Area of Improvement for HDB Layout

I don't understand why HDB comes up with this design where the toilet is at the side of main entrance door. I prefer the previous design where the toilet is located near the kitchen, away from main entrance door. Imagine if you don't clean the toilet and when you open the main door, you are greeted with unpleasant smell. It really bad design. I hope HDB will change the layout. I already feedback to HDB staff.
