Room Additions Lansing, MI
Make Room for What Matters
Sometimes the easiest way to solve a space problem is to change the house you already have. A growing family may need another bedroom. A cramped kitchen may need a little more breathing room. You might want a bathroom, utility room, family room, or dedicated space that simply doesn’t fit into the current floor plan.
Room additions give homeowners a way to expand the house around those needs. The new space can be designed to match the existing home while giving you more freedom to use your house the way you want.
Our Room Addition Services
Adding a room can solve a very specific problem in your home. Here are some of the services we offer:
- Bedroom additions to give growing families more room or create a dedicated guest bedroom.
- Bathroom additions when your current home needs another bathroom or a larger primary suite.
- Kitchen expansions using a bump-out or larger addition to create more room for cooking, dining, and storage.
- Family room additions that give everyone a little more space to spread out.
- Sunrooms for a comfortable, weather-protected space with plenty of natural light and outdoor views.
- Utility rooms and storage areas to give household necessities a proper place instead of taking over other rooms.
- Garage additions that provide indoor access to vehicles while adding useful space to the house.
- Custom room additions designed around your house, property, budget, and vision.
Some projects need only a modest bump-out, while others call for a completely new room with its own foundation, roof, plumbing, HVAC, and electrical work. We’ll consider what the existing home can support and what you want the finished space to accomplish.
Why Choose Maniteau for Your Room Addition?
We Know How New Construction Meets an Existing Home
Building onto an existing house requires a different kind of planning than starting with a blank site. The new construction has to connect properly to the existing foundation, framing, roof, exterior, and utility systems. Our team considers those details before breaking ground so the addition makes sense as part of the house rather than feeling like an afterthought.

One Team for Design and Construction
Our design-build process keeps the design team and production team working toward the same plan. During the design phase, we can work through the room's layout, materials, structural requirements, windows, doors, finishes, and overall style before construction gets underway. That gives homeowners a clearer idea of the project scope, budget, and schedule.

Word of mouth connection, and the work turned out amazing! I asked them to complete a custom fence job with some adaptive thought for my elderly mom’s new home, they were kind, thoughtful and it turned out better than I thought or could have done myself!

Matt and Ozzy did a great job replacing siding on my home. Would highly recommend their services for any home projects. I felt very confident in their knowledge and ability, they were very transparent and walked me through the entire process.
How the Room Addition Process Works
Start With the House and the Idea
Every room addition starts with looking at the existing home and understanding what you want to change. We discuss how you use the current space, what isn’t working, and what you’d like the new room to accomplish. A site review helps determine what is possible before the design takes shape.
Develop the Design
The design-build process brings the idea into focus. We work through the layout, room size, exterior style, materials, windows, doors, and connections to the existing house. Structural and engineering considerations are addressed as part of developing a workable plan.
Set the Scope, Budget, and Schedule
Once the design is established, we can define the construction scope and work through the budget and schedule. Required permits and local requirements also need to be addressed before work begins. Homeowners should know what to expect before the production team arrives on site.
Prepare the Site and Start Construction
Site protection comes first, followed by the construction work required for the new addition. Depending on the project, that may include excavation, foundation work, framing, roofing, insulation, plumbing, electrical, and HVAC connections. The new room is then finished and tied into the existing home.
Construction brings the plan into reality. Our team handles the work with attention to the connection between the new space and the existing house, including the structure, exterior, interior finishes, and final details.
Frequently Asked Questions
How much does a room addition cost in Lansing, MI?
Room addition costs vary considerably based on the size of the new space, structural work, foundation requirements, materials, finishes, and utility connections. Michigan projects can fall around $200–$300+ per square foot, but that range is only a starting point. A simple bump-out will have a very different cost than a full bedroom and bathroom suite.
It’s also wise to leave room in the budget for unexpected conditions, particularly when construction involves an older existing home.
What types of rooms can I add to my home?
A room addition can create an extra bedroom, bathroom, family room, sunroom, utility room, office, storage area, or expanded kitchen. Some homeowners also use additions to create private mother-in-law suites or independent spaces for family members.
Is a room addition cheaper than moving?
Adding onto your current home can be less expensive than selling and buying another property, but the answer depends on the project and your housing situation. A room addition also lets you solve a specific space problem without giving up a home, neighborhood, or community you already enjoy.
Can you add a bathroom to an existing house?
Yes. Bathroom additions are possible when the home’s layout, structure, plumbing, and available space can accommodate the new room. Plumbing access is an important part of the early planning, particularly when the bathroom will be located away from existing plumbing lines.
Do room additions require permits in Lansing?
Room additions typically require permits and must comply with applicable zoning and building requirements. Property setbacks, structural requirements, and other site conditions can affect what can be built. The specific requirements depend on the property and project, so those details should be confirmed during planning.
How long does a room addition take?
The timeline depends on the size and complexity of the addition, design and permitting requirements, materials, weather, and the amount of work needed to connect the new space to the existing home. Many room addition projects take several months from the beginning of construction through completion, with the exact schedule established once the scope is known.
Give That Empty Space a Purpose
You don’t have to settle for a house that feels too small just because you like where you live. A well-planned room addition can give your family the bedroom, bathroom, storage, or living space you’ve been wishing you had.
