Brian Bosgraaf, owner of Dwelltech Solutions, was brought up in a family real estate and home development business. In 1985, Brian and his father formed Bosgraaf Homes, which planned home developments in West Michigan.

In 2000, hoping to combine his passion for the lakeshore with his talent and expertise in home building, Brian formed his own home design company, Cottage Home. Since then, Cottage Home has successfully designed and built more than 50 custom homes along the shoreline of Southwest Michigan. Cottage Home is an active member of Green Built Michigan, and utilizes green building practices.

In 2008, Brian recognized the need for a home energy audit service with the growing emphasis on reducing fossil fuels and energy sources, and working with homes on the lakeshore enduring extreme seasons. He took it one step further by offering recommendations and repairing issues uncovered in the audit for greater comfort, lower utility bills and increased real estate value. Dwelltech Solutions was born.

Brian is well known as a leader in the home building industry, having been involved with the Home Building Association on a local, state and national level.

Steve Kloosterhouse began his career in residential construction 25 years ago to pay his way through college. Though his focus in college was education, Steve remained interested in home building. His choice to remain in this field allows him to use his college education training when teaching homeowners about building science and how to make their homes more energy efficient.

In the early 90's Steve started working for Bosgraaf Builders as a customer service technician. It was during these years Steve found his new passion: problem solving. Problem solving often requires looking past the obvious to find the real solution, so having a working knowledge of houses from hands-on experience proved to be extremely useful in servicing new homes. All of this experience has evolved into Steve knowing how to make today's homes more energy efficient.

Most recently, Steve's interests have focused green and sustainable building practices. He was one of the first to become an NAHB Certified Green Professional in Michigan and has also helped administer the LEED certification of five homes for Cottage Home, one of which is LEED Platinum certified.

Steve is also a licensed builder in the state of Michigan.

John Kuiper, Audit Technician, has spent the past 30 years helping people with housing. His diverse career path is highlighted by his 11 years with Habitat for Humanity of Kent County, but ranges from Condominium Construction Manager to Community Organizer. John's journey has been marked by a continued commitment to energy efficiency since the '80's when he was teaching homeowners how to insulate their attics while building a passive solar addition to his own home.

John spent 7 years working for a community tool, paint and insulation program that assisted low income homeowners and for the Council of Neighborhood Associations, where he helped Grand Rapids neighborhood groups with planning, fundraising and housing issues. When John was hired as the Executive Director of Habitat, he was their first full time employee. The group relied on volunteers to build, and John wouldn’t ask a volunteer or future homeowner to do anything he wouldn’t try himself. 11 years later, Habitat volunteers were building 15 houses a year, and he had done every phase of construction right with them.

John worked for RDI Development for a couple years, where he managed the construction of 200 townhouses. He has also worked 6 years for Standale Lumber, where he was in charge of Green Building training for employees and customers.

In 2003, John saw his first blower door test with an infrared camera. It was surprising where the leaks were; it was obvious that traditional construction was not good enough; and it was clear that we could do better with attention to detail. He returned to Habitat briefly, and helped with 30 LEED for Homes Silver and Gold Certifications while monitoring the continuous improvement of their energy performance.

John holds a Bachelor of Science from Calvin College, is a licensed builder, a LEED AP and a certified HERS technician.

Recognizing increased efficiency as an important step towards building a sustainable future, he is excited to help make a difference with people’s homes. He says, “Sustainability isn’t about having to cut back, you can make home improvements that not only save money and the environment, but also make your home healthy and comfortable”.
