If we take a look at the elevation it looks quite nice in 2D but I'm concerned about the hollows that the double storey bump outs create at the front of the house. I think it might be a bit dark and feel unwelcoming.
There is nothing like getting excited about architectural features that look beautiful on a 2D floor plan and feel even nicer when standing inside of the finished home. Details like expansive floor to ceiling windows, skylights and other architectural features could have an impact on heating and cooling your home when your energy bill arrives. While it may not be a concern now, think of green cost savings on your architectural features of your floor plan for future living too.
