In an update to the Scottish Parliament’s economy, energy and tourism committee, Ms Hyslop confirmed a private investor is expected to submit a planning application to significantly enhance existing production facilities at Wardpark Studios to create a TV and film studio complete with six sound stages, production offices, ancillary spaces and a back lot.

Already comprising 48,000 square feet across four sound stages, Wardpark Studios has been used for the production of the first and second series of Sony’s award-winning historical drama Outlander.

Plans to expand the facilities to provide an additional 30,000 square feet across two new 50 foot-high sound stages have been the subject of detailed negotiations between its owners Wardpark Studios Limited and the Film Studio Delivery Group (FSDG), comprising the Scottish Government, Scottish Enterprise and Creative Scotland.

Negotiations around public sector support for the commercial venture, which must comply with strict EU competition rules, are now at an advanced stage. While a deal has not yet been finalised, Wardpark Studios Limited’s decision to seek planning consent is a firm indication of the site owner’s commitment to the project. It’s expected the planning application will be submitted to North Lanarkshire Council later this week.

If the negotiations reach a successful conclusion and planning permission is granted, it will pave the way for the facilities at Wardpark to be completely overhauled.

The FSDG also confirmed today that conversations are also underway with potential private sector investors in relation to additional studio sites in Scotland, and the group remains keen to hear new proposals.

The FSDG’s work to deliver enhanced screen studio infrastructure forms part of a wider public sector commitment to strengthen the Scottish screen sector.

Three new funds totalling £4.75 million were introduced in 2015, building on the record £24.1m of public funds awarded to support the screen sector in 2014/15.

This week Creative Scotland confirmed it has made its first conditional offers from the new £1.75m Production Growth Fund. Totalling more than £800,000, these offers will support two productions to film in Scotland. A third application to the Production Growth Fund is currently under consideration.

A new Screen Sector Leadership Group has also been established and Skills Development Scotland recently published a Skills Investment Plan for Scotland’s creative industries.

Culture secretary Fiona Hyslop said: “Wardpark Studios Limited’s decision to seek planning consent for new studio facilities in Cumbernauld marks an important milestone in our work to strengthen the Scottish screen sector.

“Our work to ensure additional screen infrastructure is developed in Scotland and the new funds we have set up, are helping us to build on this growth – incentivising filmmakers from around the world to come and realise their projects in Scotland.”

Natalie Usher, Creative Scotland’s director of screen, said: “In order to support local productions and attract UK and international productions, Scotland needs a full range of options for stage space and production offices: purpose-built studio facilities; full-time conversions such as the space currently used by Outlander at Wardpark; and build space like The Pyramids in Bathgate, and the Pelamis Building in Leith.

“Converted and build space in Scotland that is currently being marketed compares favourably with similar space marketed by other UK nations, but we also need purpose-built space in order to compete effectively. We are working through the FSDG to realise a purpose-built studio facility in addition to the existing full time converted space at Wardpark. We continue to investigate other potential options where there is interest from the market and appetite from private investors.”

David Smith, director of creative industries at Scottish Enterprise, said: “Wardpark Studios’ plans remain at a critical stage of consideration but I believe their decision to apply for planning consent to increase the size and scale of the existing facilities in Cumbernauld illustrates their long-term commitment to operate world-class studio facilities in Scotland.

“We remain absolutely committed to doing whatever we can within EU competition rules to ensure additional screen infrastructure is developed in Scotland.”

Terry Thomson, chairman of Wardpark Studios Limited, added: “We want to enhance the existing four sound stages with a further two stages to expand and grow productions using the facility.

“With each production using the site, the benefits to the local and national economy are increased, reaching far beyond simply the studio and deep into the supply chain.

“Lighting and rigging suppliers, local builders’ merchants, landscaping suppliers, transport suppliers and many others provide the products and services that ensure these global productions can be made right here in Scotland.

“Our planning application seeks to make the most of the existing facilities and land available. While we’ve reached agreement in principle with Scottish Enterprise and the Film Studio Delivery Group on possible financial support, there remain a few commercial details still to be finalised before we can move ahead with our plans.”
