The once-condemned office building at 1977 West River Road in Minneapolis will soon get a $7.3 million overhaul.

DC Group, a provider of uninterruptible power supply services, initially rehabbed the dilapidated building in the early 1990s when it moved into the space. Now it's completely redesigning the headquarters, adding 25,000 square feet of office/warehouse and a new 86 stall parking garage.

"Our business is growing, so is our team, and now it's time to grow our space," said Jon Frank, founder and CEO of DC Group. "This will be an intensive project, but DC Group has been here for 29 years. We moved in when the building was in rough shape then made it our home. This project makes sense for our company."

DC Group has seen robust growth in recent years. Since 2006, the company's revenue has gone from about $5 million to $28 million annually. It serves nearly 20 percent of the Fortune 500 and has a 95 percent contract renewal rate. In the same time period, DC Group grew from 41 employees to 140 employees. The Minneapolis Chamber of Commerce recently recognized DC Group with the 2014 Best in Business Award.

The company was considering other locations for its headquarters, including new suburban developments. But, after working with the city of Minneapolis to secure tax increment financing, receiving support from the Minnesota Department of Employment and Economic Development (DEED) in the form of employment grants, and getting help with environmental clean up from the state, DC Group decided to redevelop its existing building.

"Minneapolis is an innovative city that's a perfect place for companies like DC Group," said Minneapolis City Council President Barbara Johnson, who worked with the company to lay out a financing plan.

The expansion plans call for significant aesthetic upgrades to the site and streetscape through a bold curved design, expansive windows, modern wood and metal cladding, and a roof deck. On the inside, the renovated building will include long-term bicycle storage and locker rooms and facilities to encourage use of alternative transit.

"We're pleased that the company will remain in this community for years to come and will continue to contribute to our growth," noted Ward 5 Councilman Blong Yang.
