I agree. Its a massing. Shows the sq-footage that is allowed per FAR.
Final design may be different, but will have the FAR and sq-footage indicated by the massing models.
I hope a crown and a spire is included. One of those cases where it would really be nice (if its designed well, this could very well eclipse 1600+ ft. Depending on which version is used. For all we know… 1700 + ft?
