Custom Kitchen Additions in Hillsborough

The kitchen is more than just a place to cook—it’s the heart of your home. In Hillsborough, where timeless architecture and modern luxury come together, a custom kitchen addition is a transformative investment. Whether you’re dreaming of an open-concept chef’s kitchen, a bright breakfast area, or a show-stopping entertaining space, our team designs kitchens that are both elegant and practical.

We take into account every detail—from natural light and sightlines to storage, workflow, and premium finishes. Expect custom cabinetry, spacious islands, upgraded appliances, and seamless integration with your existing home layout. With Royalty Builders, your new kitchen won’t just function better—it will feel like it’s always belonged.

Stylish Bathroom Additions in Hillsborough

A well-designed bathroom addition can elevate your comfort and your home’s value. From spa-worthy primary baths to compact powder rooms and luxurious guest suites, we create bathrooms that feel like retreats—complete with top-tier finishes and thoughtful details.

Our Hillsborough clients often request marble counters, soaking tubs, curbless showers, heated floors, and custom vanities—all of which we design and install with expert craftsmanship. Every layout is tailored to your space and needs, ensuring that plumbing, lighting, and flow are efficient, elegant, and timeless.

Sunroom Additions in Hillsborough

Let the outdoors in with a sunroom designed for year-round comfort and natural light. A sunroom addition is perfect for Hillsborough’s picturesque surroundings and mild climate, offering a space that’s flooded with sunlight and connected to nature—without exposure to the elements.

Whether you want a cozy reading nook, a light-filled lounge, or a serene indoor garden space, we design sunrooms that feel bright, open, and peaceful. We use energy-efficient glass, insulation, and transitional design elements to ensure your sunroom feels like a true part of your home—not just an add-on.

Functional Room Additions in Hillsborough

Sometimes you just need more room—and we make sure every square foot works beautifully. Whether you’re adding a guest bedroom, home office, playroom, or home gym, we design functional spaces that meet your evolving lifestyle without compromising the aesthetic of your home.

Our team ensures that every new room integrates seamlessly into your floorplan, maintaining flow and balance while optimizing light, storage, and livability. In Hillsborough, where luxury meets livability, your added space should feel every bit as refined as the original home—and with Royalty Builders, it will.

Second Story Additions in Hillsborough

When lot space is limited but your needs are growing, building upward is the answer. A second-story addition can dramatically increase your living space—adding bedrooms, bathrooms, home offices, or even private retreats—without changing your home’s footprint.

We handle everything from structural reinforcement and architectural planning to stair design, HVAC upgrades, and finish work. And because we specialize in Hillsborough homes, we ensure that the exterior materials, rooflines, and detailing align perfectly with the original design—creating a cohesive, elevated living experience that feels custom, not cookie-cutter.
