not to cari gaduh or anything.... what you mean "not sure what developer thinking".....
u means they should change from large window to smaller window?
or the should not build anything facing the west?

anyway- this issue is common in property. when ever possible, landed developer these day will have north-south orientation
condo a bit hard right, since all 4 side need to build something.

why can you use tint with high infra rejection?
it doesn't need to be chrome in color. many good brand has something of high visibility ( say 50% or so) with 80% + heat rejection.
It wont eliminate fully la, but add with black out curtain- certainly will help a lot.

Wall still remain warm, but at least not making the whole house like oven

Well.... if during initial sales, more units to choose from, as long as careful, then can get something that matches all the criteria.
inclusive the view ( i got friend which the window over look a shopping mall top, cooling towers and other vents), further from refuse chamber, away from lift etc

if sub-sales... hard to find anything that meet most the criteria. yes, risk lower, but if the unit is ideal- not so easy to reach you.
need to spend lot of time and effort. And more-ever, if ideal then the price will sure be higher at sub-sale.

well... have to balance ba
not all people got 3 years. may be new baby coming out. or kids going to start school etc.
so not all have the luxury to hunt and wait

Also even sub-sale, we cant rule out all risk.
eg- night mare neighbour, new taman development causing main road congested, etc
