Also known as Menara Biru (Blue Minaret) among the Tampines Residents. The Minaret stands at 10 stories high (130ft).
As the community in Tampines flourished, there was a rising need to upgrade the mosque.

During the upgrading period, all activities were carried out at a musolla beside the present site.
The mosque was officially opened by Madam President Halimah Yacob on 20 April 2019.
