Hurstwood sales director Mark Carling said: "Hurstwood Court offers great facilities with units benefitting from a mixture of warehouse and office space so it is no surprise that we are now fully let.
"The estate benefits from excellent transport links with M65 in easy reach and Preston, Blackburn and Burnley all within a 20 minute drive. This has been a major factor in attracting companies to the site.
"Demand for our industrial properties has been high in 2013 in general and we anticipate completing more deals at our estates across the North West over the summer."
