Kitchen Addition & Bump-Outs Contractor In Greater Lansing
Stop struggling with a cramped kitchen. Our custom bump-outs and additions create the open-concept space you need for cooking and entertaining.
If your kitchen is the bottleneck at every holiday with no room for an island, no space for a walk-in pantry, and guests stacked into the hallway, the problem isn't your cabinets — it's your footprint. We build kitchen additions and bump-outs for homeowners across Lansing, East Lansing, Okemos, Holt, Haslett, and surrounding Greater Lansing communities. As a home addition contractor in Greater Lansing we transform cramped utility kitchens into chef's social hubs by pushing the exterior wall out, removing load-bearing walls with engineered headers, relocating gas and water lines, and delivering seamless flooring transitions that make the new space feel like it was always there. We engineer every project below Michigan's 42-inch frost line and manage all permitting from start to finish.
Kitchen Addition Challenges We Solve for Homeowners
No Room for an Island or Pantry
We push the exterior wall out and reconfigure the layout so an island and walk-in pantry fit the way you’ve always pictured them, not as compromises, but as the focal point of the space.
Load-Bearing Walls Blocking an Open Floor Plan
We remove load-bearing walls and install engineered LVL headers sized to carry the load properly, so you get the open sightline to the dining or living area without compromising your home’s structural integrity.
Gas, Plumbing, and Electrical in the Wrong Places
Expanding a kitchen footprint almost always means relocating gas lines, water supply, and drain lines, and electrical circuits; we handle this work in-house rather than outsourcing, so the rough-in is coordinated with the framing from day one.
Flooring Transitions That Look Like an Addition
We plan the flooring transition between old and new from the structural level up, so the finished surface reads as one continuous space rather than an obvious seam where the addition begins.
Fortified Structural Work
A kitchen bump-out only performs well long-term if it’s properly tied into the existing structure. Engineering decisions (not finishes) determine how well the addition holds up over time.
- Frost-depth foundations: Footings are poured below Michigan’s 42-inch frost line with insulation to prevent movement and seasonal shifting.
- Engineered LVL beams for wall removal: Load-bearing wall removals are structurally calculated to ensure proper load transfer and long-term stability.
Mechanical Coordination
Kitchen additions require careful coordination of plumbing, gas, and electrical systems alongside structural work. When planned together, the entire build runs more efficiently and passes inspection without delays.
- Gas line relocation: Gas lines are properly sized and permitted to match appliance requirements and safety codes.
- Drain and supply routing for island sinks: Island plumbing is planned before flooring is installed to ensure proper drainage and hidden routing.
Tailored Layouts
A kitchen addition that works for a 1,200-square-foot ranch in Holt is a different project than one for a two-story colonial in Okemos or a cape cod in East Lansing. Homeowners in Waverly, DeWitt, and Haslett all have different lot constraints, foundation types, and exterior profiles that affect how a bump-out gets designed and tied into the existing structure. We start with your home's actual conditions before we produce a single drawing.
- Island sizing and traffic flow: Kitchen islands are designed with proper clearance to support both everyday use and entertaining.
- Exterior material continuity: Siding, roofing, and trim are matched to the existing home so the addition blends naturally with the original structure.
Why Choose Custom Built for Your Kitchen Addition?
- 20+ Years of Local Experience: Kitchen additions are more complex than they look. We've spent two decades navigating the structural, mechanical, and zoning realities that come with expanding a kitchen in Mid-Michigan, from load-bearing wall removal to rerouting plumbing and gas lines through an existing foundation.
- Design-Build Means Your Kitchen Actually Works: A kitchen addition requires your designer and your builder to be in constant communication. Because we handle both under one contract, your layout decisions get pressure-tested against what's actually buildable before a single wall comes down.
- We Handle All Permitting: Kitchen additions trigger multiple inspection types including structural, electrical, and mechanical. We manage every application, schedule every inspection, and handle every township or city requirement so you never have to navigate a building department on your own.
- Lifetime Workmanship Guarantee: We stand behind the structural and finish work we build. If something we built fails, we fix it, no questions asked.

Kitchen Addition & Bump-Out FAQs for Lansing, MI Homeowners
How much does a kitchen addition or bump-out cost in Lansing, MI?
Kitchen bump-outs in the Greater Lansing market typically range from $40,000 to $90,000, while full additions that reconfigure the entire layout run $90,000 to $180,000, depending on scope and mechanical complexity. We provide detailed line-item estimates after a site assessment, not flat-rate numbers that shift once we open the wall.
How long does a kitchen addition or bump-out take in Lansing?
Bump-outs with mechanical work run 8 to 14 weeks from permit approval, and full additions run 12 to 20 weeks, plus 4 to 6 weeks for design and permitting on the front end. We build year-round on a realistic Michigan construction calendar, not a best-case scenario.
Do I need a building permit for a kitchen addition in Lansing?
Yes. Any structural expansion, including a bump-out, requires a building permit, and gas, plumbing, and electrical work each carry their own trade permits. We manage the full permitting stack from initial application through certificate of occupancy, so you never file anything or attend an inspection yourself.
How does Michigan's climate affect a kitchen bump-out or addition?
Footings go below the 42-inch frost line without exception, and we use closed-cell spray foam at the rim joist and exterior wall transitions to prevent vapor drive where old and new construction meet. These are baseline standards for a Michigan build, not upgrades.
What kind of warranty comes with a kitchen addition from Custom Built?
Every kitchen addition carries a lifetime structural warranty on framing and foundation work, plus manufacturer warranties on windows, roofing, and appliances passed through in full. We're a local company. Our accountability to this community doesn't end at the final inspection.
