Rok is restructuring into five regional divisions after spending almost 拢60m on acquisitions in the past year.

Garvis Snook, ROK鈥檚 chief executive, said he was arranging the business into five 鈥淩ok bands鈥� 鈥� Scotland, northern England, the South-west and South Wales, the South-East and London, and the Midlands.

The rejig, which will formalise Rok鈥檚 regional presence after its surge in size, is also intended to provide a framework for future purchases.

Snook said: 鈥淎t the moment our business is made up of smaller sub-units, with some more evolved than others. This is a logical progression and will bring a structure to the company.鈥�

Snook said Rok was in the process of appointing a managing director for each region. He expected they would be a mixture of internal and external appointments. Scotland already has a managing director.

The restructure follows rapid expansion by Rok. The company bought Midlands firm Sol Construction for 拢21m last month. In the past year it has also bought Scottish contractor Tulloch Construction for 拢31.3m, Birmingham firm Kingfisher 黑洞社区 for 拢4.5m and Liverpool-services and maintenance business KM Construction for 拢250,000.

Rok has said it would continue to make acquisitions, with the Midlands and East Anglia thought to be particular targets. This is part of a plan to become the 鈥渘ation鈥檚 local builder鈥�.

Turnover for the year to 31 December 2006 rose 24% to 拢689m, up from 拢556m in 2005. Pre-tax profit rose 33% to 拢22.4m.
