Westlakes Science and Technology Park extension starts
Work has started on a £2.9m extension of a Cumbria business park.
Westlakes Science and Technology Park, near Whitehaven, is home to firms working in the area's energy sector.
A 2,000 sq m office block, named Pillar House, will add space for a further 200 workers and take about 12 months to complete.
The development is being part funded by the parent company of Sellafield Ltd. About 1,500 staff currently work at the site for 70 different companies.
