The new build at Kerr Mackie Primary School in Leeds will help utilise school space and will be used for a range of different lessons for pupils, including Art and Design Technology.
It will also be used for enrichment clubs and activities as well as for providing its wrap-around-care offer.
Assistant headteacher Jack Swanston said: "We're really optimistic that this will have a fantastic impact on our pupils and their experience during their journey at Kerr Mackie."
The opening on Thursday (December 14) coincided with the school's Winter Fair, and was visited by a number of other businesses, as well as pupils and families.
Here are 15 pictures from the Grand Opening and the Winter Fair:
