Since Pug has kindly provided you with the information you wanted, let me add some info you need.
Before doing any applying, spend at least a month actually playing on the server, put yourself out there. Fly around the creative hub and its surrounding plots to get an idea what's "architect worthy" so you won't get disappointed in the case your eventual application gets denied.
Are you sure you can build at the level you see around the server? Do you have the dedication to finish projects? Can you imagine yourself building even in a months time?
Good luck.
