West Sumatra Grand Mosque (Masjid Raya Sumatera Barat) was designed by Rizal Muslimin, an architect from Bandung. He won the 2007 National Architectural Design Competition for a new mosque in West Sumatra held by the Government of West Sumatra Province. The competition had 323 national and international participants. The winning design proceeded to technical planning and the construction finally began in early 2008.
The architect explained that the mosque roof depicts a stretch of cloth used to carry Hajar al-Aswad (the Black Stone). When the four tribes of Quraysh in Mecca disagreed over who was entitled to return the Hajar al-Aswad to its position after the renovation of the Ka’bah, the Prophet Muhammad decided to lay the Black Stone on a piece of cloth so that it can be carried together by a representative from each tribe holding each corner of the cloth. When viewed from above, the mosque roof is square with spired roof in all four corners. This towering tall angle also gives visualization of the gonjong (spired) roof of Rumah Gadang (Big House, Minangkabau traditional house). Visualization of the roof of this gadang house is evident when viewed from the four sides of the building. Minang colors are also seen in the unique carvings of Minangkabau Songket and calligraphy on all four sides of the façades.

The interesting construction of the mosque is the roof. Vertical roof-load force is distributed to four tilted concrete columns of 47-meter high and two concrete slabs that bring together diagonal tilted concrete columns. The tilted column is driven into the ground to a depth of 21 m and supported by 24-point pile foundation with a diameter of 80 centimeters while the roof frame construction using steel pipes.
The mosque, located within a complex of 40,343 m2, was built with concrete and steel frame constructions. Consisting of 3 floors, this mosque can accommodate 20,000 worshippers, the ground floor can accommodate 15,000 worshippers and the second and third floors can accommodate 5,000 worshipers, respectively. The mosque is also designed as shelter and evacuation site situated on the second and third floor.
The main prayer hall, a spacious space serving as a place of worship, is on the second floor at a seven-meter elevation. The main hall, aside from being accessible from the inside through a staircase, is also accessible from the outside through a sloping ramp with an open terrace shape. With an area of 4,430 m2, the second floor can accommodate between 5,000-6,000 worshippers.
The main hall is supported by 631 piles, the pile cap has a diameter of 1.7-meter and a depth of 7.7-meter. While the third floor of the mosque is a U-shaped 1832-meters square mezzanine floor.

The structural system and the building construction have considered the geographical condition of West Sumatra which is located in the earthquake prone area. The mosque is built with strong structures and construction design, shock absorbers that help buildings resist earthquakes. Due to its close proximity to Padang Beach, in addition to its function as house of worship, it can also be tsunami evacuation shelter or site by utilizing the second and the third floors.

The Grand Mosque of West Sumatera was officially used on 7 February 2014 marked with the first Friday Prayer. Since then, the mosque has been opened to the public although some supporting facilities or buildings are still in progress.
Compared to the initial results of the design competition, some adjustments have been made, such as the roof diagonal lines, the minaret shape and location, and other supporting buildings plans. In June 2018, the mosque’s south minaret has been completed.
