Room Additions
That Fit Your Life
Running out of space at home? At Bump Out Addition Des Moines, we build room additions that give older Des Moines homes the extra square footage families actually need — done right, on budget, and built to last.
Professional Room Additions in Des Moines
Our room addition services cover everything from master bedroom expansions to new family rooms, home offices, and in-law suites. We work on older Des Moines homes every day and know how to tie a new room into an existing structure properly — foundation, framing, roofline, and all.
We use both new and quality aftermarket materials — flooring, tiles, framing, and fixtures — so we can build something that fits your budget without cutting corners. Every room addition we build is finished to match your existing home and ready to use from day one.

Our 5-Step Room Addition Process
We begin by understanding your vision, needs, and budget — at no cost to you. We look at your home's layout and talk through the best way to add the space you need.
Together we create a plan that works with your existing home and walk you through material options — new and aftermarket flooring, tiles, and fixtures — to fit your budget and style.
Our team navigates all local Des Moines regulations and permits required for your room addition so the project starts the right way and stays on schedule.
We handle everything from demolition to final touches — foundation, framing, roofing, insulation, flooring, and fixtures — ensuring minimal disruption to your daily life.
Once the project is complete, we walk through every detail to ensure you are completely satisfied before we consider the job done.
Common Reasons Homeowners Choose a Room Addition
-
Space Constraints
Families outgrow their homes. A room addition gives you the extra bedroom, office, or living area you need without the cost and disruption of moving to a new house.
-
Aging Infrastructure
Older Des Moines homes often have leaking floors, outdated materials, and spaces that simply don't meet current needs. A room addition is the right time to fix what's aging while adding what's missing.
-
Life Changes
A new baby, a parent moving in, or switching to working from home can change your space needs fast. A room addition lets your home grow with your family instead of forcing a move.
-
Wear & Tear
An older room showing significant wear — damaged floors, poor insulation, outdated fixtures — may be worth expanding and rebuilding rather than patching piece by piece.
Repair, Replacement & Maintenance Options
Repairing Existing Structures
Before we build, we address existing problems — leaking floors, rotted framing, outdated insulation — that would undermine the new room if left alone. We fix what's there before we add what's new.
Replacing Old Features
Old flooring, fixtures, tiles, and windows can be replaced with energy-efficient alternatives as part of your room addition. Both new and quality aftermarket options are available to fit your budget.
Routine Maintenance
We advise on how to keep your new room addition in top condition year after year — protecting your investment through Iowa's seasonal extremes and keeping everything working the way it should.
"We needed a bedroom for my mother-in-law and had no idea where to start. Bump Out Addition Des Moines handled everything — permits, design, construction — and the result looks like it was always part of the house."
