Great Western Contracting has spent 30 years across Northeast Wyoming earning the kind of trust that only comes from doing the work right, telling the truth before the contract is signed, and standing behind every project long after the crew leaves the site.

Client Testimonial

“We looked at several builders before we found Jason. What stood out right away was that he listened and was completely upfront about what things would cost. He never pushed us toward anything we did not need. The home turned out better than we imagined, and our heating bills are a fraction of what we paid in our old house. We tell everyone we know.”

Building in Big Horn Means Getting the Details Right From the Start

Big Horn is not a subdivision. It is a community that has always attracted people who care about the land they are building on, and that shows in how properties here are planned and maintained. The polo fields. The horse properties stretching toward the mountains. The older homes with character that have stood through generations of Wyoming weather. The Bighorns rising just to the west, visible from nearly every west-facing window on every property in the area. This is not the kind of place where a generic plan dropped onto a lot does justice to what the land offers. As your ICF home builder, we start every project by understanding what the site offers and what it asks before any wall system or floor plan is discussed.


You may be building a forever home on land you have owned for years, relocating to Wyoming from another state and choosing Big Horn for exactly the kind of quiet privacy and mountain proximity it offers, or investing in a property you intend to pass down through the family. Whatever brought you here, the planning conversation is where the project gets set up to succeed or struggle. As a custom home builder, we help you connect your goals, your site, your budget, and your long-term vision before any design decision becomes expensive to change. That conversation is free. Getting the early decisions wrong is not.

  • ➡️ Read More

    Big Horn also attracts buyers who know what they want and have high expectations for the people they hire. Privacy matters here. So does craftsmanship. So does a builder who communicates clearly, shows up when they say they will, and does not surprise you with changes that were never discussed. We operate that way on every project in this community, and we bring that same standard to every project across Sheridan County.

LET'S GET STARTED

Custom Home Builder in Big Horn: Homes That Fit the Land and the Life

A custom home in Big Horn should feel like it was made for that specific piece of ground. The views, the orientation, the driveway approach, the outdoor living areas, the way the morning light moves through the main living space. These are not afterthoughts to sort out once the floor plan is drawn. They are the starting point. As a custom home builder, we plan the home around the site from the first conversation. Where the home should sit. Which direction it should face. How the garage connects to the house without blocking the best views. How the outdoor space works with the Wyoming seasons. Those decisions made early are what separate a home that feels right from one that merely looks right in a rendering.


For buyers building at a higher level, the details matter even more. Natural stone that echoes the geology of the Bighorns. Timber accents that fit the ranch heritage of the area. Wide covered porches designed for the afternoon light. Guest quarters that give visitors their own space without disconnecting from the main home. Great rooms that feel generous without feeling empty. As a luxury home builder, we bring a builder's eye to every one of those decisions, not to talk you into more square footage, but to make sure what you are building actually delivers the experience you have been imagining. The best custom homes at this level are the ones where the budget was spent on the right things.


If you are coming to Big Horn from out of state, the planning process has its own layer of complexity. You may be making significant decisions about a property you have visited but do not live near yet. You need a builder who communicates proactively, not reactively. Who sends updates before you have to ask. Who flags issues honestly instead of hoping they resolve themselves. As a luxury home builder, we manage that process the way a long-distance build deserves to be managed. Clear communication at every stage, no surprises when you arrive.

ICF Concrete Homes Built for Big Horn Comfort and Wyoming Conditions

A home in Big Horn needs to perform through Wyoming winters and feel genuinely comfortable through every season, not just the mild ones. The ICF wall system addresses that at the structural level. Continuous R-26 insulation with no thermal bridging. An airtight envelope that holds temperature overnight without the heating system running constantly. A minimum 4-hour fire resistance rating that matters in a region where wildfire risk has been rising. As a concrete home builder, we help you understand what those differences mean for daily life in the home before you choose a wall system. Specs tell part of the story. The lived experience of a home that stays quiet when the wind moves across the meadow tells the rest.


The exterior of an ICF concrete home can be anything you want it to be. Stone. Board and batten. Timber frame accents. Stucco with mountain modern lines. The wall system is entirely behind the finish, and the finish is entirely your decision. Inside, the home is framed and detailed exactly like any custom home. The difference shows up in the utility bills, the quiet, and the confidence that the building was engineered for this specific climate. As your ICF home builder, we bring the Nudura system to every project here with the supply chain advantage of working directly with Wyoming ICF in Ranchester. That means material availability and product knowledge that general contractors occasionally promising ICF cannot always match.


For buyers building at a higher price point in Big Horn, the long-term ownership picture shifts the upfront cost conversation significantly. A home that costs less to heat, requires less maintenance, and carries a fire-resistant wall assembly changes the math over twenty or thirty years of ownership. Being a concrete home builder, we help you run that comparison honestly before the plans are finalized. The goal is a building method that serves your land, your life, and your long-term investment, not just the lowest number at signing.

Post Frame Builder in Big Horn: Homes, Shops, and Ranch Structures

Post frame construction in Big Horn is not just for working structures. Some of the most comfortable and well-appointed homes on Sheridan County acreage are post frame builds, and the design flexibility of the system makes it a natural fit for properties where the home and the working buildings need to feel like they belong together. As an authorized Lester Buildings dealer and post frame builder, we configure every building to the specific snow loads, wind loads, and site conditions of your property. Whether the project is a primary residence, a shop, a stable, or a combination of all three, the engineering is specific to your land.


Horse properties in particular need buildings that are planned around how the animals and the people caring for them actually move through the space. A pole barn designed without that understanding creates daily frustrations that compound over years of use. As a pole barn builder, we ask about your operation before we ask about your square footage. How many horses. Where the hay goes. How the tack room connects to the stalls. Where the vet needs access. What the paddock layout asks of the building orientation. Those conversations happen before a layout is drawn.



A well-planned post frame structure on a Big Horn property also adds value to the land itself. Working buildings that are well-sited, properly engineered, and finished to a standard that matches the main home reflect the overall quality of the property. As an award winning post frame builder, we think about how the working structures relate to the home, to the driveway, and to the long-term plan for the property. A building that fits the land and the life is one you never regret building.

Which Building Method Is Right for Your Project?

Choosing the right construction method has real long-term consequences for safety, comfort, energy costs, and insurability on Big Horn area land. Wildfire risk in Sheridan County is higher than 92 percent of all U.S. counties according to the U.S. Forest Service, and the properties at the base of the Bighorns carry their own fire exposure from the foothills above. Winters are serious at this elevation. Wind moves across the open meadows without much to slow it. A home planned without those realities in mind starts at a disadvantage from day one. This comparison gives you the information to make the right choice for your Big Horn property.

Factor Standard Stick Frame ICF Concrete Home Lester Post Frame
Fire Resistance Approx. 45 minutes Minimum 4-hour rated wall, 6-inch concrete core Engineered metal and post system supports fire-conscious design
Wind Resistance Standard code loads Up to 250 mph (Nudura specification) Engineered for open spans and rural site conditions
Insulation Max R-19, thermal bridging through studs R-26+ continuous, no thermal bridging, airtight envelope Insulation packages available for finished and working spaces
Energy Performance Higher heating costs in cold climates 30 to 58 percent reduction in heating and cooling demand Efficient for large buildings when properly insulated
Sound STC 35 to 40, wind and exterior noise audible STC 50+, concrete mass reduces exterior noise significantly Varies by insulation and interior finish
Best Fit Standard residential builds Forever homes, fire-resistant retreats, energy-efficient custom homes Ranch shops, equipment buildings, stables, garages, barndominiums

A buyer building a forever home on a Big Horn area property has different priorities than a landowner who needs a practical working structure. A buyer focused on fire risk, thermal performance, and long-term comfort may find the ICF concrete wall system is the clearest answer for this foothill setting. A landowner who needs open-span working space may find a Lester post frame building is exactly right. Great Western Contracting helps you work through that comparison before any money is committed. If you are weighing options and want to know whether a luxury home builder is the right fit for your property, that conversation costs nothing.

At the Foot of the Bighorns. Built to That Standard

Big Horn is part of Sheridan County, and it is practically next door. We have worked across this county long enough to understand what makes Big Horn distinct from the rest of it. The older ranch families who have been here for generations. The newer buyers who chose Big Horn specifically for what it is not: not a suburb, not a development, not a compromise. The community has a standard, and the properties here reflect it. We plan every project in Big Horn around that standard.


The person leading that work is Jason Szewc brings thirty years of Wyoming construction experience to every project throughout Northeastern Wyoming and this region, and a Historic Society Award for Preservation that reflects the level of craft he holds the team to. In a community like Big Horn where standards are high and people talk to each other, that record matters. As a pole barn builder Big Horn serving Sheridan County, we hold every project here to that same standard. We bring that same level of accountability to every project here regardless of size.

Frequently Asked Questions About Building in Big Horn WY

See some common questions and answers below, or call us at 307-667-0672

  • How do you plan a home around Big Horn views without sacrificing comfort?

    The Bighorn Mountains visible to the west from nearly every property in Big Horn are one of the primary reasons people build here, and capturing those views well requires planning the home around them from the very first conversation. Where the home sits on the lot. Which rooms get the best sightlines. How the roof and wall heights work together to frame the view without creating a cold north-facing wall. As a custom home builder, we walk the property and assess the view corridors before a floor plan is drawn. A home that was designed without accounting for what the land offers can leave the best views to a room the family rarely uses. That is an expensive mistake to fix after the walls are up.


  • Does ICF construction make sense for a higher-end home in Big Horn?

    It makes more sense here than almost anywhere. The buyers who choose Big Horn are typically building for the long term and care deeply about comfort, quiet, and the way a home performs through Wyoming winters. An ICF concrete home delivers all three. The wall system creates a genuinely quiet interior. Wind across the meadow stays outside where it belongs. The continuous insulation holds temperature in a way standard framing cannot. As a concrete home builder Big Horn we see this resonate with higher-end buyers in particular because the performance benefits align with what they are already prioritizing. It is not a compromise between quality and durability. It is both at once.


  • How do you approach a luxury build on Big Horn land from a distance?

    Long-distance luxury builds require a level of communication discipline that not every contractor prioritizes. You should expect regular updates without having to request them. Decisions that need your input should be surfaced clearly and early, not presented as faits accomplis. Issues should be reported honestly rather than managed quietly and discovered later. As a luxury home builder Big Horn we treat long-distance clients with the same standard we would want if we were the ones building from a thousand miles away. The property is significant. The investment is significant. The communication should reflect that.

  • What should a working structure on a Big Horn horse property include?

    Horse properties in Big Horn have requirements that go beyond a standard agricultural building. Stall dimensions designed for the specific breeds. Tack rooms positioned for easy access from both the barn and the house. Hay storage that is accessible but separated from the living areas of the barn. Wash rack placement that considers drainage and convenience. As a post frame builder, we approach equestrian structures as functional buildings first. Every layout decision should make daily care easier, reduce wasted steps, and account for how the property will be used when the weather is at its worst, not just on a comfortable afternoon in September.

  • Can a pole barn near Big Horn be finished to match a higher-end home?

    Yes, and on Big Horn properties it often should be. A working structure that looks out of place next to a well-designed custom home undermines the overall feel of the property. As a pole barn builder Big Horn we help you think through exterior materials, roofline, door placement, and site orientation so the working buildings feel like they belong on the same property as the main home. That attention to how everything fits together is what separates a well-planned rural property from one where the buildings were added without a coherent vision.


  • What makes restoring an older Big Horn home different from a standard renovation?

    The difference is in what you are trying to protect. A renovation updates a space. A restoration preserves the character of a building while making it structurally sound and more livable. The older homes in Big Horn often have original materials, proportions, and details that simply cannot be replicated with modern production materials. As a historic home restoration contractor, we source materials carefully, work slowly through the parts that matter most, and make sure every decision during the project protects what makes the home worth saving. That requires patience, skill, and a genuine respect for what the original builders were doing. Not every contractor brings all three.
