Police Scotland could be the newest addition to the Linlithgow Partnership Centre which is due to open early next year.
West Lothian Council Executive Committee has approved proposals for a 25-year lease of space for Police Scotland and a provisional agreement has been made.
However it is subject to Scottish Police Authority approval in August this year.
Work started on the £3.9 million project to transform County Buildings in May and when it is completed early next year the new partnership centre will provide first class community facilities in the heart of the town centre.
Council Leader John McGinty said: “It has been anticipated that Police Scotland would take advantage of the benefits of co-locating at the new Linlithgow Partnership so it is an important step forward that a lease agreement has been approved by West Lothian Council.
“The next stage is for the proposals to be approved by the Scottish Police Authority.
“The refurbishment and improvement works will ensure the building is multi-functional, modern and fit for purpose.
“By investing nearly £4 million in the new Linlithgow Partnership Centre, we are maximising the building’s use, delivering value for money and improving services for customers.
“This significant project by West Lothian Council builds upon a larger programme of investment in Linlithgow, such as improved sports facilities with the town.
“Linlithgow Partnership Centre will enhance the town centre and act as a one stop shop and community hub for local residents and groups.”
The car park at the rear of the building, which is located on Linlithgow’s High Street, was closed last December to allow work to the interior of the building to take place.
