4.3.4 Front Façade Step-backs
The podium created through a step-back above the building
base creates maximum a human-scaled heightstreetwall
and mitigates
the overall impacts of the building height on adjacent
streetscapes. The remainder 80% of of R.O.W. the building width envelope should 45
be carefully considered to allow for a minimum of 5 hours of
sunlight per day on boulevards across the street within the
Intensification Areas from March 21st (spring equinox) to
September 21st (Fall Equinox) to ensure pedestrian comfort
and encourage active use of the streetscapes.

used to ensure the 5 hour minimum is achieved, please refer to

Figure 32: Front Façade Step-backs
Example of building height responding to the angular plane.
45 o
a) A 45-degree angular plane should be applied at a height
equivalent to 80% of the width of the right-of-way. Above
this 80% height, building envelopes must step-back to
adhere to the angular plane.
b) On wider right-of-ways, a 45-degree angular plane applied
at 80% of the right-of-way width will result in a step-back
at the upper floors of the building. In this case, an additional
“pedestrian perception step-back” is recommended to
achieve a human-scaled building podium.
c) Step-backs should be a minimum of 1.5 metres. 3 metres is
recommended to ensure usable outdoor amenity spaces.
