Barrington Street in Halifax. Nothing major built on this block but there have been a lot of little changes over the years.
The far corner building on the foreground block doesn't look like much but it is an early concrete building from the 1910's and it is being renovated and expanded with two new upper floors. It might turn out to be great. The narrow 60's building across the street is good too, although it has lost a bit of its detailing and elegance over the decades.
