An-Nur Mosque was the first mosque built in Woodlands. It is a 5-storey, blue-tiled, fully concrete structure with one of the highest minarets in Singapore. Intially designed by HDB architect Tony Tan Keng Joo, Masjid An-Nur is a prominent landmark in Woodlands with its 55-metre-high minaret. The building is often referred to as the “Blue Mosque of Singapore” due to its sky-blue exterior walls. Within the prayer hall, there is a mimbar (pulpit) with batik-like patterns and a golden dome, which catches and reflects light, alluding to the mosque’s name. Between 2011 and 2013, the mosque underwent major upgrading by ARC studio including the creation of a contiguous floor level on the first storey and the design of a simple roof over the existing blocks. Also a brand new façade gives the mosque a refreshed identity with better circulation and improved functionality. A simple Islamic geometry was used to unify various elements of the mosque.
