A major historic preservation and housing project has reached its first milestone in Detroit's Cass Park neighborhood. Olympia Development of Michigan and Cinnaire Solutions celebrated the opening of the first phase of Henry Street Apartments on October 8, 2026.

The development is restoring seven historic buildings along Henry Street near Little Caesars Arena. The first phase includes residential buildings Bretton Hall at 439 Henry Street and The Claridge at 459 Henry Street, along with Ralston Commons at 447 Henry Street.

Ralston Commons, formerly a bowling alley, has been converted into a resident amenity and community center. Developers say residents are already living in Bretton Hall and The Claridge, bringing activity back to a historic block.

The broader plan calls for 170 renovated apartments across six residential buildings, with a seventh building serving as a community hub. The property's official website describes a mix of studio and one-bedroom units and shared amenities.

According to development reporting, 49 percent of the planned apartments are intended to be offered at affordable rates to households earning between 30 and 60 percent of area median income. That does not mean every unit is affordable or that all phases are already available.

The project's location places residents near downtown entertainment and other destinations. It also illustrates how restoring existing buildings can be paired with housing construction and neighborhood reinvestment.

Historic rehabilitation presents different challenges from building on an empty lot. Developers must balance preservation, building systems and modern residential needs while managing construction across multiple properties.

The first-phase ribbon cutting should not be confused with full completion. The property website lists additional buildings for future leasing, including dates in 2027, and those schedules could change.

The central questions for residents include the actual availability of income-restricted apartments, leasing requirements and the pace of the remaining work. Prospective tenants should consult the property's leasing office for current terms rather than relying on general project descriptions.
