Real estate developer Robert Glimcher, who lives in Squirrel Hill, has made an offer to buy the Morewood Heights mansion once occupied by Pittsburgh's Roman Catholic bishops, according to sources familiar with the property.

The mansion was listed for sale through Howard Hanna Realty in March because Bishop David Zubik decided to live instead in at St. Paul Seminary in East Carnegie.

The asking price is $2.5 million, but any buyer will need more money than that because the home's large kitchen and six bathrooms need to be updated.

"I know it's not sold," said the Rev. Ron Lengwin, a spokesman for the Diocese of Pittsburgh.

Howard "Hoddy" Hanna could not be reached for comment.

Built in 1910 by Herbert DePuy, owner of Pennsylvania Rubber Co., the mansion looks like a great English country house with its porte-cochere, baronial woodwork, silver and brass wall sconces, massive carved stone fireplaces, beamed ceilings, leaded French doors and hardwood floors. The wine cellar has room for at least 650 bottles. There's also a six-car garage.

The home sits on one acre. Its level back lawn features a large flagstone patio, many mature trees, a brick paver path laid in a herringbone pattern and enough room to throw an outdoor party for 500 people.

The mansion's assessed market value is $1.49 million on the Allegheny County's real estate Web site and its annual taxes are $44,067.

Mr. Glimcher and his wife, Megan, live on Dunmoyle Street, just around the corner from the Edwardian Tudor they have offered to buy.

Mr. Glimcher, whose company owns shopping centers, could not be reached for comment.

Mr. Glimcher is the son of shopping-center owner Herbert Glimcher, whose Glimcher Realty Trust building is in Columbus, Ohio.
