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.
