Add the Space You Need Without Leaving the Home You Love
You don't need a bigger house — you need more room in the one you have. A well-built room addition gives your family the space to breathe, adds real value to your property, and costs a fraction of what it takes to buy and move into a larger home in Mid-Michigan. We build room additions across Saginaw County, Genesee County, and the surrounding region — handling every phase from permit application to final finish so you're never left coordinating between trades.
What Kind of Space Are You Adding?
Room additions come in more shapes than most homeowners expect. Whether you know exactly what you want or you're still figuring out how to use the square footage, here's where most projects land:
- Family room addition — the most common request, typically expanding off the back or side of the home to create a dedicated living or gathering space separate from the main living room
- Bedroom addition — adding a guest room, home office with a closet, or a dedicated space for a growing family without disrupting the existing floor plan
- Sunroom or three-season room — a lighter-framed addition designed to bring in natural light and connect interior living to the outdoors, popular on properties with wooded lots or rear yard views
- Flex space or bonus room — undesignated square footage that serves as a playroom, hobby room, gym, or home office depending on the family's needs at any given stage
If you're not sure which category fits your project, that's exactly what the estimate conversation is for. We'll look at your home's layout, your goals, and your budget — and help you figure out what makes the most sense before any plans are drawn.
Matching What's Already There Is the Hard Part
Any framing crew can build a box. The skill that separates a seamless addition from one that looks tacked on is the ability to match your existing home — roofline pitch, exterior materials, interior ceiling heights, trim profiles, flooring transitions. That integration work is what Brian Shooltz has spent 20+ years getting right.
Roofline and Exterior Integration
When a room addition is built correctly, it reads as part of the original structure — not an afterthought. That means matching the pitch of your existing roofline, tying into your current siding or brick profile, and aligning windows and soffits so the exterior elevation holds together. On older Mid-Michigan homes — 1960s and 1970s ranches are common in Saginaw County and Flint-area neighborhoods — this requires real experience reading existing construction and working with materials that may no longer be in production. We've done it enough times that it's a core part of how we plan every project from the start.
Foundation and Structural Assessment
Every room addition starts below grade. Depending on your existing foundation type, the footprint of the addition, and the soil conditions on your property, we'll assess whether a full foundation, frost footings, or a slab is the right approach. We handle this evaluation during the estimate phase so there are no surprises once work begins. Homeowners in areas like Grand Blanc and Fenton often have different site conditions than those in Birch Run or Frankenmuth — we account for that before any ground is broken.
Interior Continuity
The inside of an addition has to feel like it belongs. That means matching floor heights so there's no step-down into the new space, carrying through your trim and door profiles, and tying the new room's HVAC and electrical into your existing systems cleanly. We manage the full interior scope — framing, insulation, drywall, flooring, paint — so the finished room integrates with your home rather than advertising itself as new construction.
What Does a Room Addition Cost in Michigan?
Room addition costs in Michigan vary significantly based on four primary variables: the size of the footprint, the foundation type required, the complexity of the roofline tie-in, and the level of interior finish. As a general framework:
- Smaller additions (100–200 sq ft) — typically range from $30,000 to $55,000 depending on foundation type and finish level
- Mid-size additions (200–400 sq ft) — typically range from $55,000 to $100,000 for a fully finished, integrated space
- Larger additions (400+ sq ft) — projects at this scale are priced individually based on structural complexity and finish scope
These ranges reflect quality construction with proper permitting, structural integrity, and finishes that hold up over time. We're not the lowest-cost option in the market, and we're direct about that. What you get in return is Brian on your job site every day, workmanship that shows up in your home's appraised value, and a finished product that looks like it was always there. The estimate conversation will give you a specific number based on your actual project — not a ballpark designed to get you to sign.
One Contractor. From Permit to Paint.
Managing a room addition means coordinating permits, foundation work, framing, roofing, exterior finish, insulation, drywall, flooring, and trim — and making sure every phase hands off to the next without gaps or rework. Most homeowners don't want to manage that. They shouldn't have to. We handle the full scope on every project: permit application, foundation assessment, structural framing, exterior integration, and complete interior finish. Brian oversees every phase personally. There's no subcontracted lead hand running your job while he's somewhere else. When you hire Shooltz Remodeling Advantage, you get Brian — from the first estimate conversation to the final walkthrough.

Room Addition Questions We Hear Most
How long does a room addition take to complete?
Most room additions take between 8 and 16 weeks from permit approval to final finish, depending on footprint size, foundation type, and interior scope. We give you a realistic timeline during the estimate — not an optimistic number designed to get you to commit.Do I need a permit for a room addition in Michigan?
Yes. Any structural addition to a home in Michigan requires a building permit, and in most municipalities a separate electrical permit as well. We handle the permit application process as part of the project — you don't need to navigate that on your own.How much does a room addition cost in Michigan?
Costs typically range from $30,000 on the low end for a smaller, straightforward addition to $100,000 or more for a larger, fully finished space with complex roofline integration. The biggest cost variables are footprint size, foundation type, and finish level. We provide specific pricing after reviewing your home and project goals — not before.Can you match my home's existing siding and roofline?
Yes, and it's one of the things we're most deliberate about. Roofline pitch matching, siding integration, and exterior continuity are planned from the start of every project — not addressed as an afterthought once framing is up. Brian has 20+ years of experience on existing-home additions, and the before-and-after portfolio reflects that.What's the difference between a room addition and a home addition?
A room addition typically refers to adding a single defined space — a bedroom, family room, or sunroom — to an existing home's footprint. A home addition can refer to larger-scale expansions, including in-law suites or multi-room additions.
