Turnover at Coalisland construction firm, Western Building Solutions, has grown by almost a third in the last year to nearly £40m.
The firm, which specialises in prefabricated and modular buildings has won a host of major contracts for schools and hospitals across the UK and Ireland.
While turnover has increased, profits at Western are also up 14 per cent - which means the company made £3.8m in the year up to April 2016.
In their recent Companies House report, directors said the future appeared positive despite a slight fall in profit from 2014.
They also said the aftermath of Brexit was posing a challenge for the company.
With 44 staff (down from 53) Western pays a wage bill of £1.9m, but also uses sub-contractors and temporary staff depending on workloads.
Earlier this year, the company was among just five Northern Ireland companies named in Investec's Mid-Market 100 - the fastest growing private mid-market companies in the UK.
