It is understood that the building will be constructed in Cyberjaya, replacing the party’s current headquarters in Jalan Raja Laut, Kuala Lumpur.

In a Facebook post showing an illustration of the building, Iskandar acknowledged that the design might not resemble that of conventional PAS buildings.

“But really, what are the defining features of a PAS building? Is it supposed to have minarets? Arches? Domes?” he asked.

“The question of what makes a building ‘PAS-style’ is perhaps similar to past debates about what constitutes ‘Islamic architecture’ or ‘Malaysian architecture’ – debates that took place in the 1980s and 1990s.

“To me, this complex is an opportunity for PAS to send a message to the world – that PAS is moving forward. The complex will be a ‘signature building’ symbolising PAS’s aspiration to lead the people and the nation towards becoming a developed country.”

The former Selangor executive councillor said PAS was asked what kind of design it had in mind during a discussion with the complex’s architect.

Iskandar said he instantly supported designs inspired by famed Iraqi-British architect Zaha Hadid, whose works include the aquatics centre used in the 2012 London Olympics.

Her other notable projects include the Italian National Museum of 21st Century Arts in Rome, the Heydar Aliyev Centre in Baku, the Rosenthal Center for Contemporary Art in Cincinnati and the Guangzhou Opera House in China.

“Eventually, this design emerged … But we’re still open to feedback,” he said.

“I know some ‘old-school’ professionals may disagree with this kind of design for a PAS building – that’s their right.

“But let’s move with the times and embrace current trends in sustainability and eco-friendly designs.”
