Waldeck was a brick house located at 166 Adam Street in Kitchener, Ontario. Designed by architect D. W. Gingerich, construction began in 1870. The building had a four-story tower and was likely the first home in Berlin to be centrally heated, which was possible due to steam pipes from the nearby tannery boiler room.

Philip Louis and Catherine Breithaupt moved into the home in 1871, and it was later the home of their son home of Albert Liborius Breithaupt and his family. The building was demolished in 1965 and the New Apostolic Church was later built on the site.
