1. Kitchen door looks in white similar to bathroom door but with no louver.
2. Three lifts can reach to all floors under group control.
3. The floor lobby was not too bright at that time. Reddish brown tiles looks dark but if the lighting level is strong then it will be good la. Besides some wall tiles in ivy color can make a good contrast.
4. I did not go to 50/F becasue the sky was so polluted that I could not see anything further.
The main door is finished by dark brown formica with stainless steel ironmongery. Existing one looks better than the one in Show Flat. Anyway it doesn't look matching with the white doors. Overall the workmanship should be acceptable.
BTW the swing door in kitchen is a normal door swinging inwards.
