Garage Addition Contractor in Greater Lansing

Expand your home without moving. We build custom garage additions in Lansing for parking, storage, workshops, home gyms, and more.

Expand your home without moving. We design and build custom garage additions as part of our home addition services in Lansing, East Lansing, Okemos, Haslett, and surrounding Mid-Michigan communities for parking, storage, workshops, and bonus space above the garage.


A garage addition should do more than add square footage. It should fit your home, function for the way you live, and hold up to Michigan’s weather, code requirements, and seasonal freeze-thaw conditions.

Types of Garage Additions We Build

Attached Garage Additions

An attached garage addition provides direct access to your home, which can be especially convenient during Michigan winters. The design also needs to account for how the new structure connects to the existing foundation, walls, roofline, and exterior materials.

Detached Garage Additions

A detached garage addition can provide more flexibility when the home's layout or property makes an attached expansion impractical. Depending on the design, it can provide space for vehicles, storage, workshops, hobbies, or other uses away from the main living areas.

Living Space Above the Garage

Building upward can add valuable square footage without taking up as much additional yard space. An addition above garage space can become a bedroom, home office, guest suite, bonus room, or other finished living area, provided the structure is designed to support the additional load.

Garage Addition Challenges We Solve for Homeowners

Making a New Garage Look Like It Belongs

The right siding, roofing, windows, trim, and architectural details help an attached garage addition blend naturally with the existing structure instead of looking like an afterthought.

Managing the Structural Complexity of a Garage Addition

Building onto your home affects more than the footprint of your property. We account for foundation requirements, load-bearing walls, roof connections, drainage, and the transition between new and existing structures before construction begins.

Getting More Space Without Losing Your Yard

When your home needs more parking, storage, or usable space, we help you evaluate the available property and design a layout that makes the most of your existing lot.

Planning for Michigan’s Freeze-Thaw Conditions

Garage additions need to withstand the same harsh conditions as the rest of your home. We design foundations, insulation, roofing, and exterior assemblies to account for Michigan winters, seasonal moisture, and the 42-inch frost line.

What's Included in a Garage Addition

A garage addition involves more than framing four walls and installing a garage door. The project requires coordinated planning, structural work, exterior construction, and finishing details to create a space that functions properly.

Planning, Design, and Permits

We start by reviewing your goals, property, and existing home. The design process accounts for the layout, size, entry points, exterior style, storage needs, and how the new garage will connect to the rest of the property as well as pull permits.

Foundation and Framing

The foundation and framing establish the structural foundation of the project. They must be designed to support the walls, roof, garage doors, storage needs, and any finished living space above the garage.

Roofing, Siding, and Exterior Details

We coordinate rooflines, siding, trim, windows, and other exterior details so the addition complements the existing home and creates a cohesive finished appearance.

Electrical, Insulation, and Interior Features

Depending on how you plan to use the space, your garage may require lighting, outlets, insulation, heating, cooling, and other mechanical features. These details become especially important when the garage will be used year-round or includes finished space above it.
