A Moira-based architectural firm is creating 30 jobs as it opens a second factory in Portadown in a multi-million pound expansion.
McMullen Facades has been based in Co Down since it was set up in 1971 but is now opening a new manufacturing premises on Mahon Road.
The company, which employs 125 people and has annual sales of around £26m, makes glazing and specialist facades for buildings and has worked on offices and apartments in Belfast such as the Obel, the Boat and the Soloist.
The firm, which is now part of Lakesmere Group in Britain, said a boost in its order book in the London high-rise residential and commercial office market was the main driving force for the expansion.
There are around £65m worth of London projects on its books at the moment, and work on the facades will take place in the Portadown facility - set to be three times the size of the Moira premises.
It's also been securing work in the north of England as the Conservative Government's drive to create a 'Northern Powerhouse' of successful businesses gathers pace.
While around 30 staff are currently sought for Portadown, the facility will employ up to 125 people when fully up and running. That will bring its total workforce to 250.
McMullen Facades managing director Ronnie Mills said: "This is a really exciting time for McMullen Facades both in terms of the work that we are doing and the clients that we are working with.
"We pride ourselves on being at the forefront of innovation and a leader in the specialist contractors sector, which has led to significant growth in recent years - so much so that we have now outgrown our current manufacturing facility and will soon be moving to a much larger factory in Portadown, creating a number of new jobs.
"We are delighted that our expansion has been able to bring a benefit to the local community and the regional manufacturing industry.
"Our people represent some of the very best talent within the construction industry and we are committed to developing all of our staff through continuous training.
"We may be operating in the national construction market but we are very much a local company at heart and we look forward to welcoming new faces to the McMullen Facades family."
The company has worked on the Eveyln Grace Academy in London, which won the Stirling prize for architecture in 2012. Lakesmere Group has a turnover of over £125m, and has worked on high-profile projects such as the London Aquatics Centre and Heathrow Airport's terminal. McMullen Architectural Systems was founded in 1971 by Edward McMullen. His son Ted took over the business in 1979.
