Exeter contractor Rok Property Solutions made a pre-tax profit of £3.4m for the six months to 30 June, an increase of 94% on the same period last year.
Turnover rose even more sharply to £171.8m, an increase of 157% on the first half of last year. The firm has set itself a target to reach the £1bn-turnover mark by 2007.

Chairman Bob Carlton-Porter said that the jumps in profit and turnover were a direct result of the acquisition of Llewellyn last September for £16.2m.

He said: "These increases were contributed to by Llewellyn, whose performance has exceeded our expectations. Llewellyn's construction turnover and operating profit before goodwill for the first half were driven to £76.1m and £1.2m respectively."

ROK announced that it has appointed Ashley Martin to the board as finance director. Martin was finance director at media group Tempus. Carlton-Porter said: "Ashley brings with him a wealth of experience of building businesses by acquisition."
