Can the Owners Corporation object in its own right?
If so, could the EC resolve to engage a town planner to object on the OC's behalf?
Yes the Owners Corproation can and should object as a responsible body representing the views of the majority of residents. In fact, if you don't, the developers won't hesitate to point out that the OC of your building raised no objections.
And yes your OC can hire a town planner to formulate your objections in a language and format that planners will understand.
