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:

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.

Experience With Homes Across Mid-Michigan

Maniteau Construction Co. is a family-owned general contractor serving Lansing, East Lansing, Grand Ledge, Greater Lansing, and surrounding Mid-Michigan communities. We've completed more than 60–70 projects, from smaller renovations to $1.5 million custom homes.

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.

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.

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.

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.

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.

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.
