Ultimate Construction Inc is your trusted partner for innovative building solutions in Dane County and beyond, specializing in SIPs construction, shop houses (shouses), and barndominiums. Our experienced team of construction professionals is committed to delivering high-performance structures that are energy-efficient, durable, and built to last.
We focus on projects that blend function with flexibility—whether you’re looking to create a custom barndominium, a shop house that combines living and workspace, or a structure that benefits from the superior insulation and strength of Structural Insulated Panels (SIPs). At Ultimate Construction Inc, we treat every project like it’s our own—delivering exceptional quality, clear communication, and results you can rely on.
EPS Structural Insulated Panels (SIPs)
SIPs are engineered panels used to construct walls, ceilings, and floors as a replacement for traditional framing lumber and insulation. They are easy to install, have higher insulating properties, and can lead to fewer drafts and a decrease in operating costs.
SIP usage reduces energy bills as much as 50 to 60 percent. Plus, structural insulated panels are extremely airtight and make it easier to control indoor air quality and heating, ventilation, and A/C systems.
Interior Comfort
People spend 90% of their time indoors — it’s essential that your environment remain safe and pollutant-free.
SIP homes offer superior air quality control, as the tight building envelope prevents contaminants and allergens from entering through incoming air. Controlling ventilation also filters out impurities and dehumidifies incoming air to prevent mold growth.
Exterior Style
Because an EPS home is built with Structural Insulated Panels, it offers plenty of options for exterior finishes. You can choose traditional wood or vinyl siding—or brick and stone. Exterior finishings not only add a decorative touch to your new home but also protect it from the elements over its lifetime.
Shouse Construction
Shed + House = Shouse!
For residential buildings, our post-frame and SIPs structures combine unmatched performance and value. Other building types cannot match Ultimate Construction ‘Shouses’ custom design—nor will they last as long or perform as well in extreme weather conditions.
Environmental Practices
At Ultimate Construction, We Believe in Building Green in Order to Preserve the Earth’s Natural Resources
We use superior products such as Structural Insulated Panel Systems (SIPS) to ensure that our homes and commercial spaces are energy-efficient and more comfortable. Our innovative designs and building practices help preserve the environment and protect our building sites by leaving nature preserves and wildlife habitats undisturbed.
