About This Home

1517 Altenau

A rare find in Cosmopolis — a full acre of privacy within city limits. 1517 Altenau offers space, comfort, and versatility with 4 bedrooms, a well-appointed kitchen with tile countertops and stainless-steel appliances, and an oversized dining room built for entertaining. Bonus living areas provide flexible spaces to relax or create your own getaway. Three lower-level bedrooms offer quiet separation and naturally cool temperatures. Outside, multi-level decks set the stage for summer BBQs and gatherings. The two additional parcels make this a truly a unique find.
