On a macro level, all these developments, overall, don't have good Shapes and Forms Feng Shui.

More importantly, it is because of the layout of the blocks or for landed properties the arrangement of individual homes:-

1. No. 33 Siglap Hill

Not the best overall Shapes and Forms in the way each home is aligned with each other.

2. The Sunnydale @ Serangoon Avenue 3

To some it may be their fort, but to others.. it symbolises high security "prison" - profile... i.e. poor circulation of qi within the centre area of the site...

Althought the plot of land is not "perfect"; much effort was made for favourable Shapes and Forms Feng Shui.
