Claremont Group Interiors has completed the fit-out of Vindon Scientific's new premises at the 420-acre Kingsway Business Park development in Rochdale.
The Warrington-based fit-out specialists completed on time and budget.
Ken Bundy, designer at Claremont, said: "The project offered an usual challenge of uniting the clinical side of Vindon's business operations, with the warmer customer-facing side of the business."
Claremont recently reported it had reached a turnover of £17m in the first half of the 2008/09 financial year and hopes to reach its target of £28m.
Staff numbers had risen from 80 to 90 last year, in line with the growing order book.
Vindon Scientific has relocated to Kingsway from its original site in Diggle, Oldham.
