About ThornHaüs Construction
At ThornHaüs Construction, we're a full-service residential contractor based in the Hudson Valley, specializing in custom homes, excavation, site work, and residential construction projects throughout Ulster, Greene, and the surrounding Hudson Valley communities.
Founded by lifelong friends and Saugerties natives Mitchell Thornton and Casey Backhaus, we partner with homeowners to bring projects to life, from the earliest stages of site preparation through the final phases of construction.
Why ThornHaus
Choosing the right contractor is about more than finding someone who can build. It's about finding a team that understands your property, communicates throughout the process, and approaches every project with the same level of care they would their own.
As Hudson Valley natives, we've spent our lives working in and around the communities we now serve. We understand the unique characteristics of building throughout the region, from rocky terrain and varying soil conditions to drainage challenges, local building requirements, and the expectations of homeowners throughout our neighborhoods.
Because we handle everything from excavation and grading to foundations, custom homes, garages, hardscapes, and full property development, we're able to oversee projects from start to finish while maintaining quality, communication, and accountability every step of the way.
Every property presents different opportunities and challenges, which is why we don't believe in one-size-fits-all solutions. We take the time to understand each site and build a plan that's tailored to the property and the homeowner's goals.

Our Approach
Construction is about more than the finished product, it's about every decision made along the way.
Proper planning, quality site work, and attention to detail during the early stages of a project create the foundation for everything that follows. That's why we stay hands-on throughout the process, ensuring every phase is completed with the same level of care and craftsmanship.
Whether it's a small site project or a full custom home, our goal is simple: deliver quality work that's built to last.
