Occupants | Photos & Maps | Sources

This two-storey house in the Armstrong’s Point area of Winnipeg was built in 1884-1885 for wholesale grocer Edmund Powis. It was significantly altered and enlarged to its present size by its next owner, hardware merchant William G. McMahon who occupied the house until his death in 1932. The next owner Joseph Wolinsky put concrete piles under the structure and changed it to a triplex. Today, the owners live in one of the suites and rent out the other two.





Edmund Powis (c1845-1930)


William George McMahon (1867-1932)


Emily Florence Woodley McMahon (1880-1946)
