Remember the corner where Dunbar Insurance used to be?
Behind the building stood one of the original (probably 1920's) houses. The house must have had a Dunbar address but when the commercial building was built in 1939, it had to change its orientation to 27th Avenue, and because the front porch of the house now faced the back of the commercial building, the porch had to become a side porch. The revised address for 27th Avenue of "3615" could be seen on the porch post. (But legally, it was still part of 4295 Dunbar Street.)
The 4200 block of Dunbar Street was demolished in April 2015, but this house stood for a little longer. Perhaps it was demolished in May 2015. Below is a view of the rear of the block's demolition, with a tiny slice of the house and its fence on the right. Note the large tree which could have been in the back yard of this house or the neighbouring house. In any case, the tree is gone.
Some of these buildings were pretty dilapidated!
