More room for the life you want to live. KoBolt Construction helps Orange County homeowners plan and build additions, ADUs, and major remodels—with clear communication from the first conversation to the final walk-through.
A detailed scope and regular updates help you understand the work, ask informed questions, and make decisions as your project moves forward.
We look at how the design, structure, and construction fit together before work begins, so important questions can be addressed early.
Construction affects everyday life. We treat your property with care, keep work areas organized, and work to minimize disruption throughout the build.
You may love your neighborhood but need more space. Or your home may have the right footprint and a layout that no longer works. A good construction project starts by understanding that problem—not by jumping straight to finishes.
Based in Fullerton, KoBolt Construction brings planning, design coordination, and hands-on construction management to home additions, ADUs, and major renovations. Founder Nelson Moreno combines a civil engineering background with construction experience to help connect the big picture with the details that make a home work.
You can expect an itemized proposal, straightforward conversations about scope, and regular progress updates. Explore our design-build process to see how an idea becomes a plan, a proposal, and a completed project.
Choose the service that matches your goal. We will help you understand the planning and construction involved before you commit to a scope.
Add the bedroom, living space, or expanded kitchen your home is missing. We plan additions around the existing structure and layout, so the new space feels connected to the home you already enjoy.
Create a separate living space for family, guests, or potential rental use. We help you work through ADU planning, design, and construction, with the needs of your property and future occupants in mind.
Improve the space you have with a better layout, an updated kitchen or bathroom, or a coordinated whole-home renovation. We manage the work as one project, from structural considerations to the finishing details.
Our project gallery includes home additions, ADUs, kitchen renovations, bathroom remodels, and structural updates in Orange County and nearby communities. Look through the photos and project details to find work related to your own plans.
