Thinking of enhancing your space?

We’ve got you covered. KCS Building Group will help you love the home that you have.

Attached Garage

Garages are more than just a space to protect your vehicle; they can be versatile areas for storage, workshops, or recreational rooms. KCS Building Group specializes in attached garage additions that seamlessly integrate with your home's existing architecture. This addition enhances your property's visual appeal and provides the convenience of direct access to your home, making tasks like unloading groceries easier, especially in bad weather. The creation of garage additions is complex, requiring careful planning and execution to ensure structural integrity, functional utility, and aesthetic consistency with the main house. At KCS Building Group, we handle all aspects, from initial design consultations to securing permits and final construction. Whether you're looking for a simple one-car garage or a more complex structure with specialized storage or a second-story loft, we customize the project to meet your specific needs and lifestyle. Our team ensures 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 relish the outdoors without the hassle of bugs or bad weather. Screened porches offer the perfect blend of indoor and outdoor living. At KCS Building Group, we specialize in creating custom porch additions that are both practical and visually appealing. We collaborate with you to understand your lifestyle and design preferences, ensuring the new addition seamlessly integrates with your existing living space. The process of designing and constructing porch additions involves various factors such as material selection, structural considerations, and local zoning regulations. We manage these complexities, allowing you to envision a space for relaxation, entertainment, or alfresco dining—free from mosquitoes and sudden rain showers. Our team of experienced craftsmen meticulously attends to every detail, from the foundation to the final touches, to ensure your screened porch is a durable, comfortable, and stylish enhancement to your home. With KCS Building Group, your screened porch becomes more than just extra space; it becomes a sanctuary where you can enjoy the outdoors comfortably.

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 provides a budget-friendly option for protecting your vehicle from the weather while enhancing your property's functionality. More discreet than a full garage, carports can be quickly constructed and customized to blend with your home's style. Whether you need an independent structure or an addition to your current home, KCS Building Group designs carports that are both useful and aesthetically pleasing, ensuring they fit within your budget.


A driveway is the first thing visitors notice when they arrive at your home, and a well-crafted driveway can greatly boost your property's curb appeal. Whether you prefer a straightforward, functional asphalt driveway or a decorative stamped concrete design, we provide a variety of materials and finishes to meet your needs. At KCS Building Group, we manage every step from excavation to finalization, ensuring a long-lasting and appealing driveway that complements your home and stands the test of time.

Sidewalk replacement

Sidewalks enhance the aesthetic appeal of your property while improving safety and accessibility. Cracked or uneven sidewalks can be hazardous and detract from your home's appearance. KCS Building Group offers effective and durable solutions for replacing damaged sidewalks, ensuring they are safe and visually appealing.


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 an ageless addition that offers an elevated area for outdoor activities like barbecues and stargazing. At KCS Building Group, we construct custom wood decks using superior materials that resist weathering and wear. We collaborate closely with you to identify the best layout, materials, and finishes that fulfill your needs and complement your home's design. Whether you're aiming for a basic platform deck or an elaborate multi-level creation, our team guarantees your new wood deck is both functional and attractive, enhancing your outdoor living experience.
