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.
One of the biggest mistakes when choosing the right floor plan is that you forget to picture your own family cooking in the kitchen or you don't take into consideration how your bad back may not like going up 3 flights of stairs throughout the day. Assess your lifestyle before choosing a floor plan. Do you like a single story or multistory home? Do you prefer an open floor plan or are individual rooms with partitions better? Determine what you have become accustomed to in a comfortable home.
