What a Bathroom Addition Actually Costs
Adding a bathroom to your home is one of the most common home addition questions we hear, and the cost varies more than most people expect. Scope drives everything: a basic three-piece bathroom tucked into an unused corner of a finished basement costs far less than a full master bath addition on a second floor with new framing, plumbing rough-in, and exterior walls. The honest answer is that you won't get an accurate number without someone walking the job. What you can do right now is call Bob at (763) 331-2247 and describe what you're working with. Powerbuilt Construction holds MN General Contractor License #BC533891, and we pull permits on every addition we build.
Home addition construction covers a wide range of project types: a main-floor bedroom addition, a garage addition, a second story, a bump-out to expand a cramped kitchen, or a brand-new bathroom built into square footage that doesn't exist yet. Each of those projects has a different cost structure driven by foundation requirements, roof tie-in complexity, exterior finish matching, and how much existing structure we're connecting to. Additions at the smaller end, like a single bathroom rough-in on an existing slab, can be completed for a fraction of what a full two-story addition costs. In some cases you don't need to build out at all; reclaiming an attached garage as finished living space can add the room you're after without a new foundation. We won't quote you a number that doesn't fit your actual house. Every job is different, contact Powerbuilt Construction for an accurate estimate. You can also browse our home renovations page if your project blends addition work with broader remodel scope.
Addition Types We Build
We handle the full scope of residential addition construction, from single-room buildouts to full second-story additions.
Bathroom Additions
New bathroom construction in space that doesn't have one yet. We handle framing, plumbing rough-in coordination, electrical, tile, fixtures, and finish carpentry. Both above-grade and basement bath additions.
Room Additions
Main-floor bedroom, office, or living space additions attached to the existing structure. Includes foundation, exterior walls, roofline tie-in, insulation, and interior finish to match the home.
Second-Story Additions
Full second-floor additions built over an existing single-story home. Requires structural assessment of the existing foundation and first-floor framing before we scope the build.
Garage Additions
Attached or detached garage construction, including concrete work, framing, overhead doors, and interior finishing. Permitted through the local municipality on every project.
Kitchen Bump-Outs
Expanding a tight kitchen by pushing an exterior wall out 4 to 10 feet. Smaller footprint than a full addition, but the structural and exterior work is identical in scope.
Accessory Buildings
Standalone structures on the property for storage, workshop, or hobby space. Built to local code with proper permits, not as unpermitted outbuildings.
HOW IT WORKS
From Site Walk to Finished Addition
- 01
Site Assessment and Scope
Bob walks the property, reviews what you want to build, and identifies the structural, mechanical, and permitting requirements. No guessing. The scope gets locked before any number is discussed.
- 02
Permits and Foundation Work
We pull permits through your municipality before breaking ground. Foundation work comes first: footings, slab, or crawl space depending on what the addition requires and what code specifies.
- 03
Framing Through Finish
Framing, exterior sheathing, roofline tie-in, insulation, drywall, interior trim, and all finish work. We coordinate subcontractors for plumbing and electrical so you're not managing multiple crews.
