Our History
Rich Arndorfer's homebuilding journey began at the age of 12, roofing alongside his grandfather and quickly advancing into custom home framing—many of them complex, rafter-framed lakefront homes that required technical mastery and precision from the start. His entrepreneurial drive, disciplined work ethic, and dedication to building at the highest level shaped more than twenty years of success in high-end residential construction.
Pat Hietpas advanced his career through extensive experience in construction planning, architectural coordination, land evaluation, and estimating, giving him a strong foundation in how homes are thoughtfully prepared, designed, and budgeted before construction begins. Pat grew up in northeast Wisconsin, working alongside his father in the family’s custom home-building business, where he learned the building trades firsthand and developed the strong work ethic that continues to shape his approach today. His background in residential construction, combined with a detail-minded approach, provides an essential balance to Rich’s field-driven craftsmanship and helps ensure each project advances efficiently and in alignment with the overall construction plan.
Rich and Pat’s longstanding professional relationship, shared values, and mutual commitment to excellence in luxury homebuilding ultimately led to the formation of Arndorfer Custom Homes. Together, they united their strengths—master craftsmanship and detailed pre-construction planning—to create a company built on integrity and an uncompromising standard of quality.
