Welcome to Next-Gen Buildings LLC, your trusted partner for construction and design services in Sullivan, Effingham, Pana, Taylorville, Paris, Shelbyville, and Assumption.

WHY CHOOSE US
When it comes to choosing a builder for you project, trust is everything. Too often, property owners face surprise costs, poor communication, or shortcuts that lead to long-term issues. At Next-Gen, we set ourselves apart by focusing on three principles: transparency, craftsmanship, and customer satisfaction!
Transparent Planning and Bidding
We believe surprises belong at birthdays, not in your construction budget. That’s why our bidding process is thorough, detailed, and fully explained upfront. You’ll always understand the scope, cost, and timeline of your project before we begin.
Craftsmanship You Can Count On
Every board, beam, and nail matters. We take pride in building with precision and care, ensuring the finished product not only looks incredible but performs as it should for years to come.
Customer-First Approach
Your satisfaction isn’t just a box we check; it’s the measure of our success. If you’re not happy, we’re not finished. Our team stays hands-on, available, and engaged until you are fully confident in the result.
Local Knowledge, Local Pride
Based in Sullivan, Illinois, we are proud to serve communities across Central Illinois. We understand local building codes, land conditions, and what families and farmers in our region truly need.
Choosing Next-Gen means choosing peace of mind, knowing your investment is in the hands of a team that values quality as much as you do.
ABOUT US
Our company was founded on a simple idea: building should be better — better homes, better barns, and better customer experiences. With more than 20 years of combined industry expertise, our team knows how to create structures that aren’t just beautiful but also functional, efficient, and built to stand the test of time. Whether you are planning a new family home, looking for a modern barndominium, or investing in durable farm buildings, you can rely on Next-Gen to deliver quality with integrity.
At Next-Gen Buildings, we take the stress out of construction by guiding you through every step of the process. From the first consultation to the final walkthrough, you’ll always know what to expect and who to turn to for answers. For us, construction is more than pouring concrete and raising walls — it’s about helping you feel confident, secure, and excited about your investment.
WHAT WE DO
A home is one of the most significant investments you’ll ever make, and it should reflect your lifestyle and goals. At Next-Gen, our custom home building services are designed to transform your ideas into reality. We don’t believe in cookie-cutter houses; instead, we focus on personalized designs tailored to your family’s needs.
From the first conversation, we’ll work with you to understand how you want to live in your new home. Do you dream of a spacious open floor plan? A kitchen designed for entertaining? A master suite that doubles as a retreat? Whatever your vision, our team will create detailed plans and bring them to life with craftsmanship and attention to detail.
Beyond aesthetics, we also prioritize energy efficiency, durable materials, and smart design choices that increase your home’s long-term value. With our design/build process, you’ll have one dedicated team managing everything — architectural planning, permitting, construction, and finishing. That means fewer delays, fewer miscommunications, and a smoother path to moving day.
Barndominiums combine the practicality of a barn with the comfort of a modern home, making them one of the most versatile building options available today. At Next-Gen Buildings, we specialize in custom barndominium design and construction that fits the unique needs of each client.
These structures are perfect for families who want wide open spaces, rural property owners who want a shop-house combination, or anyone looking for an affordable and durable home that doesn’t sacrifice style. Barndominiums can be finished with all the modern amenities of a traditional home — from luxury kitchens and spacious living rooms to custom bathrooms and bedrooms.
Our process ensures your barndominium is as unique as you are. We’ll help you design the layout, select the best materials, and integrate features that fit your lifestyle. Whether you want a simple, functional design or a luxurious country retreat, we’ll deliver a home that’s strong, stylish, and built for everyday living.
Farmers, equestrians, and property owners across Illinois trust us for pole barns and post frame buildings that are built to last. These structures are incredibly versatile and can be used for machinery storage, livestock housing, horse barns, workshops, or general farm use.
We know that agricultural and equestrian buildings face tough conditions, so we construct them with durability and longevity in mind. Our post frame construction methods allow for large, open interiors without unnecessary support beams, giving you more usable space at a lower cost.
Every pole barn we build is fully customized to the property it serves — from dimensions and roofing to ventilation and finishes.
When you choose Next-Gen for your pole barn or post frame building, you can rest assured it will be constructed to handle the weather, the workload, and the future needs of your operation.
Managing a construction project can be overwhelming when you have to juggle multiple contractors, architects, and builders. Our design/build services eliminate that stress by offering a streamlined approach. With one team handling the design and the construction, you’ll experience better communication, greater efficiency, and fewer delays.
Our design/build process includes everything from conceptual drawings and 3D renderings to material selection, budgeting, and construction management. Because our designers and builders work side by side, problems are solved faster, ideas flow more freely, and your project stays aligned with your budget and goals. This approach not only saves time but often reduces costs compared to the traditional design–bid–build method.
