The San Antonio Hotel in Bugibba is set to become the second biggest hotel in Malta, with a €28m project seeing the number of beds growing to over 1,500.
The project is being undertaken by the Seabank Group.
The works were taken in hand in November, when the hotel temporarily closed down. Guests are set to start returning on March 15.
700 workers from 30 companies are working round the clock on the project which involves the building of a new block and new floors.
The hotel will have 585 rooms, including 80 apartments along with four swimming pools and eco-friendly lighting systems. It currently has 285 rooms.
Prime Minister Joseph Muscat toured the hotel this morning.
Seabank group director Silvio Debono said that in the coming weeks, the company would unveil its brand of hotels which will also include the Seabank in Mellieha. He said the group has invested €68 million in its hotels over the past two years.
The extension of the San Antonio will create 100 new full-time and part-time jobs from the current 130.
