Schwans Construction
More Space. More Comfort. More Value for Your Home.
Whether you’re adding a new bedroom, expanding your kitchen, building an extra bathroom, or constructing a garage, our contractor team delivers home additions with a strong focus on safety, aesthetics, and functionality.
Every addition is meticulously planned to integrate with the existing structure, preserving visual harmony, structural stability, and energy efficiency.
Full Home Addition
A large-scale expansion that adds significant square footage to the existing footprint. Examples: new primary suite, expanded living areas, multi-room extensions.
Second-Story Addition
Construction of an entirely new level above the existing home. Commonly used for ranch-style homes to double square footage without expanding the footprint.
Garage Addition
Construction of an attached or detached garage, customized to your property and needs.
In-Law Suite / Accessory Dwelling Unit (ADU)
A self-contained living unit added to the property—attached, detached, or built above a garage. Includes a bedroom, bathroom, kitchenette, and private entrance.
Bump-Out Addition
A small extension of an existing room, ideal for increasing space without a full addition.
Deck Addition
Exterior platform additions with railings and stairs. Available in wood, composite, or PVC materials.

FAQ
You have questions, we have answers.
Is it safe to add onto my existing home?
Yes. Before moving forward, our team works with licensed engineers to assess your home’s structure and ensure the addition can be safely and properly integrated.
Will construction disrupt our daily routine?
Some disruption is expected during construction, but we take careful steps to minimize impact. We communicate clearly, maintain a clean job site, and plan work phases to reduce inconvenience as much as possible.
How long does a typical home addition take?
Timelines vary depending on the size, complexity, and scope of the addition, as well as permitting and inspections. Once we evaluate your project, we provide a realistic and detailed schedule.
Can we live in the home during construction?
In most cases, yes. We plan the work to allow homeowners to remain in the house whenever it’s safe and feasible to do so.
Do you handle permits and inspections?
Yes. We take care of all required permits and coordinate inspections with local authorities to ensure everything meets code.
How do you ensure the addition matches the existing home?
We carefully match architectural style, materials, finishes, and structural details so the addition blends seamlessly with your existing home, creating a cohesive and natural result.
