Why Choose Mulberry as Your Home Addition Builder in Columbus
Full-Service Design and Construction
Your designer and team of builders stay in constant communication. That keeps everyone aligned on one goal: bringing your vision to life.
Builders First
We’re builders at our core, with over a decade of experience bringing complex projects to life. If an addition is structurally possible and city-approved, we have the expertise to make it happen.
Seamless Integration
A well-executed addition should look and feel like it was always part of your home. Our team works to match your existing exterior so the result is cohesive inside and out, like sourcing original builder specs and matching bricks or colors.
Transparent Budgeting
Every line item breaks down clearly and aligns with your budget. You’ll never have to worry about hidden costs or mid-project surprises.
Dedicated Project Manager
From permitting through punch-list, your Project Manager coordinates all trades, manages the schedule, and keeps you updated every step of the way.
Home Addition Pricing
The cost of a home addition builder in Columbus can vary widely. Pricing depends on the size and type of addition, the complexity of integrating it with your existing home, and the materials and finishes you choose. Construction elements like foundations, framing, roofing, mechanical systems, and interior finishes may all be part of the final cost, depending on project specifications.
At Mulberry Design + Build, we focus on early budget conversations so expectations are clear from the start, because transparent planning protects your investment.
Types of Home Additions We Complete
If it’s structurally possible and approved by your city code, our experienced team can build it. As a contractor for home additions in Columbus, some of the most common types of projects we handle include:
In-Law or Rental Suites
First-floor suite additions designed to comfortably accommodate aging parents, extended family, adult children, or guests, with thoughtful layouts that offer privacy and independence while keeping loved ones close.
Master Suite Additions
Expand your primary bedroom and bathroom footprint for more space, more seclusion, or direct access to your backyard. Ideal for homeowners who love their home but want a more elevated retreat.
Garage Additions
Detached or attached garage additions that add functionality, storage, and curb appeal—designed to integrate with your home’s existing architecture.
Square Footage Expansions
Add livable space to recreate or open up your existing floor plan. Whether it’s a larger kitchen, an extended living area, or a new flex room, we design additions that improve the flow and function of your entire home.
Second-Story Additions
For homes where expanding outward isn’t an option, building upward can be the answer. Second-story additions require careful structural evaluation and planning—exactly the kind of complex work our team is qualified for.
Frequently Asked Questions About Design-Build Home Additions
A home addition makes the most sense when you want to create more space in your house—whether that’s because you’re welcoming a new family member, or the layout no longer fits your lifestyle. If your location is right and the home is sentimental, an addition lets you stay rooted while getting the extra square footage you need. It’s also a smart alternative to buying or building new, considering the significant costs and disruption involved in moving.
Not always, which is why it’s important to work with an experienced team before committing to a plan. The most common limiting factor is lot size: if there isn’t enough land to expand within local zoning requirements, certain additions may not be feasible. Homes can also be impacted by HOA restrictions, which often govern details like exterior finishes, colors, styles, and amenities—all of which need to be factored into the design. Our team evaluates these variables early in the process so you know what’s possible before design begins.
We can construct almost any type of home addition. We’ve built in-law suites, master suite additions, garage additions, second-story additions, and large square footage expansions that reconfigured the layout of the entire home. If you have a vision for how you want to grow your space, we’ll tell you honestly what’s achievable and design from there.
In most cases, yes. We can reach out to the original builder to obtain exterior specs, which builders typically keep on file. If the builder’s records aren’t available—or if the home is older and the builder is no longer in business—we work with expert vendors to color-match, brick-match, and source comparable materials. In some situations, a full exterior refresh may make more sense, especially if the existing exterior has significant weathering or damage. We’ll walk you through the options and help you decide what’s right for your home and budget.
The right time to start is whenever you have a clear plan and a qualified builder. Time of year doesn’t matter: our Project Managers build weather contingencies into the schedule and coordinate trades to keep things moving. While weather like heavy snow or flooding can delay excavation, that’s a scheduling factor we manage—not a reason to put your project on hold indefinitely.
Each project timeline is different, because it depends on the size and complexity of the addition. For example, second-story additions and larger expansions usually take longer to complete than straightforward suite or garage additions. Your Project Manager will develop a detailed schedule during pre-construction, so you know exactly what to expect at each stage before any work begins.
That’s one of the most important design challenges in any addition—and one we take seriously. Before construction begins, we create detailed renderings so you can see exactly how the addition will integrate with your existing layout and exterior. On the interior, our designers ensure the new space connects naturally with the rooms it adjoins. On the exterior, we focus on matching materials, rooflines, and architectural details so the addition looks like it was always part of the original home.
Managing a home addition requires coordinating architects, engineers, permit runners, and multiple trades—all while trying to stay on top of the rest of your daily life. At Mulberry, our seamless design-build model puts all of that under one roof for you. Designers, Project Managers, and trade partners are all aligned on the same plan, so your addition is built exactly as you intended—without the coordination headaches that come from managing it yourself.
Absolutely. We serve Columbus and all of Central Ohio, including most locations within about an hour of the city. If you’re not sure whether your home is inside our service area, reach out and we’ll be happy to discuss your needs.
