LONDON — Titanic Studios, the production facilities in Northern Ireland where “Game of Thrones” is shot, is to add two stages as part of a £14 million ($23.5 million) upgrade.

The facilities, which sit on an eight-acre site in Belfast, received the greenlight for the expansion plans from Northern Ireland’s environment minister Mark H. Durkan on Tuesday.

Durkan said the added production capacity would help “put Belfast on the map as one of Europe’s largest film production locations.”

The extension will provide an additional 100,000 sq. ft. of production facilities, which will increase the site to more than 250,000 sq. ft.

As well as the new stages, there will also be additional production workshops and parking.

Titanic Studios incorporates Harland and Wolff shipyard’s former Paint Hall building, which has been converted into four 16,000 sq. ft. stages. The shipyard was where the ill-fated liner was built, hence the site’s name.

The Paint Hall was first used in 2007 by Walden Media and Playtone Prods. for the fantasy sci-fi adventure film “City of Ember,” and then by Universal Pictures in 2009 for medieval comedy “Your Highness.” From 2010 to 2013, it was home to seasons one to four of “Game of Thrones,” and the fifth season is shooting there now.

Two additional stages, Hurst and MacQuitty, were opened in 2012, providing 21,000 sq. ft. of space each.
