Hi Master, yes, I would try to do the umbrella test recommended. I have also attached the photos of the master bedroom, common bedroom and living room which could show the gap between buildings for your reference.

Thanks Master for your reply. The MSCP roof is landscaped but mostly hardscape. From time to time I could feel the wind because I usually will open the window wide to ventilate my unit. Is this now not a good idea? I would like to add that I’m not putting up curtains. Hence should I be putting something else to circumvent this?

Dear Master, Would like to seek your opinion if the unit marked in black is affected by Tian Zhan Sha. Not familiar with these but seems like when I stand from bedrooms/ living room, the slit is quite prominent. Thank you.
