The leaning tower of Portland Avenue

Mike Gustafson walked onto the roof and pointed up at the majestic onion dome that has crowned the Bardwell-Ferrant house for more than a century.

"I just don't want this thing to fall down," said Gustafson, who bought the house in June.

He gestured toward an ominous bulge and crack in the elaborate woodwork. "See here, where it's buckling. It's crunching, somewhere in the ribs of it."

Indeed, one of the house's two towers is leaning, alarmingly, ­toward Portland Avenue. Built in 1883 and retrofitted in 1890 in Moorish Revival style with two towers, keyhole-shaped windows and spiraled columns, the Bardwell-Ferrant house is so distinctive that it resides on the National Register of Historic Places.

But 129 years of history have not always been kind to this landmark in the Phillips neighborhood of Minneapolis. Gustafson, 52, a painting contractor who has had his own ups and downs, has neither the money nor the skills to repair his ailing dome.

He's hoping the fortunes of the Bardwell-Ferrant house will soar once again when more people find out about its current predicament. After all, it has been rescued before.

The home's beginnings

In 1898, the house made way for an apartment building and was moved to its present location at 2500 Portland. Since then, its rounded porch, keyhole-shaped stained-glass windows and, most strikingly, two whimsically carved wooden towers with copper helmets have stood out among the ­solid but unremarkable homes around it.

As the neighborhood lost its allure, 2500 Portland became a rooming house. About the time of its 100th birthday, the house was vacant, a hole in its roof leaking onto hardwood floors, when a pair of real estate investors and old-home enthusiasts spotted it. They spent $160,000 to renovate the house, restoring such details as its original spiral posts, and turned it into four apartments.

The rescue brought the Bard­well-Ferrant house into the 21st century, but its troubles weren't over. The investors sold the house in 2001, and less than a decade later, a bank foreclosed on it. Thieves pried off three elaborate mantelpieces and carried them away, and damaged one of the few original stained-glass windows that remained as they tried in vain to steal it, too. They also ripped out the copper pipes from the furnace and baseboard radiators.

Meanwhile, a neighbor was going through his own tribulation.

A new owner moves in

In 2011, the bank repossessed Gustafson's house. But he found a new place just across the alley. He and his wife bought the Bardwell-­Ferrant house and moved in with their extended families.

He has started to remove partitions and make other changes to restore it to a single-family house, but aside from a good paint job, he's limited in what he can do. The scars where woodwork was torn out still pain him. All he has are black-and-white photographs of the old mantelpieces that he found on the Internet.

"It's almost like neglecting and abusing an old person, and then stealing their jewelry," Gustafson said. "I feel ­sorry for the house."

That sympathy extends to government and nonprofit advocates for historic preservation, but no one knows yet whether someone can ride to the rescue of the leaning ­tower.

Erin Hanafin Berg, a field representative for the Preservation Alliance of Minnesota, and Aaron Hanauer, a city planner who staffs the Minneapolis Heritage Preservation Commission, said they were interested in talking to Gustafson about his situation.

Hanauer said a number of nonprofits and neighborhood groups might help, but "there isn't any specific city program dedicated to help preserving local landmarks." The city used to give property tax relief to those who renovated old houses, but that program went away more than six years ago, he said.

If the tower becomes a safety hazard, however, city housing inspectors would get involved, Hanauer said.

Gustafson hopes it won't come to that.
