The property owner is listed as “Amdev (Beamish) Limited Partnership” in the cover letter and the ownership contact is an email with @amdevproperty.com. I'm guessing it's Amdev.
"Triage Development Corp c/o Craig Hunter" is the agent for the application, and it is routine for the planner to be the agent. Why Craig isn't using the Hunter+Associates' corporation as the agent, I'm not sure.. Also not sure why Brook McIlroy is writing the planning application here.
Right you are. I misread the form. I stand corrected.
