Just a quick one, was that Downpipe supposed to be there in the front of the entrance door ?
Yup it is meant to run down that side. It's even there at all the display homes and there was another instagrammer who had the sentosa build who was not happy with it but it had to be there. It should be painted as well so hopefully it will look better.
Ok that's bit strange design. To be honest this is the first design I have seen with DP inside side of the porch. I saw your drawings as well and it does mention DP in the porch but doesn't show any size. At least they should have painted it to match with wall colour.
On a different note, which smart lock you have selected for the main door ? Would you get someone to install it ?
