Interior Design Services in Ventura County & Los Angeles

Interior design covers everything needed to plan, design and transform a space. Ours include space planning, color consultation, materials and finishes, flooring, lighting design, custom cabinetry and furniture selection, with 2D layouts and 3D renderings so you can see the result before it is built. Whether it is one room or a whole property, your designer handles the details.

Interior design generally runs $5,500 to $15,000 as a project fee, depending on the number of rooms and the scope of the project. Larger homes and custom work can also run higher, and your written estimate confirms the exact price. Your designer breaks down the expected costs at the start.

The scope determines the time. Simple projects could take only 2 to 3 weeks, while comprehensive redesigns with multiple rooms take longer. Having one designated designer keeps communication simple and avoids delays.

An interior designer handles both the structural and aesthetic sides of a space, such as layout planning, building codes, function and renovation work. A decorator focuses mainly on visual elements such as colors, furniture and accessories. RnD Builders also provides full interior design, from layout changes to finishing touches.

A professional helps you avoid costly mistakes, makes decisions faster and makes sure the space is both beautiful and functional. Because RnD Builders is also a licensed contractor, your design is drawn with construction, permits and materials in mind.

It is not required, but it helps most when a remodel involves layout changes, multiple rooms or many material choices. A designer settles the plan, finishes and budget before construction, which keeps the project on schedule and the result cohesive.

One room is fine. In addition, many clients start with a kitchen, a primary suite or a living room, and others redesign a whole home. Tell us the scope at the consultation and we will price it accordingly.

You meet with your dedicated RnDesign designer to go over your goals. You can bring a concrete vision or only a vague idea. The designer works with you until they fully understand your tastes, and by the end you receive an initial timeline estimate and a rough budget outline.

Yes. We are a licensed design-build contractor. After your final approval we submit plans to the local authorities when needed, and the same company can build the project, so nothing is lost between design and construction.

Your designer breaks down the expected costs from the start, and each selection goes into your written estimate so you can see how it affects the total. We also work to keep the project in line with the budget agreed in your contract.
