Home Addition in Moraga

Moraga Home Additions

Expanding and modernizing your living space with Moraga’s premier design-build experts.

From building expansive in-law suites on sprawling ranch properties to executing massive second-story pop-ups, we create additions that elevate your home’s value and functionality. Our all-in-one approach means the designers who imagine your new space are the same people ensuring it gets built perfectly.

Expanding Homes Across Moraga

Suburban lots in Moraga offer fantastic potential for expansion. Whether the goal is to stretch a single-story home further into a large backyard or to build upward to capture rolling hill views, these large-scale additions require meticulous planning. We take the time to evaluate the structural integrity of your home to ensure these grand visions are safely and legally achievable.

Geotechnical and Foundation Planning

Large expansions often require extensive grading and new concrete footings. We conduct necessary soil evaluations to ensure the new foundation will remain stable and perfectly level with the existing house.

Navigating Easements and Setbacks

Even on large lots, property easements and strict Town setbacks dictate where you can build. We cross-reference your property survey with local zoning laws immediately to establish a viable buildable area.

Tying into Existing Rooflines

A sprawling addition can easily look disjointed if the rooflines clash. Our architectural team expertly designs complex truss systems to weave the new roof seamlessly into the old one.

Sequencing for Suburban Life

While a major addition is a massive undertaking, your life still needs to function. We help you prepare for the disruption by establishing a clear timeline and erecting heavy-duty barriers to keep the dust out of your living space.

Home Addition Process

1. Initial Site Visit: 1 to 1 ½ hrs

Every home addition begins with a clear understanding of your existing home and how you want it to grow. We start with an on-site walkthrough to evaluate current conditions, understand your goals, and discuss how the new space should function, feel, and connect to the rest of the home. By listening closely to your vision, questions, and budget, we help shape an addition that feels intentional, well-integrated, and built for long-term comfort.

On-site walkthrough to evaluate the existing structure, site conditions, and how the addition can best integrate with your home
We provide a free ballpark construction cost range for the addition, for example $180k – $240k, based on size, complexity, and scope
To move forward, we execute a preconstruction agreement (PCA), covering architectural coordination, engineering, and permit planning
Home addition design can range from straightforward expansions to highly complex projects, depending on structural constraints, zoning, and client selections

2. Design & Material Selection: 1 -2 months

Once the vision is clear, the design process puts it all on paper. Every detail is considered, from the countertops, to cabinet layout, to lighting, we will figure out every last detail. A thorough design phase is key to staying on budget.

In-depth consultations for all project goals and design considerations.
Some common design goals include careful layout for cabinet use, best lighting options, countertop / flooring selection as well as overall colors, finish fixtures.
The contractor creates an all-inclusive list of all project selections for client review, which will be used to guide the project.

3. Permitting: 2 - 3 months

Once the design is complete, it’s time to submit the plans to the city for approval! This can take a few months, but during this time you can still keep the project moving! While most product selections will have already been considered, this is the time to actually start shopping for certain items, in most cases top on that list is tile to allow for precise layout of fixtures, niches, and other elements that may be involved.

4. Construction: 1 - 4 months

Finally, our team begins with a careful protection of your surrounding areas. Dust barriers with zipper doors, HEPA air filtration, and floor protection are some of the methods we implement to ensure your home and family are protected from the process. A dedicated project manager and construction team will carry out the work in close coordination with the homeowner, providing clear communication, organized scheduling, and day-to-day oversight to keep the project running smoothly and predictably.

5. Move In

Once final city inspections are approved, we complete a detailed walkthrough of the new addition to confirm all work, systems, and finishes are complete and performing as intended. We then review and deliver all close-out documentation, including manuals and warranties, and provide a long-term maintenance overview to help ensure the addition integrates well and performs for years to come.
