ROCHESTER | BYRON | KASSON | AUSTIN | ORONOCOÂ
Some homes don’t need a remodel. They need more room to live.
When the life inside your home outgrows the walls around it, a home addition is how you stay in the neighborhood you love and in a home that finally fits.
Types of Home Additions
Make your vision come alive with our design-build services.
Accessory Dwelling Units (ADU’s)
A private, self-contained living space on your property, whether that’s for aging parents, an adult child, long-term guests, or just keeping your options open down the road.
Four-Season Porches
Rochester winters can be harsh. Extend your outdoor living with a true four-season porch, properly insulated and built to be comfortable year-round.
Kitchen Expansions
Sometimes a renovation can only take a kitchen so far, and what you really need is more floor space. Pushing the footprint out opens up what you couldn’t get otherwise. A bigger island, a walk-in pantry, a better connection to the backyard.
Family Room Addition
More room to gather, more natural light and more space for the everyday moments. A layout change that reshapes how the whole main floor lives.
Bedroom & Primary Suite Addition
An extra bedroom for a growing family, or a primary suite that gives you the retreat your current floor plan never had room for.Â
Second Story Addition
When the lot can’t grow outward, the home can grow up. Your existing foundation and framing get evaluated first to make sure they can carry an entire new level.
A Simple Process for Custom Home Additions
1. Consultation
We start by listening. Your goals, your property, your budget, your timeline. It begins with a phone call to understand what you want and what’s driving the project, and we’ll talk honestly about feasibility, existing conditions, and what your land can support before anyone draws a line.
2. Discovery
We visit your home to measure, photograph, and document the space, then our designers get to work on 2–3 conceptual floor plans. You’ll see them come to life at our showroom, complete with 3D color renderings and initial material visuals, so you can react and we can refine. It’s a collaboration, not a presentation.
3. Project Development
Concepts become construction-ready plans. Finalized layouts and elevations, structural engineering, designer-approved material selections, permits, and a final proposal with precise pricing. When you sign, you know exactly what you’re building and exactly what it costs.
4. Remodel
We handle permits and a pre-construction meeting, then construction begins, sequenced and supervised by a dedicated project manager who makes daily site visits. From framing and structural work to finishes, you follow every step through daily logs and live scheduling in your client portal, right on your phone, and we walk the finished space together before we call it complete.
What to Consider When Planning a Home Addition
- Lot size and buildable area. How much room exists to grow, and in which directions?
- Setback requirements. Required distances from property lines, neighboring structures, and easements vary by zoning district and can quietly determine where an addition can and cannot go.
- Green space requirements. Many lots are limited to a maximum percentage of impervious or built coverage. An addition has to fit within that.
- Utilities. The location of buried lines, septic systems, and service connections can shape the footprint.
The Stier Approach to Adding on to an Existing Home
With over 16 years of experience, our home addition philosophy revolves around creating spaces that blend functionality with beauty. We strive to create inviting environments where living, gathering, and everyday moments come together. Each addition we design and build reflects our clients’ unique tastes and enhances their experience at home.
During your home addition, our expert Interior Designers will partner with you to identify the most impactful changes to enhance your daily life.
Why Design-Build matters for an addition:
- One point of contact, not several. You’re not relaying messages between an architect, a contractor, an engineer, and a designer. The same people handle your project from start to finish, so the details don’t fall through the cracks between companies.
- The design is built around your budget from day one. Our designers and builders sit at the same table. Real construction costs inform every design decision as it’s made. By the time you see drawings, you’re seeing something we know we can build at the investment level we’ve discussed.
- The result isn’t just efficiency. It’s clarity, confidence, and a finished addition that matches both the vision and the budget you started with.

FAQs About Building a Home Addition
How much does a home addition cost in Rochester, MN?
In the Rochester area, a professionally designed and built home addition typically runs about $450-$700 per square foot, depending on the room type, structural complexity, and finish level.
Do you handle all permits?
Permitting is handled entirely in-house and by vetted partners.
Can I build an ADU on my property in Rochester, MN?
It depends on your lot. Zoning district, lot size, setbacks, and green space requirements all factor in. Feasibility review is the first step of our process, so you’ll know what’s possible before investing in design.
How long does a home addition take?
Every addition moves through design, engineering, permitting, and construction and each phase depends on the project’s scope and complexity. During your consultation, we’ll map a realistic timeline for your specific addition, and once construction begins, you’ll follow progress against a live schedule in your client portal.
Can I live in my home during construction?
Your home stays your home. One of our advantages is that most of the work happens outside your existing walls. We install sealed zipper-wall barriers between the work zone and your living space to protect non-work areas from dust, and keep disruption contained. For larger, multi-room additions, we’ll give you an honest recommendation on whether moving out for a stretch would make the process less stressful.
What's the difference between hiring Stier and hiring an architect and contractor separately?
One team instead of two. With design and construction under one roof, your custom home addition is designed around your real budget, nothing is lost between parties, and one company is accountable for the entire result.
