more room for countertops, islands, pantries, and modern appliances. Our kitchen additions blend functionality with contemporary design, ideal for families who love to cook and entertain.

Family Room or Living Room Extensions

Enhance your home’s communal space by expanding your living room or family room. Whether you’re looking to add square footage, natural light with larger windows, or sliding doors that lead to an outdoor patio, we create spaces that bring people together and enhance daily life.

In-Law Suites & Guest Quarters

For homeowners who need to accommodate aging parents or long-term guests, our in-law suite additions offer a perfect solution. These private living spaces often include a bedroom, bathroom, small kitchen, and separate entrance, offering both independence and proximity.

Sunrooms & Enclosed Patios

Bring the outdoors in with a light-filled sunroom or enclosed patio. These additions are ideal for relaxing, entertaining, or enjoying your garden views all year round. We design climate-controlled sunrooms that extend your living space and boost curb appeal.

Bump-Out Additions

Sometimes, all you need is a few extra feet to make a space truly functional. Bump-out additions are small expansions that make a big impact—whether extending a bathroom, adding a reading nook, or enlarging a kitchen or dining area without the cost of a full addition.
