DETROIT, MI Construction on a Dan Gilbert-led development of 410 apartments and for-sale units in Detroit, Michigan's, Brush Park is expected to begin.

The plan for the City Modern development was first announced a year and a half ago at an expected cost of $70 million for 337 units. But the project has grown in size to 107 for-sale units and 303 rental units at a cost of more than $100 million, Steve Rosenthal, Principal of Gilbert's Bedrock LLC, said during a ceremony commemorating the start of construction.

A group called Brush Park Development Partners LLC won a request-for-proposal process last year to develop the 8.4-acre site.

The development is expected to include 24 buildings total, with 54 units being deemed affordable units for low-income seniors making 60 percent of the area median income.

The $65 million, The Scott at Brush Park by Birmingham, Michigan, -based Broder & Sachse Real Estate Services Inc. and Southfield, Michigan, -based Woodborn Partners LLC, is expected to be complete next month.

Detroit-based Sachse Construction LLC is the general contractor.

Five different architecture firms worked on the City Modern project: Detroit-based Hamilton Anderson Associates LLC; Grosse Pointe Park-based Christian Hurttienne Architects; Studio Dwell out of Chicago; Merge Architects out of Boston; and Lorcan O'Herlihy Architects out of Los Angeles.

Detroit-based civil engineering firm Giffels-Webster also worked on the project. Southfield-based Neumann/Smith Architecture is the project architect while Broder & Sachse is the lead developer and responsible for leasing and property management. Southfield-based Woodborn Partners LLC is the project's other developer. Detroit-based Bedrock LLC is responsible for leasing the retail space to tenants.
