Lisburn's first hotel is to be expanded just two years after it first opened.
The £2m project will see the Premier Inn host 30 new bedrooms and create 20 new jobs.
The complex was developed by Magherafelt-based Conway Group and is operated by the UK's largest hotel group, Whitbread PLC and opened in September 2009.
The opening of the hotel, on the Hillsborough Road, marked a £10m investment by the Conway Group, and saw the creation of 60 full and part-time jobs in the city.
Established in 1974, the group currently employs around 600 people in Northern Ireland.
Des Taggart of Conway Group said that the hotel has proved very popular over the past two years.
"This new investment shows our continued commitment to Lisburn and to developing the cty's business and tourism potential," he said.
"We aim to commence works on the extension upon receipt of planning permission and hope to create 20 new jobs and bring in additional tourism revenue to the city."
Jill Moore, manager of Premier Inn Lisburn, said that the expansion will help meet growing demand. "When we opened the Premier Inn in 2009 we knew that Lisburn had great potential and this extension is clear recognition of this.
"Over the past two years we have welcomed 55,000 visitors to the Lisburn hotel. With our reputation for quality and this increased capacity, we look forward to welcoming many more.
Keith Freeman, the head of Premier Inn Northern Ireland, added that the group plans more expansion.
The project has the backing of First Minister Peter Robinson and Minister of the Environment Edwin Poots.
Mr Poots said that the opening of the Premier Inn Lisburn marked a new phase in the development of the city as a centre for tourism and commerce.
