Custom Home Building Central Iowa
- Home Addition Builder
What Makes a Home Custom?
A custom home starts with your plan and your lot instead of a floor plan the builder repeats forty times. You choose the layout, the room count, the ceiling heights, and where the windows land. Nothing is locked before you say so.
Semi-custom sits in the middle. You start from an existing plan and change what matters to you, which costs less than drawing from scratch. See everything we build, or compare the two paths in our guide to semi-custom versus fully custom builders.
About Us
Since 2020, Busy Builders has completed 1,285+ construction and remodeling projects across Central Iowa. We build home additions for families who need more space and want it done right the first time.
Every addition we build is designed to match the existing home’s structure, style, and systems so it feels like it was always there.
Our Mission
Honest pricing, a clear written plan, and no surprise charges on every home addition project we take on.
We tell you what the project actually requires before a single permit is filed, and we do not upsell scope the addition doesn’t need.
Our Vision
We want to be the registered general contractor that homeowners in Des Moines, West Des Moines, Ankeny, Waukee, Johnston, and Grimes call first when the house isn’t big enough anymore.
- Frequently Asked Questions
Why Build Custom Instead of Buying?
The Plan Is Actually Yours
Room sizes, ceiling heights, window placement, and storage get designed around how you live, not around what sells fastest.
Budget Talk Comes First
We tell you what your number really buys before you spend anything on design. Honest math early beats a painful redraw later.
One Team, Start to Finish
The same people who priced it build it. No handoff between a sales office and a field crew who never met you.
Selections Without the Guesswork
Finish allowances go in writing so your estimate reflects the house you actually chose, not a generic builder-grade placeholder.
Iowa Specific From Day One
Frost line footings, radon rough-in, and the 2024 IRC are part of the plan from the start, not surprises found at inspection.
1,285+ Projects of Practice
Since 2020 across Central Iowa. We have already made the mistakes that cost first-time builders money.
- Home Additions Step By Step
How We Build Your Custom Home
PLAN AND BUDGET TOGETHER
We start with the number, not the drawing. Telling you upfront that a 2,800 square foot plan does not fit a $400,000 budget saves months. Once the plan and the budget agree, design work is worth paying for.
- Target budget set first
- Plan sized to the number
- No design work on a plan you cannot build
DESIGN AND SELECTIONS
Architectural design runs $3,000 to $8,000 for most custom plans. We work through finishes with you early, because selections drive far more of the final cost than square footage does.
- Plans drawn to your layout
- Finish allowances set in writing
- Selections locked before framing
PERMITS AND PLAN REVIEW
We pull the permit and manage plan review with your city or county. Some metro suburbs take six to twelve weeks to review a custom plan, and knowing that upfront keeps your expectations honest.
- Permit application filed
- Plan review corrections handled
- Inspection schedule mapped
FOUNDATION AND FRAMING
Excavation, footings below the 42 inch frost line, poured walls with waterproofing and drain tile, then framing. Framing usually runs four to eight weeks depending on the plan.
- Footings below frost line
- Foundation waterproofed and drained
- Framing squared and inspected
MECHANICALS AND ENCLOSURE
Plumbing, electrical, and HVAC rough-in, then insulation and drywall. This stretch typically runs six to ten weeks. Passive radon rough-in goes in now because it is cheap here and expensive later.
- Rough-ins inspected before cover
- Passive radon system stubbed in
- Insulation and air sealing verified
FINISHES AND WALKTHROUGH
Cabinets, counters, flooring, trim, and paint run eight to twelve weeks. We walk the house with you, build the punch list together, and finish it before you move in, not after.
- Selections installed as specified
- Punch list built with you
- Final inspection and occupancy

FAQs About Custom Home Building
How much does a custom home cost in Central Iowa?
Quality custom construction starts at about $150 per square foot. Mid-range finishes run $175 to $225, and higher end work runs $225 to $300 or more. A 2,000 to 2,500 square foot custom home commonly lands between $350,000 and $475,000. Your written estimate sets the real figure.
How long does it take to build a custom home?
Most Central Iowa custom homes take 8 to 14 months from permit approval to move-in. Design and plan review add time before that, and some metro suburbs take six to twelve weeks just to review plans. Weather during foundation and framing is the biggest schedule variable.
What is the difference between custom and semi-custom?
A fully custom home starts from a blank sheet and your lot. A semi-custom home starts from an existing plan and changes what matters to you. Semi-custom costs less because the design work is already done. Many families get what they actually wanted from semi-custom.
Do I need to own land before I start?
No, but it changes the sequence. If you already own a lot, we evaluate the site first because soil, slope, and utility distance drive real cost. If you do not, we can help you judge whether a parcel will build affordably before you buy it.
Should I budget a contingency?
Yes. Plan 10 to 15 percent above your build number. Site conditions, plan review corrections, and mid-build selection changes are the three things that most often move the total. A contingency you do not spend is money you keep.
Are you registered to build in Iowa?
Yes. Busy Builders holds Iowa contractor registration #C140184 through the Department of Inspections, Appeals, and Licensing. Iowa registers general contractors rather than licensing them. Electricians, plumbers, and HVAC technicians on our projects carry their own separate state licenses.
