GROWTH at a Formula One and supercar exhaust manufacturer has prompted expansion to a larger factory in Thame.

Primary Designs has enjoyed increased demand from F1 and bosses say the decision to increase its range for Ferraris, Porsches and other supercars, as well as developing entirely new sectors, will mean more jobs.

Founder Pat Barrett, formerly an engineer at the Williams F1 team, said the £100,000 move also gave the firm scope to expand into the aerospace, defence and marine sectors.

The company now employs 15 people at the Thame Park Business Centre.
