A growing family, a crowded kitchen, or a need for a quieter room can make a familiar home feel too small. A home addition gives you the opportunity to change that without starting over somewhere else.
KoBolt Construction plans and builds home additions in Fullerton and across Orange County. We consider how the new space connects to the existing structure, roof, circulation, and daily use of the home—not just how much square footage can be added.
Tell us what is no longer working and what you want the additional space to do. We will help define the planning and construction needed to move forward.
An extra bedroom, a larger gathering space, or an expanded suite each calls for a different plan. We begin with how you want to use the addition.
We review the existing home and the proposed work together, including structural connections, layout, and construction access.
Design, permitting, trades, and finish decisions need to work together. We manage the construction details and keep you informed as the addition takes shape.
The best addition solves a real problem. It may create a comfortable bedroom, make room for family gatherings, or connect a kitchen with the spaces around it. Our job is to help the new area function as part of the whole home.
Planning includes a review of the proposed scope and how it can be built. Our design-build process brings the drawings, project proposal, and construction sequence together. You can review the design and understand the work before construction begins.
Visit our room additions page for ideas focused on bedrooms, offices, and other individual spaces.
What affects the scope and budget?
Size is only part of the picture. The existing structure, foundation work, utilities, access, and finish selections also shape the project.
Will plans and permits be needed?
The requirements depend on the work and the city reviewing it. We discuss the planning and approval steps as part of defining your addition.
Can an addition be part of a larger remodel?
Yes. Our project gallery includes additions coordinated with kitchen, bathroom, and living-space renovations.
