South Wales contractor Castleoak Construction, part of £25m-turnover Castleoak plc, has landed £30m of backing for a new venture from banking giant Credit Suisse First Boston.

The £15m-turnover contractor has set up Castleoak Design Build Finance, a new company offering a one-stop building service for clients in the healthcare sector.

Castleoak chairman Melville Knight said the new business would offer a complete service for clients wanting to take the risk out of the building process. "We will find the land, design the project, build it, fit it out and then effectively sell it back to them," he said.

"The client will not have to worry about the administration of the whole process. We will do it for a fixed price agreed in a pre-sale agreement.

"The main advantage is that it gives them financial security. We will give them a fixed price with no danger of a cost overrun." He said finding the right land at the right price probably posed the greatest risk for clients.

Knight conceded that the care home market was tough at present because of cost pressures, but he believes the business has a good future.

He estimates the £30m fund, provided by Credit Suisse First Boston division UCB Healthcare, will last two years.

The firm's 40-bed residential home in Thames Ditton, Surrey is one of the DETR's Egan demonstration projects showing good practice in construction.
