below: Aug.30, 2010 - as seen at the right rear, behind where the three-storey brick wall of #131-133 had stood, there was a single-story addition which stretched back towards the firehall-looking Riverview building.
The next building still standing, with its west-wall now exposed, is #135 Colborne Street. [The stairwell and painted room outlines seen on the brick wall, of course, are (or rather, were) part of the inside east-side wall of #131-133 Colborne!]
above: Aug.30, 2010 - the roof of the single-storey addition (consisting of the mid-rear section of #131-133) had just been torn down several seconds ago, revealing for the first time this view from Colborne St. of the north-side of the square-topped tower of the old Riverside Automotive building on Water St. (in the center-right distance)
The wall of #135 is at the far left
below: Aug.30, 2010 - looking from the walkway, the mid-rear of #131-133 is being demolished. The firehall-looking old Riverview Automotive building with the tower, sits right behind this addition. Hard to tell whether this mid-rear section had any levels beneath it, going down the slope.
above: Aug.30, 2010 - looking from a little farther south along the walkway, it is clear that between the mid-rear addition and the old Riverview Automotive building at the right, the brick walls of the two buildings were separate, as seen closer below:
below: the brick over the gable of the Riverview structure (where it meets the mid-rear building) was laid in an odd manner - not horizontally, but rather at an angle, following the slope of the gable.
above: at the upper right, the Colborne-street-grade mid-rear section of #131-133 has now been removed, right up to the gable of the Riverview building, revealing a door-way which led from the (Colborne street-level) mid-section into the (Water St. fourth-storey!) gable of the Riverview building, as seen below:
