WHO we are · What we do

In 1962, Harry and Aleide Bos immigrated to Wisconsin and started Bos Imp Co., a farm implement and importing business.  Today, their sons, Edwin and Harman, run Bos Design Builders and offer a complete line of building design and construction services to corporations and individuals throughout south-central Wisconsin.  With thousands of completed projects, through teamwork and client partnering, and with a strong sense of purpose and a commitment to quality and client satisfaction; Bos Design Builders is a valuable ally on any building project you may be considering.

The company combines the accessibility and support of a small, local firm with the strength and resources of nationally recognized building manufacturers. In 1978, Harry Bos helped found Cleary Buildings. Today, Cleary is one of the largest and most respected post frame building companies in the United States.  Likewise, the company’s long-standing relationships with local subcontractors and suppliers allows it to execute building projects on-time, on budget, and to a quality standard you will be proud of.


We recognize that a building means more to you and your future than simply bricks and mortar. It is equally important to OUR future that you are 100% satisfied.

Over half of our business comes from repeat clientele. Because design build allows us to work one-on-one with our clients from concept to completion we do achieve success together.
