Bedrock Detroit is settling into its new downtown Detroit digs at 630 Woodward, a historic four-floor building once home to retailer Christopher Mabley.

The real estate development firm, part of the Detroit-based Quicken Loans Inc. family of companies, moved from One Campus Martius to its new headquarters in February to consolidate operations, said Jake Chidester, director of design for Bedrock.

Nearly 180 employees are stationed at the 39,000-square-foot headquarters, including its executives, Chidester said. Owner Dan Gilbert does not have an office there.

Bedrock bought the building, which is attached to its First National Building, in 2013 for an undisclosed price. It sold in 2000 for $1.2 million.

The only other tenant in the building is Bangkok Crossing restaurant, which is walled off from Bedrock's reception area on the first floor.

The development firm is the first tenant of the building's upper three floors since the 1970s, Chidester said.

From fluffy pillows lining a wide staircase under a glass roof, to a hidden, speakeasy-style bar on the second floor, the building's design is anything but traditional office style.

"Classically urban with an industrial edge," is how dPOP designer Bryce Gamper described it.

"We wanted a living room feel," he said, adding that the small soft-seating groupings encourage "small moments" between colleagues and impromptu meetings that dodge the awkwardness of cubicle conversations.

Each floor is decorated with work from local artists and adorned with items that are a nod to Detroit's history and future, such as a large Shinola clock and railings designed after the Model T, said Evans, the lead designer. The goal was to keep its interior true to its historic exterior while blending in a modern feel.

"We wanted it to be Detroit, without it being (overly) Detroit," he said.

The second floor features several "phone booths," or small private rooms where employees can get away from the open office environment. Nestled in the corner is a fully stocked bar, strictly limited to after-work hours and special engagements, Chidester said.

The general contractor of the build-out was Detroit-based Sachse Construction. The architect was Southfield-based Neumann/Smith while Detroit-based Kyle Evans Design took lead on design of the building, along with dPOP , a design firm in Quicken's portfolio.

Investment in the build-out was not disclosed.

As the company continues its pursuit of new tenants — nationally and even internationally, a spokeswoman said via email — it intends to make a statement with its new headquarters that Detroit is a great place to do business.

"Christopher Mabley saw Detroit as the perfect location for destination retail, and that vision lives on through Bedrock's work," she said.
