Building on the Social Stair and Transit Oriented Area policies of the BC Government, what further policy interventions might help New Westminster develop more like the single lot redevelopment image, and less like the Land Assembly image?

Here's a lot in New Westminster. There is one building on each lot, home to one family each.

Here is a way that those same lots might be redeveloped. One lot at a time, so that the mix of owners and developers leads to a mix of styles.

Here's another way this street might be developed: one developer buys a multi-lot Land Assembly and builds a single building on the lot. There are many downsides to this approach.
