We care about quality work done right the first time, so we self-perform and hire dependable partners. We care about supporting the communities we work in, so our time, resources and profits are donated without hesitation.

Off-Site Construction

Off-site construction is faster, safer, more regulated and requires less coordination efforts, resulting in more productivity and improved quality control.
Our new 85,000 square foot off-site construction facility maximizes our self-reliance and competitive advantage by improving each project’s quality, safety, schedule, and site logistics. All facets of a project can be constructed in our facility including bathroom pods, exam rooms, offices, electrical and data distribution rooms, and interior and exterior wall systems.

Our Portfolio

Whether restoring a faith-based structure to its former glory, or building a new specialty hospital downtown, the end result is always the highest standard in construction.

Boys & Girls Club – Duneland Club

The building expansion of the Boys and Girls Club in Porter County provided much-needed additional space and services to the children in the community. The 19,000 square foot expansion of the existing Club included a full-size gymnasium, a two-story rock-climbing wall, a new lobby, reception and concessions area, fitness studio, an education center, STEM lab, and a teen tech lounge with state-of-the art technology and equipment.

As a result of this renovation and expansion, active membership at the Duneland Boys & Girls Club increased from 474 in 2016 to 920 youth and teens in 2017. The average daily attendance skyrocketed by more than 110% going from 145 kids per day to more than 310 kids using the Club every day!
