What is Your Remodeling Goal?
Expand Your Living Space
If your home is starting to feel tight, an addition may be the perfect next step. We design and build additions that blend naturally with your existing home—no awkward seams or mismatched finishes. Whether you want to add a primary suite, expand your living room, or create a new home office, we handle design, permitting, construction, and finishing from beginning to end.
Convert the Garage
Garage conversions are a smart way to make use of underutilized space. Whether you want a bonus room, in-law suite, gym, or private workspace, we’ll help you make it happen. Our team handles insulation, HVAC, electrical, drywall, and finish work so that the converted garage feels just like the rest of your home, only even more useful.
Renovate a Sunroom
Many homes in O’Fallon have sunrooms that don’t get much use. We can convert yours into a fully insulated, climate-controlled space that works year-round. This might include foundation upgrades, HVAC connections, electrical work, drywall, flooring, and new windows. It’s a great way to gain square footage without changing the footprint of your home.
Open the Floorplan
Removing a wall can transform how your home feels. We evaluate your space and rework the layout to create better flow, more natural light, and easier movement from room to room. Whether you're opening up a kitchen, connecting a dining area, or just making your home feel less segmented, we can make it happen.
Build a Dream Kitchen
We design and build kitchens around the way you cook, entertain, and gather. That means reworking the layout, designing custom cabinets, upgrading lighting and flooring, and installing high-performance appliances. Whether your vision is sleek and modern or warm and classic, we’ll help you get there, on time and within budget.
Uplifting Bathrooms
A well-designed bathroom should feel clean, comfortable, and easy to use. We remodel bathrooms with thoughtful layouts, custom tile work, updated vanities, new plumbing fixtures, and lighting that works for real life. Whether you're improving a small hall bath or building out a luxurious primary suite, we deliver practical elegance.
Other Renovation Goals
From full gut renovations to detailed interior upgrades, we’re equipped to handle just about any remodeling need. That includes full-floor updates, fireplace redesigns, mudroom additions, custom millwork, and more. If you have a space that isn’t working the way it should, we’ll work with you to reimagine and rebuild it.
Design + Build Excellence
At 5stone, we handle every phase of the remodel under one roof. Our process starts with design and architectural planning, where we help shape your ideas into a buildable plan. From there, we manage material selections, layout decisions, permitting, demolition, construction, and finishing. Every part of your project is coordinated by one team. That keeps communication simple, timelines realistic, and budgets in check. You don’t have to juggle different contractors or wonder who’s handling what. We take responsibility for the entire process so you can focus on the excitement of seeing your space come to life.

Every project is different, but in each one, we pay close attention to the details that separate good from great.
