The mansion that was home to the Congdon family while Glensheen was built is being remodeled into luxury apartments. A news release from Heirloom Property Management announces the majestic Redstone Lofts will have “12 modern style loft apartments and a commercial space that will all be available for lease beginning early 2019.”

The interior of the historic structure at 1509-1511 E. Superior St. was heavily damaged by an arson fire in 2014.

Known as “Redstone,” the brownstone mansion was built in 1892 as the home of renowned Duluth architect Oliver G. Traphagen. It served as the Congdon family home from 1897 to 1908, and later was subdivided into apartments. Advertising executive Howard Klatzky bought Redstone in 1986 and it served as the office of HTK Marketing and Communications from 1987 to 2014. It is on the National Register of Historic Places.

“We are excited to be a part of this investment in our community,” Heirloom Property Management President Michael Schraepfer said in the news release. “This redevelopment restores and reimagines one of Duluth’s oldest and most iconic homes. This project provides needed new housing for Duluth and offers an exceptional opportunity to live in this storied historic property.”

The building is owned by Redstone House LLC of Independence, Minn., which paid $45,000 for the fire-damaged structure in 2016.

Carpenters are finishing work on the project and Heirloom Property Management has created a waiting list for those interested in living in the property. A 695-sq.-ft. single bedroom and bath apartment runs $995 per month.
