Howdens are the latest addition to the refurbished Preston Trade Park.
The operator has taken Unit 2, which measures 6,415 sq ft to expand its existing operation. Other operators include Benchmarx and Euro Car Parts.
The remaining two units, 5 and 6 are both under offer to national and regional operators.
Barrie Cochrane at Cheetham & Mortimer commented "this recent letting demonstrates the quality of the scheme refurbishment to attract national operators".
On completion, the scheme will be fully let. Cheetham & Mortimer are joint letting agents for the scheme with Kenney Moore.
