The -01, -02, and -03 suites are the same size since they have the narrow L shape. The -04, however (at least that's what the agent told me and as shown in the first picture), have about 200 extra square feet. The -04 series basically has 2 extra hallway space that the other suites don't have. That makes the living area a lot bigger (the -04 series have the large L shape sofa where as the other suites have smaller sofas.) The bedroom is also bigger.
