As a trusted home addition contractor Genesee County MI homeowners have relied on since 1959, we build additions that look and feel like they have always been part of the home.

We proudly serve homeowners throughout Flushing, Grand Blanc, Davison, Clio, Burton, and surrounding communities across Genesee County.

Seamless Home Additions & Room Expansions in Genesee County

A home addition should solve problems, not create new ones. Maybe your kitchen feels cramped. Maybe your family has outgrown the current layout. Maybe you need an in-law suite for a parent or adult child. Whatever the reason, Crannie Construction builds practical additions that improve how your home works every day.


As a leading home addition contractor Genesee County MI residents trust, we build additions that match the style and structure of your existing home. Rooflines, siding, flooring transitions, and interior flow all matter. A poorly planned addition stands out for the wrong reasons. We make sure the new space feels connected to the rest of your house.


Our team also helps homeowners plan projects that combine additions with outdoor improvements like deck additions. Coordinating both projects together can save time and help create a more functional living space overall.


Whether you need extra bedrooms, a larger family room, or space for multi-generational living, we provide straightforward guidance from the first meeting to the final walkthrough.


Common Reasons Homeowners Build Additions


  • Growing families that need more bedrooms or living space
  • Aging parents moving into the home
  • Expanding kitchens and dining areas
  • Creating dedicated home office space
  • Increasing overall square footage and real estate value
  • Avoiding the cost and stress of moving


Many homeowners are surprised by how much a well-designed addition can improve daily life. In many cases, staying and expanding makes more sense financially than buying a larger home elsewhere in Genesee County.

Types of Home Additions We Build

Every home and family is different. We build a wide range of additions throughout Genesee County based on your space, budget, and goals.


Room Additions


Need extra living space without moving? A room addition contractor can expand your home with a new bedroom, family room, office, or dining area that blends with your current layout.


We carefully plan each addition to match the existing structure, rooflines, and overall flow of your home.


Second-Story Additions


A second story addition Michigan homeowners choose often makes sense when lot size limits building outward. These projects add major square footage while preserving yard space.


Our team manages everything from structural planning to construction coordination to help the new level feel like part of the original home.


In-Law Suites


In-law suites provide privacy and independence for extended family members while keeping loved ones close to home.
These additions can include private entrances, bathrooms, kitchenettes, and accessible layouts designed around your family’s needs.


Kitchen Bump-Outs


A kitchen bump-out can dramatically improve traffic flow, storage, and functionality without requiring a full-scale addition footprint.


Many homeowners use this extra space to create larger islands, additional cabinetry, or more open dining areas.


Sunrooms


Sunrooms create bright, comfortable spaces that bring in natural light and provide extra room for relaxing or entertaining.


We build sunrooms designed to handle Michigan weather while creating a seamless transition between indoor and outdoor living.


Attached Garage Additions


Attached garages improve convenience, storage, and weather protection while adding useful square footage to the property.
These projects can also include workshop areas, overhead storage, or direct access into the home for added functionality.


As a trusted home addition contractor Genesee County MI homeowners rely on, we help clients compare options and choose the addition that best fits their property and long-term plans.

Proven Results: Home Addition Projects by Crannie Construction


I hired this company to do a shower remodel that included expanding the shower. The owner, Josh, did this job himself. The tile work looks beautiful and the grout lines are so precise. The quality of workmanship could not have been any better. I also used this company a few years ago to put up a privacy fence around my back yard. Again, the workmanship was excellent. I highly recommend Allison Contracting.


Susan Jackson


I have had them out twice now, to side my house and then my garage. They are very professional and they do outstanding work. They are also helpful when making a decision you are not sure about. Their cost is very reasonable compared to other well known companies I had called. They also give free estimates. I would highly recommend them for your next siding project.

  • Can I build a home addition on my lot?

    In most cases, yes, but lot-specific factors like setbacks, easements, and zoning classification affect what is possible and how large an addition can be. We review these factors during the design consultation process. If your project also involves outdoor living space improvements, our team can coordinate with our deck building services to plan both projects together.

  • How do home additions affect real estate value?

    Well-built additions often increase real estate value, especially in Genesee County where additional square footage matters to buyers. The return varies depending on the project type, but second-story additions and in-law suites are often strong long-term investments. The most important factor is making sure the addition matches the style and quality of the original home.

  • Does Crannie Construction offer custom home construction services?
