Construction work is underway for the Shaza Hotel and Resort in Salalah, it was revealed.
The five-star facility is due to open in Q2 2018.
Meanwhile, Mysk by Shaza in Al Mouj, Muscat, has also commenced operations.
These details were revealed by Sheikh Salim bin Ahmed al-Ghazali, chairman of Golden Group Holding, which recently signed a management agreement for Mövenpick Hotel Muscat Airport.
The four-star hotel is located within a mixed-use development that spans 16,000m2, is worth $155.9m (OMR60m), and also includes offices, luxury apartments, and retail outlets.
Mövenpick Muscat includes 250 hotel rooms, 115 serviced apartments, two restaurants, meeting rooms, and a wellness and leisure facility, in addition to a conference and convention hall with the capacity for 1,000 people, ONA reported.
Al-Ghazali added that the four-star Rayhaan by Rotana and Hotel Centro Sohar projects are "in advanced stages of design", adding that their development teams were "working tirelessly" to begin construction in the near future.
Hospitality development has noted significant growth in the sultanate this year.
The Crowne Plaza Muscat hotel at Oman Convention and Exhibition Centre (OCEC), worth $96m (OMR37m), was inaugurated by Omran, Oman’s tourism development company, this November.
Crowne Plaza Muscat OCEC comprises 296 rooms, in addition to meeting, event, and food and beverage (F&B) facilities.
Peter Walichnowski, the chief executive officer of Omran, said the government agency had "witnessed great success" since the opening of OCEC's exhibition halls in October 2016.
He added: "Developed to align with Oman’s vision to strengthen and diversify the national economy, the OCEC project aims to accelerate the capacity, scope, and potential of the tourism sector in the sultanate.
"We have more than 50 global and regional events scheduled, and it is with great pride that we can now offer accommodation at the Crowne Plaza Muscat OCEC."
The four-star hotel is the first of three to open within OCEC, which forms the first phase of Madinat Al Irfan district.
A five-star, JW Marriott-branded hotel, and the OCEC Convention Centre facility, are due to open in the district next year.
