hi relaxman,
are you sure Eco summer charge around rm400 a month for maintenance?
I believe you already know the pros and cons about strata landed, so let's skip this topic here.
About the toilet, its actually all about ventilation. If the toilet with ventilation equip installed, it will definately to provide air circulation.
Even toilet with window, you still need one and it will suck all the bad air out from the toilet lots faster. Or, when the wind blow in the wrong direction, all bad smelly fresh air is an great negative impact too.
In Taiwan, there is many high-end condo also has no window for toilet but with ventilation fan installed. You know why? during the typhoon time and winter time you just can't open the window at all. so there is a reason for doing so.
It just in MY & SG is not too common (but available on commercial shopping malls and 5-star hotels too, but you just ignore it and said those are different), but doesn't means will not have one. Oh yes, depend on how powerful of those fans too, of coz. my 2 cents.
Besides, I am a Summer buyer too.
Let's dont off topic here, any other projects related topic, please go to respective thread instead.
