Good post.
I generally agree, but, the wasteland of parking south of Main Street is a
tabula rasa where the city is able to create a distinctive skyline without impacting pre-existing residents or streetscapes. I think the city should be daring here. We need to create a skyline.
In the Avenir Centre precinct, mew development seems to be in the six storey range. I am comfortable with this. This section of the city is developing a walkable high density character.
Similarly, I envisage more human scale development between Main and St. George (with the odd tower), again to promote human scale and walkability.
BUT, south of Main, and, to a lesser extent in the extreme east end, I think height should be promoted to give the city a defining skyline. This is where the Three Sisters, the Gateway Towers, the Infinity Tower and the Ashford/Downing development are going anyway. This should continue to be promoted and encouraged.
