The Raja Haji Fi Sabilillah Mosque is designed to cater the growing population of Cyberjaya. Cyberjaya was initiated and founded by Malaysia's fourth Prime Minister, Tun Dr. Mahathir Mohamad in 1997. The township was envisaged as the Silicon Valley of Malaysia to accommodate the rise of Information Technology and the Knowledge economy, better known as the K-Economy. 7,000 acres of plantation land were acquired by the government for the purpose-built township of the future. It was planned to be completed in 2020 with a daytime population of approximately 210,000 people.

In 2013, it is only 15 years old and has a current daytime population of 52,000 people. It is currently only 40 percent developed and it is now estimated that the township will be completed within the next 10 to 15 years. It is also expected that by 2016, the daytime population will grow to approximately 64,000 people.

The main approach in designing this mosque, while following the GBI standards to Gold, is to ensure that the mosque is designed according to the standards that will make the mosque a truly sustainable mosque so that it will become a true model for the building of future mosques in Malaysia. The goal or original design intent of the mosque is to design the mosque’s main ‘Prayer Hall’ to be air conditioned for two hours during Friday prayers and during prayers for special events based on the Islamic Calendar. During other hours of the day and night, it is expected that the use of fans and ventilators would be sufficient. The Mosque is designed and planned to have an average daytime temperature of 26 degrees Celsius. We hope to achieve this target.

This will not only save energy and related running costs, but it will also maximise the use materials that are recyclable and will eventually help protect our environment. It is an opportunity for us to re-look and re-think the design of mosques in today's environmental concerns and awareness so that other architects may later build from our approach.

The purpose of this mosque is not only a place for prayers but also a place that revolves around the needs according to Islamic events, festivals and ceremonies. Like other similar Mosques in Malaysia, it is designed to accommodate a small dining and food preparation area for events like the Akad Nikah, the learning of the Quran, Hadith, Fardu Ain, Usrah, Kenduri Doa Selamat, Mandi Jenazah, Qurban and so on.
