Enabling works have begun on the $6.5bn (AED24bn) Aljada development.
Occupying an area of 2.2km2 (220ha), the Aljada urban district will be one of Sharjah's largest real estate developments upon completion.
A groundbreaking ceremony held for Aljada was attended by HE Sheikh Sultan bin Ahmed Al Qasimi, chairman of Arada, and HRH Prince Khaled bin Alwaleed bin Talal AlSaud, vice chairman of Arada.
Phase 1 of Aljada is on track to be handed over by the end of 2019, Arada revealed, adding that full completion was due by 2025.
Arada announced earlier this month that it had signed a management agreement with Emaar Hospitality Group to bring the Address Aljada Sharjah, Vida Aljada Sharjah, and Rove Aljada hotels to the megaproject.
These details were revealed following Arada's launch of East Village, a residential community within the Aljada master development.
Comprising 15 buildings, each of which features around 150 units, East Village will offer studios and one-bedroom apartments, with handovers due by the end of 2020.
East Village is located close to Aljada's 50ha (500,000m2) commercial hub, named Business Park, and University City, one of the region's largest education complexes.
Arada revealed that East Village would be a "creative residential community" targeted at "the younger generation", including students, single tenants, sole couples, and professionals entering the job market for the first time.
The project's official launch is expected at Cityscape Abu Dhabi, the exhibition that will begin at Abu Dhabi National Exhibition Centre (ADNEC) tomorrow, and run until 19 April, 2018.
Commenting on the development, HE Sheikh Sultan bin Ahmed Al Qasimi, said: "It is our hope that East Village will be a haven for young people taking their first steps into adult life.
"They are our greatest asset, and we believe that this new community will provide the next generation with a space that will allow their creativity to flourish.
"At the same time, we are also pleased to announce that work on the Aljada masterplan has now begun on schedule.
"This is in line with Arada's promise to our buyers to deliver their homes on time and to an exceptional level of quality."
HRH Prince Khaled bin Alwaleed bin Talal, added: "Young people around the world, and increasingly across the GCC, are now playing an individual role in responsible living and environmentally conscious spending.
"We're doing our part by working to position Aljada as a sustainability benchmark in the Middle East, with best-practice techniques and new technologies implemented right the way through the city.
"We’ll also be focusing on sustainability at East Village, a community dedicated to a generation that demands an exceptional quality of life that at the same time respects the environment."
