Here's another project near downtown Dartmouth:
http://www.theloftsatgreenvale.com/
I believe it is approved but I'm not sure if the developers have started construction. The Greenvale School itself is from the 1910s and was designed by Andrew Cobb, a well-known local architect from that period. It is in rough shape but could be very attractive once restored.
