The piece of land is designated for a mosque. When it will be built is entire up to the religion body of the government authority. Like any upmarket taman-taman there will always be a mosque as required by the law, TTDI, Bandar Utama, Mutiara Damansara all have 1 at least. There is no escape.

For more complete details kindly pm me for info 

are you Malaysians????

The azan is not a concern, but the haphazard parking by the Muslims performing the prayers can be frustrating to the road users. Especially during Ramadan and Friday prayers. Obviously we need to accept we are living in multi racial country however local authorities can design the access and mosque (and maybe parking building?). Or did Exsim consider the mosque into the masterplan (split access or majority of the development face away from mosque to minimise sound impact?)

From property buyers you need to consider this is can be concern especially your routine and whether this will outweigh the pro of the development.

Confirm build based on the facebook post?
Ia true they say deposit paid, but not enough funding yet. The plan for the masjid is also very very grand as per the post
