Due to the soft river bank, a deep foundation was required, To construct a stable foundation, 15-foot (4.6 m) of rocks and sand were entwined with wire mesh and topped by five feet of concrete. Five million fired bricks raised the foundation another 21.5-foot (6.6 m). These bricks were then topped by three more feet of concrete to form the main support under the monument.
On 2 July 2001, the first sculpted stone was laid.The team of eight sadhus watched over stone work as well as the research on carvings on Indian craftsmanship from between eighth and twelfth century. This research was done at various sites such as Angkor Wat, as well as Jodhpur, Jagannath Puri, Konark, and other temples in South India.
Over 6,000 tons of pink sandstone came from Rajasthan, workshop sites were set up around places within the state. Amongst the carvers were local farmers and fifteen hundred tribal women who had suffered from a drought and received economic gain due to this work. Every night, over one hundred trucks were sent to Akshardham, where four thousand workers and volunteers operated on the construction site.
Akshardham was inagurated on 6 November 2005 by Pramukh Swami Maharaj and ceremoniously dedicated to the nation by the President of India, Dr. A.P.J. Abdul Kalam. The Prime Minister, Manmohan Singh, and the Leader of the Opposition in the Indian Parliament, Lal Krishna Advani, with the presence of 25,000 guests.
After touring the central monument, president Kalam then gave a speech on where Akshardham fits with society, and finished by saying,
"Pramukh Swamiji Maharaj has inspired thousands of people across the country and abroad and brought together the best of the minds for creating a beautiful cultural complex. It has become a place of education, experience and enlightenment. It creatively blends the traditional stone art and architecture, Indian culture and civilization, ancient values and wisdom and the best of modern media and technology. Multiple layers of this complex expresses the strength of the mind, willpower of the human being, indomitable spirit, flowering kindness, fusion of scientific and medical talent, myriad colors of varied cultures and ultimately the power of knowledge. In essence, it is a dynamic complex with lively images.... Akshardham has happened at the dawn of 21st century with the commitment and dedication of one million volunteers. What has happened today at Akshardham inspires me and gives me the confidence that we can do it? The realization of developed India is certainly possible before 2020 with the millions of ignited minds like you."
Prime Minister Singh followed by hoping that this would usher in religious tolerance and praised the architecture of the complex. He made note of it becoming a future landmark of India.
L. K. Advani called it "the most unique monument of the world."
Pramukh Swami Maharaj ended the night's speeches and expressed the wish that, "In this Akshardham, may one and all find inspiration to mould their lives and may their lives become divine. Such is my prayer to God."

The new garbhagruh includes a decorated, canopied sihasan, upon which the murti of Swaminarayan rests and features intricate carvings and gold-leafed designs.
