Detroit — The president of General Motors bought the grandiose Alfred J. Fisher mansion in Palmer Woods for $1.55 million, one of the highest prices ever paid for a Detroit residence.

The same property was put back on the market this summer after plans unraveled to turn it into a dormitory for addiction treatment patients.

The previous owner paid $1.6 million last summer but couldn’t overcome neighborhood and city opposition to open his house for recovering addicts.

City land records show that GM President Daniel Ammann and his wife, Pernilla Ammann, bought the 15-bedroom mansion on Balmoral Drive in the upscale historic neighborhood on July 31.

Palmer Woods sits between Highland Park and Ferndale and is still home to some of the city’s wealthiest professionals.

Although the sale price wasn’t recorded, a woman who identified herself Monday as a partner of the listing’s broker said the property sold for its $1,549,000 asking price.

The Fisher mansion dates to 1926, features an indoor swimming pool and was built for one of the brothers of the Fisher family in the auto body business. The family donated the house in 1968 to the University of Detroit Mercy, which later sold it to a private owner.
