Home Additions in Walnut Creek & the East Bay
Make room for the way you live. Rojas Construction & Remodeling helps homeowners plan and construct home additions with attention to the existing house, structural connections, and finished details.
A useful addition starts with a clear plan
Whether your goal is more living space, an expanded kitchen, or another room, we discuss how the new space will connect to your home. Foundation work, framing, utilities, and finishes need to work together.
Define the work before construction
Approved plans and engineering guide the construction. We clarify the scope, material selections, responsibilities, and scheduling before work begins. Requirements vary by property and city.
Tell us what you need
Share your city, the space you want to add, and any plans or measurements you already have. We can discuss the next steps toward a project scope.
Home addition questions
Where does the project start?
Start with the space you need and how it should connect to your home. Existing conditions, design, structural engineering, and local approvals guide the construction scope.
What affects the budget?
Size, foundation work, roof connections, utility changes, access, and finishes affect pricing. A written proposal should identify included work and any separate design, engineering, or permit costs.
Can the house stay occupied?
That depends on the work and how it affects access, utilities, and safe separation from construction. Discuss occupancy and disruption during planning.
