A flats plan is a plan attached to the cross lease title which shows the outline of the buildings on the land, allocates the building a “flat” or “area” number (e.g. Flat 1 or Area 1), and identifies the “exclusive use” area related to that flat or area.  The exclusive use area is for the use of that particular flat owner to the exclusion of all other flat owners and is marked with a letter. The flats plan also shows any “common area” which is an area shared by all or some of the owners of the fee simple land and is usually a driveway or accessway.
