This is the first glimpse of a new languages and humanities centre due to be created at a Penwortham school.
The £1m project is the latest in a rolling programme of improvements at Priory Academy.
The Academy, in Crow Hills Road, is having the existing facilities remodelled and extensively updated.
The work will involve creating of bright, open classrooms, a new feature entrance and heating system and major improvements to the fabric of the building.
The centre has been designed by award-winning Preston firm Cassidy and Ashton and Preston-based Conlon Construction is due to start building work later this month.
The project is expected to be completed by next Easter.
Funding has come from the school’s own budget and the Academies Trust.
Headteacher Jim Hourigan said: “The school has been here for 60 years and obviously some of it is still the original building.
“It’s time to move things forward to reflect the current climate with more learning space and to be more flexible.”
He added that school had seen a sharp rise in students achieving grades A*-C in maths and English.
Mr Hourigan added:“As a school we are going from strength to strength and the new buildings will help us continue to build for the future.
“It’s for humanities and languages but there will also be a music studio and a performing area.”
Over the past decade the Crow Hills Road site has seen significant rebuilding work at, including the new ICT rooms, the science block, a state-of-the art technology centre.
Alistair Baines, director at Cassidy and Ashton, said: “Over the last decade, Priory has undergone major redevelopment in recognition of its status as a specialist sport and technology college.
“The new languages and humanities building will add to the school’s long list of top-class facilities, and our designs will incorporate the same use of bright open spaces to create a truly modern learning environment.”
