Custom Architectural Expansion and Precision Garage Builds

As your life evolves, your home should evolve alongside it. Families grow, remote work dynamics change, and hobbies demand dedicated square footage. Often, the neighborhood you love, the school district your children attend, and the roots you have planted make moving away an unappealing option. When your current layout begins to feel restrictive, structural expansion is the ideal solution. At Kevin Montondo General Construction (KMGC), we specialize in designing and building custom home additions that seamlessly integrate with your existing property, giving you the exact space you need while drastically increasing your equity.

Serving Peachtree City, Georgia, and the surrounding Fayette and Coweta county areas, our family-owned business brings more than thirty years of elite construction experience to every job site. We approach new construction and structural expansions with a level of care and precision that only decades of master carpentry can provide. Whether you are looking to add a luxurious primary wing, a multi-generational in-law suite, or highly functional detached garage builds, we handle the entire process with total professionalism. From the initial foundation pour to the final roof ridge, our team delivers structures engineered for safety, beauty, and lifelong durability.

Why Choose Structural Expansion Over Moving?

When space gets tight, many homeowners assume that buying a new house is the only option. However, in today’s real estate market, building custom home additions presents a far more practical, customizable, and financially sound alternative. Choosing to expand your footprint allows you to correct the exact layout flaws of your current house without sacrificing your ideal geographic location.

Furthermore, executing major structural expansions or detached garage builds allows you to design from a blank canvas. Instead of settling for someone else’s design choices, you collaborate directly with a high-end residential general contractor to tailor the layout, window placement, ceiling height, and lighting schemes to your daily routines. At KMGC, we analyze your property lines, local building codes, and structural load pathways to design an expansion that maximizes your usable land while maintaining a flawless architectural flow.

Room Additions

If you’re looking to expand your home with additional living space, our room addition solutions are the ideal addition to your personalized renovation services. A professionally designed room addition allows you to increase square footage, improve functionality, and enhance your home’s overall comfort and value without the need to relocate.

Our Approach to Room Additions

True craftsmanship in room additions comes from precise structural integration, proper permitting, and seamless blending with your existing home. Many addition projects fail due to poor foundation work, mismatched design, and improper tie-ins to existing systems. Our process ensures a cohesive, durable, and fully functional extension of your home:

Design & Planning Integration: We develop a custom layout that matches your home’s existing structure while meeting your space and lifestyle needs.
Foundation & Structural Build-Out: We construct a solid foundation and framing system engineered to safely support the new living space.
Exterior & Interior Finishing: We seamlessly match roofing, siding, flooring, and interior finishes so the addition blends naturally with the rest of your home.

By integrating a room addition into your property, we create a seamless expansion that enhances livability, increases property value, and provides the extra space your family needs.

Garage Additions

If you’re looking to add secure storage, workspace functionality, or extra vehicle protection, our garage addition solutions are the ideal addition to your personalized home improvement services. A professionally built garage addition increases property value, enhances convenience, and provides durable space tailored for parking, storage, or workshop use.

Our Approach to Garage Additions

True craftsmanship in garage construction comes from proper foundation work, structural engineering, and seamless integration with your existing home. Many garage projects fail due to poor drainage planning, weak framing, and lack of proper insulation or utility planning. Our process ensures a strong, functional, and long-lasting structure:

Site Preparation & Foundation Work: TWe prepare the build area and pour a reinforced concrete foundation designed to support long-term structural load and vehicle use.
Framing & Structural Construction: We build a durable framing system engineered for strength, stability, and proper alignment with your existing home.

A professionally designed sunroom creates a bright, relaxing space that blends indoor comfort with outdoor views, enhancing both livability and overall property value.

Our Approach to Sunroom Construction

True craftsmanship in sunroom construction comes from proper insulation, structural integration, and high-performance glass installation. Many sunrooms fail over time due to temperature control issues, water intrusion, and poor framing connections. Our process ensures a comfortable, energy-efficient, and long-lasting space:

Design & Structural Planning: We create a custom sunroom layout that complements your home’s architecture while maximizing natural light and usable space.
Foundation & Framing Installation: We construct a solid, properly engineered foundation and frame to support the structure and ensure long-term stability
Insulation, Sealing & Finishing: We properly insulate and seal the entire structure, then complete interior and exterior finishes for a comfortable, polished living space.

By integrating a sunroom into your home, we create a versatile extension that can be enjoyed year-round for relaxing, entertaining, or simply enjoying the outdoors from the comfort of inside.

Second Story Additions

If you’re looking to significantly expand your living space without increasing your home’s footprint, our second story addition solutions are the ideal addition to your personalized home improvement services. A professionally designed second story addition allows you to double usable square footage while enhancing functionality, layout flow, and overall property value.

Our Approach to Second Story Additions

True craftsmanship in second story construction comes from advanced structural engineering, careful load distribution, and seamless integration with the existing home. Many projects fail due to inadequate foundation support, poor framing transitions, and lack of proper system rerouting. Our process ensures a safe, stable, and fully integrated expansion:

Structural Evaluation & Engineering: We assess your home’s foundation and framing to ensure it can safely support a second-story addition, making necessary reinforcements where required.
Framing & Vertical Construction: We construct a fully engineered upper level designed for strength, stability, and long-term durability.
Exterior Integration & Finishing: We match roofing, siding, windows, and architectural details to create a seamless transition between the original structure and the new addition.

By integrating a second-story addition into your home, we deliver a high-impact transformation that maximizes space, enhances livability, and significantly increases overall property value.

 Trustindex verifies that the original source of the review is Google. Kevin and his entire crew are amazing to work with. We hired him to screen in our patio. Kevin listened to what we wanted but also gave some suggestions of different ways to complete the job. We ended up going with his solution as that was going to be the most cost effective way to complete the job! Not only do they do incredible work but they communicated with me through the entire process!!! When issues arise Kevin works through them and is not happy till you are. I would definitely recommend Kevin and his team and will use them again on future projects.

 Trustindex verifies that the original source of the review is Google. We had an exceptional experience working with Kevin Montondo and his team on our kitchen remodel. From start to finish, the entire project felt organized, intentional, and well managed. They did an amazing job staying on schedule, communicating clearly, and taking the time to explain things along the way so we always felt informed and comfortable with decisions.

What I appreciated most was Kevin’s adaptability. As our vision shifted and evolved throughout the project, he stayed solution-oriented, flexible, and collaborative instead of making changes feel difficult or frustrating. That mattered a lot to us. The final work product was exceptional — the craftsmanship, attention to detail, and overall execution truly exceeded expectations.

Their pricing was also very fair and regionally competitive for the level of quality and professionalism they delivered. On top of that, their crew was consistently respectful of our home and space throughout the remodel, which does not go unnoticed during a project of this scale.

we genuinely trusted Kevin throughout this process and really valued the way he leads his team and communicates with clients. We will absolutely be doing more projects with him in the future, and I would highly recommend Kevin and his team to anyone looking for quality work, integrity, and a contractor they can trust. :)

 Trustindex verifies that the original source of the review is Google. Kevin has done many jobs for me throughout the years. He installed new windows throughout the house, renovated master bath, guest bath, & kitchen. His team is professional & they do a thorough job. He also painted the interior when he did my master bath & kitchen. I trust them in my house when I’m not there. I have more future projects in mind & will not consider anyone else to do the work. I highly recommend Kevin. You won’t be disappointed!

 Trustindex verifies that the original source of the review is Google. KMGC replaced our deck with TimberTech for us between January and February 2026.  Chase was incredibly responsive and patient with us as we went through multiple iterations of what we wanted (expanding scope!)- even days before new concrete patio was poured, allowing to expand patio beyond original ask.  They were willing (and ultimately able) to reuse existing metal railings to help save money on the budget.  They kept us well informed of the process, what was happening when.  After the build was complete we noticed one board that was pulling up and not secured- they came out and took care of fixing it right away.
Very happy with our deck (with underdecking) and patio and have already called them to quote the next project!

 Trustindex verifies that the original source of the review is Google. Kevin, Chase & their team of dedicated, consummate professionals really do what they say! Honest, rightly priced, great local all-in-one home construction company !!

Chase & I priced out multiple different projects. He was very patient with me as my dynamic situation caused re-prioritization of work a few times.

Ultimately, they planned & finished my new roof, including a new metal accent roof over my wrap around front porch & new upstairs skylight window with ease & efficiency!

When I originally booked the project for just my bathroom skylight in the cold winter months of GA, they expertly asked me to wait for warmer weather to ensure proper sealant adhesion. They ordered & stored my window next to Kevin’s desk almost 4 months!! Sooo happy I waited! It’s all done & gorgeous now!!

 Trustindex verifies that the original source of the review is Google. Chase, Kevin and their whole crew really brought our imagination to life. From the covered patio addition, custom brick facing fireplace, stacking sliding door and even a fresh exterior paint job on the whole house to top it off. Was able to stay within budget and get it done just they we wanted. Would recommend them 10 out of 10 times.

 Trustindex verifies that the original source of the review is Google. Kevin Montondo knows homes in Peachtree City's established neighborhoods when it comes to renovations as well as how to modify or enhance any home.  He renovated my bathroom, giving tons of storage and a huge shower to a small space.  He knows color choice -- the paint color he recommended for our interior 10+ years ago still gets compliments - and he offers the best suggestions for the space, style and function of your home.  Let his company do your painting and you will never want to do it yourself again.
