Kitchen Addition in Danville

In Danville, the kitchen is more than a place to cook—it’s where families gather and memories are made. If your current kitchen feels outdated or too small, a kitchen addition can dramatically improve the way you live.

At Royalty Builders, we design stunning kitchen expansions with open layouts, upgraded appliances, custom cabinetry, and gorgeous finishes. Whether you’re dreaming of a chef’s kitchen, a breakfast area with bay windows, or more prep space for entertaining, we’ll create a kitchen that fits your lifestyle and complements the elegance of your Danville home.

Bathroom Addition in Danville

Adding a new bathroom can make a significant difference—whether it’s a guest bath, an extra full bath for kids, or a luxurious en suite. Royalty Builders specializes in bathroom additions that combine spa-like comfort with everyday practicality.

We manage the entire process, including plumbing, layout design, tiling, and premium fixtures. Your new bathroom will feel like a natural part of your home while offering the modern comfort you deserve.

Sunroom Addition in Danville

Danville’s sunny, temperate weather makes a sunroom addition a beautiful and practical upgrade. Whether you envision a bright space for reading, entertaining, or indoor gardening, a sunroom creates a seamless connection between indoors and outdoors.
