This thread is for Southwest Properties' proposed redevelopment of the Motherhouse lands in Rockingham.
Looks like this has the potential to be much better than an average suburban development. This will also be up to 1700 units on about 0.25 square kilometres, which works out to pretty high densities. There's another development of similar scale planned for a nearby wooded site off of Dunbrack, so this area could eventually have the population to sustain more mixed uses and better transit services.
An article and some conceptual renderings are here:

The eventual development may not look like this, but I hope this sort of design becomes more common. Given that a large percentage of suburban development in Halifax is already multi-unit (often with some underground parking), there isn't much of a reason why this sort of environment can't be built. You could take the existing buildings along an area like Parkland Drive, Regency Park, or Mount Royale and cluster them around smaller scale commercial buildings to create a dramatically better neighbourhood.
