The neighbourhood is really only the three blocks (South Park to Queen excluding Park Victoria) plus half of the block south of Morris.

I personally have no problem with this. It's pretty obvious if you wander around in this part of the city that it is something special and deserves to be preserved. I would argue that this is true as well of South Street below Queen and of for example stretches of Inglis, Carlton, South Park, Jubilee.. etc. Brunswick was a bit of a stretch because it has no consistent, finely-scaled feel anymore, and in fact the new townhouses in that neighbourhood are inappropriately small and cheap. Brunswick and Gottingen should be considered inner-city infill areas like the southern parts of Barrington and Hollis. Yes, they have heritage buildings, but they also have apartment towers and commercial buildings.

As for limiting the possibility of infill, Halifax has tons of ugly and underdeveloped areas that can be built up before the few remaining attractive and coherent residential neighbourhoods are torn up.
