Plans for a new science block to be built at Ripley St Thomas CE Academy have been submitted to Lancaster City Council.
The school wants to demolish an existing Portacabin and build a new single storey science classroom building in its place.
The proposed site for the new science laboratories is next to the south east entrance gates, between the drama department, the swimming pool building and the old gym hall.
There are currently a number of science labs in this area of the school.
The existing buildings was erected as temporary accommodation but there is now a need to increase the science department due to changes in the national curriculum. The temporary buildings are no longer deemed suitable.
The new building will provide much needed additional science labs in two purpose built classrooms.
The building will be single storey and will also contain a small plantroom.
The plans will be discussed at a future planning committee meeting.
Ripley recently developed a new Sixth Form centre to help cope with an increase in student numbers.
The school this year marked its 150th birthday and celebrated the occasion with an open air service for the whole school, which was attended by the Archbishop of York, Dr John Sentamu.
