Ice Castle Fish Houses Logo

Based in Minnesota since 1993, Ice Castle has become the premier manufacturer of quality ice houses. Like every great story, this one also came from small beginnings. Back in 1993, AS&M operated out of what is locally known as Smith Addition. A small, concrete building housed surplus items for sale and produced sheds and doghouses. One day, in 1997 we were asked to build 10 sheds on wheels. They sold right away and the Ice Castle Fish house was born.


In the 20 years since then, Ice Castle has pioneered many new and innovative features that have shaped the wheel house industry. Adding AC units as well as water and wastewater holding tanks transformed our fish houses into an All-Season RV. In 2010 we received RVIA certification. Today, the demand for Ice Castles has grown our company from 8 employees up to 150 during peak demand. Providing an All-Season RV, equipped with the right materials to handle harsh weather conditions is a product we are proud to offer. We look forward to being a part of your next adventure, whether it’s a simple excursion to a local lake or a cross country trek!
