How We Can Help

Home Additions

A home addition gives you space to grow without needing to move. Whether you’re looking to add a bedroom, extend a kitchen, or build out a second living area, we can help you plan and build it from the ground up. Our team handles everything—from architectural design and permitting to framing, roofing, and finishing work. We tie the new space into your home’s structure so it feels natural, not tacked-on. Every addition is built with durability, comfort, and your daily routine in mind.

Garage Conversions

We help homeowners in Florissant convert garages into useful living space. That might mean creating a guest suite, gym, office, or fully insulated bonus room. We take care of the framing, electrical, insulation, HVAC integration, drywall, flooring, and finishes to make the space functional year-round. Garage conversions are a smart way to make better use of your square footage—and with the right design, they feel just as polished as the rest of your home.

Custom Kitchens

We remodel kitchens that are tailored to how you cook, gather, and move. Whether you're after a modern layout with slab cabinets and a quartz island or a traditional setup with warm wood tones and detailed trim, we can design and build the entire space. Our kitchen remodels include layout changes, cabinet design, custom storage, backsplash and flooring installation, and appliance integration. We focus on function and finish, giving you a kitchen that looks great and works better.

Bathroom Remodeling

A good bathroom remodel blends comfort, function, and design. We update everything from powder rooms to primary suites. That includes new vanities, tiled showers, bathtubs, lighting, plumbing, and ventilation. We can reconfigure the layout for better flow, build walk-in showers with niche storage, or help you select materials that feel elevated without being high-maintenance. Every bathroom we remodel is built to look good and stand up to daily use.

Basement Transformations

If your basement is unfinished or outdated, we can turn it into something better. That might be a family room, in-law suite, game area, or home theater. We handle moisture barriers, insulation, framing, drywall, lighting, flooring, and finish carpentry. Our basement remodels are designed to feel just as polished and comfortable as the main floors of your home. It's a great way to add usable space and long-term value without changing your home's footprint.

Sunrooms Into Living Space

Many older sunrooms aren’t built for year-round comfort. We convert them into fully insulated, climate-controlled rooms that blend into the rest of your house. This includes updating the foundation, walls, windows, HVAC access, and interior finishes. Whether you’re adding an office, playroom, or reading nook, we make the space feel permanent—not like an afterthought. You get the square footage you need and a finished room that adds both function and beauty.

Whole Home Renovations

Some homes need more than just a few updates. We take on full home renovations, from top-to-bottom layout redesigns to total interior upgrades. This includes everything from new flooring and drywall to updated kitchens, bathrooms, lighting, and finishes throughout the house. We also take on exterior updates, entryway expansions, and major system upgrades when needed. Whether you’ve just purchased a fixer-upper or want to make an older home work for modern life, we have the experience to do it right.

Excellence From Concept to Reality

Our design + build process keeps your remodeling project on track and under control from start to finish. You won’t have to juggle designers, architects, and contractors. Everything happens under one roof—design, architecture, layout planning, material selection, demolition, construction, and finishing work. That makes the process easier for you and keeps communication clear. It also helps us keep your project on time and within budget, with no surprises or delays. When one team handles it all, you get a smoother experience and a result that feels cohesive, complete, and true to your vision.
