Attached Garage

Garages offer more than just a place to protect your vehicle; they can serve as versatile spaces that meet a range of needs from additional storage to workshops and even recreational rooms. When it comes to attached garages, KCS Building Group specializes in garage additions that are seamlessly integrated into the existing architecture of your home. This type of addition not only enhances the visual appeal of your property but also offers the convenience of direct access to your home, making tasks like unloading groceries easier, especially in inclement weather. The process of creating garage additions is intricate, requiring careful planning and execution to ensure structural integrity, functional utility, and aesthetic harmony with the main house. At KCS Building Group, we handle all aspects, from the initial design consultations to securing the necessary permits and the final construction. Whether you're looking for a simple one-car garage or a more complex structure that includes specialized storage or even a second-story loft, we customize the project to align with your specific needs and lifestyle. Our team ensures that the attached garage is not just an add-on, but a valuable, integrated extension of your home.

Screen Porch

Transforming your patio or deck into a screened porch allows you to enjoy the outdoors without the inconvenience of bugs or adverse weather conditions. Screened porches bring the best of both worlds by bridging the indoor and outdoor spaces of your home. At KCS Building Group, we create custom porch additions that are not only functional but also aesthetically pleasing. We work closely with you to understand your lifestyle and design preferences, ensuring that the new addition becomes a natural extension of your existing living space. The design and construction process for porch additions involves multiple factors including material selection, structural considerations, and even local zoning regulations. We handle all these complexities so you can focus on envisioning the space where you'll soon relax, entertain, or dine alfresco—without worrying about mosquitos or sudden rain showers. Our team of skilled craftsmen pays meticulous attention to every detail, from the foundational elements to the final finishes, to ensure your screened porch is a durable, comfortable, and stylish addition to your home. With KCS Building Group, your new screened porch becomes more than just an added space; it becomes a haven where you can enjoy the outdoors in the comfort of your home.

Concrete Patio

If you love outdoor gatherings or just enjoy a peaceful evening outside, a concrete patio is an excellent addition to your home. At KCS Building Group, we create beautiful, durable patios that seamlessly integrate with your existing outdoor space. With a variety of designs and finishes, we customize your patio to be an authentic extension of your home. This not only gives you additional functional space for entertainment and relaxation but also adds value to your property. Whether you envision a simple slab or an elaborate outdoor living area, our team ensures that your new concrete patio meets your functional needs while complementing your home’s aesthetics.


A carport is a cost-effective solution for protecting your vehicle from the elements while adding a functional feature to your property. Designed to be less intrusive than a full-fledged garage, carports can be quickly constructed and customized to match the aesthetics of your home. Whether you need a standalone structure or an extension of your current home, KCS Building Group crafts carports that are both functional and visually pleasing, all while staying within your budget.


Driveways are the first thing people see when they pull up to your home, and a well-designed driveway can significantly improve your property's curb appeal. Whether you're interested in a simple, functional asphalt driveway or a decorative stamped concrete design, we offer a range of materials and finishes to suit your needs. At KCS Building Group, we handle everything from excavation to completion, ensuring a durable and attractive driveway that enhances your home and lasts for years.

Sidewalk replacement

Sidewalks not only add aesthetic value to your property but also make it safer and more accessible. If you have a cracked or uneven sidewalk, it can pose a risk for trips and falls, as well as reduce your property's visual appeal. KCS Building Group can replace a damaged sidewalk if the condition of your existing sidewalk is damaged or unsafe with an effective and durable solution that also adds to the attractiveness of your home.


Sunrooms are a beautiful way to bring natural light into your home and extend your living space. They offer a perfect setting for relaxation, entertainment, or even a home office. KCS Building Group specializes in designing and building sunrooms that are tailored to your specific needs and stylistic preferences. We focus on energy-efficient materials and construction techniques, ensuring that your sunroom can be enjoyed in all seasons while keeping utility costs down. From traditional to contemporary designs, we make sure your sunroom becomes a cherished part of your home.

Wood Decks

Wood decks are a timeless addition that provide an elevated space for outdoor activities, from barbecues to stargazing. At KCS Building Group, we craft custom wood decks using high-quality materials that withstand the elements and time. We work closely with you to determine the best layout, materials, and finishes that meet your needs and complement your home's architecture. Whether you're looking for a simple platform deck or a multi-level masterpiece, our team ensures that your new wood deck is both functional and beautiful, enhancing your outdoor living experience.
