CBRE has let a 6,500 sq ft unit at Jolivet Investments' Moorgate Point development in Knowsley to builder and civil engineer J Murphy & Sons.
The firm has agreed a three-year lease having consolidated its two offices in Golborne and Haydock.
Moorgate Point is a two-storey office building offering fully refurbished office accommodation in a variety of suite sizes from 88 to 14,500 sq ft.
Jolivet Investments, Guernsey, acquired the building in 2011.
Neil Kirkham, associate director at CBRE, said: "Moorgate Point has enjoyed great success over the last six months not least with the enterprise centre, which occupies part of the first floor of the building offering very flexible, short term lettings in self contained cellular offices, attracting 11 new tenants."
Matthews & Goodman is the joint letting agent.
