Is this considered a okay floorplan ?

Good day to all,  may i know how do you classify such a floorplan? It doesnt fully resemble a gun shape floorplan though it looks alittle similar.  May i ask is this a terrible floorplan? As it seems everything is squarish and rectangular except that there are missing corners here and there. How to find the centrepoint of such floorplan? Does the centrepoint means inauspicious if it coincides in the empty part that is not part of the floorplan? Does it means the centrepoint is in the air?
Thank you master lee for sharing about floorplans.
