THE £75m development of Darlington's West Park will take a further step forward today with the exchange of contracts for a new 85-bed mental health unit.

County Durham and Darlington Priority Services NHS Trust and developer Bussey and Armstrong Projects Ltd, will exchange conditional contracts for the purchase of land for the new facility on the West Park development site at Faverdale, Darlington.

The development will also include 600 homes, 33 acres of parkland and sporting and recreation facilities.

The Commercial Property team of Blackett Hart and Pratt Solicitors, in Darlington, is acting for Bussey and Armstrong Projects on the development.

Sonia Hunter, partner at Blackett Hart and Pratt, said: "We are delighted to be assisting Bussey and Armstrong Projects in this landmark development, which we understand is the largest in the town's history."

Once planning permission is granted, reclamation of the former Darchem chemical plant will commence early next year, with the NHS trust starting construction in mid 2003.
