Project Location and Big-Picture Goals
This custom project was located in the community of Seneca, Missouri, for a homeowner who needed more functional space inside and out. The goals included building a detached garage, expanding the home with a new addition, and creating comfortable, customized interior spaces like a walk‑in closet and bathroom. The result showcases what E.L. Marshall Construction does best: custom renovations, home additions, and thoughtful new construction tailored to each family.
Building a Flood‑Safe Detached Garage and Driveway
Because the property sits in a flood zone, our team first had to bring in and compact additional dirt to raise the concrete pad to the required elevation so it would meet local code and help protect the new detached garage. This step is not just a box‑checking exercise; it directly affects the long‑term durability of the structure and the safety of anything stored inside. By taking the time to build up the pad correctly, we set the foundation—literally—for a garage and driveway that can stand up to the environment.
The concrete work included the pad for the new garage and the driveway leading up to the new addition for smooth daily access and better drainage. Proper grading, formwork, and control joints help reduce cracking and pooling, which is essential in a flood‑prone area. When you review detached garage photos from projects like this, you see clean lines, consistent finishes, and connections that look intentional because they were planned that way from the start.
Custom Interior: Bathroom and Walk‑in Closet
Inside, the project featured significant custom work in the bathroom and walk‑in closet areas. Instead of a basic bathroom remodel, the homeowner received a tailored layout that makes better use of the available space and supports daily routines with improved storage and flow. Details like fixture placement, lighting, and ventilation matter in a bathroom, and a design‑build contractor can coordinate all those decisions so they work together.
The walk‑in closet was also designed around the homeowner’s needs rather than a one‑size‑fits‑all layout. Custom shelving, hanging space, and traffic paths turn what could have been “leftover” square footage into a highly functional dressing and storage area. These types of custom home renovations add comfort and resale value while keeping the footprint aligned with the overall addition and garage project.
3D Model vs. Final Build and Porch Roofing Decisions
This Seneca project is a good example of how real‑world construction often evolves beyond the original 3D model. We use 3D design tools to plan out client remodels and additions. However, the homeowner chose to increase the size as the project progressed, which naturally added cost and required field adjustments. Our team kept open communication about those changes to ensure there were no surprises, turning potential pain points into collaborative decisions instead.
The backyard porch cover is another area where practical building drove smart choices. Because the patio cover pitch was lower than 3/12, standard roofing materials were not appropriate for long‑term performance, so a metal roofing system was selected. A low‑slope metal roof sheds water more reliably at that pitch, offers excellent durability, and, in this case, creates a clean, modern look that ties the porch into the existing structure. Choosing the right roofing material for a porch addition is not just aesthetic; it is a key part of protecting the structure and everything beneath it.
How this project met the homeowner’s needs—and how E.L. Marshall can help you
The homeowner needed:
- A detached garage for secure, dry storage and parking
- A code‑compliant, flood‑aware foundation for the additions
- More comfortable living space with a custom bathroom and walk‑in closet
- A backyard porch cover that could handle a low slope and still look great
By integrating site work, structural concrete, framing, roofing, and detailed interior finishes, E.L. Marshall Construction delivered a cohesive solution that meets all of those needs. The project also demonstrates how we handle change orders—like increasing the addition’s size—through clear, ongoing communication. If you are planning a custom renovation or a full home addition, E.L. Marshall Construction can guide you from 3D home design to finished new construction.
