Popular home additions for St. Louis living
Homeowners in St. Louis often seek functional spaces that improve daily living and boost property value. Our most popular additions include expanded kitchens for better flow and entertaining, additional bedrooms for growing families, sunrooms that invite natural light year-round, and full in-law suites for multi-generational living. We also handle bump-outs to enlarge bathrooms or living rooms without a full-scale addition.
These additions offer practical benefits: a larger kitchen creates a more enjoyable space for cooking and gathering; additional bedrooms or suites provide families with flexibility and privacy; sunrooms and living space expansions make homes feel more open and comfortable. A well-built addition can also significantly increase your home's resale value and overall appeal. At Kohlfeld Contracting LLC, we focus on building additions that look like they were always there.

Our commitment to seamless home integration
What distinguishes Kohlfeld Contracting LLC is our dedication to building additions that appear to have always been part of your home. We meticulously match rooflines, integrate seamlessly with existing structures, and ensure that siding, trim, and interior finishes are clean and uniform. Our customers consistently praise our clear communication and detailed scopes of work, which eliminate surprises.
We keep you informed throughout the project and never cut corners. You will work directly with an experienced contractor, not a sales team, ensuring an efficient and accountable process. Our goal is simple: to deliver a professional addition that adds real, long-term value to your St. Louis home.

Transforming homes in Valley Park
One of our most memorable projects involved a significant home addition in Valley Park, where we expanded the property by approximately 1,000 square feet. This included a 500-square-foot expansion of the main living area and an additional 500 square feet below, completely revitalizing the home's layout. We opened up the kitchen and living room to create a modern open floor plan and installed a brand new kitchen.
The project also featured cutting a new door into the foundation for a basement workshop, constructing a new composite deck, a full roof replacement, new Hardie siding, and new gutters to ensure a cohesive finish. The seamless integration made it look as if the addition had always been there, providing the homeowners with a much more functional layout, significantly increased living space, and enhanced property value.
