Plans to expand Asquith Primary School will go out to a formal consultation event on Monday.
The expansion plan would see the school becoming a two form entry school with an 30 additional places needed for children living in the local area, especially those in Churwell.
Headteacher Gill Austerfield said: “It is a good opportunity because there will be more staff which means more expertise and more opportunities for children and parents.
“Local families will have more choice and hopefully they will be able to send their children to a primary school which is in walking distance from their homes.”
From Friday plans to develop a second building at the back of the original school which will house the key stage two pupils, will be put on the Leeds City Council website for consultation.
The expansion will happen gradually, each September over the next few years as children move up into the next class starting from reception classes this year.
Throughout Morley there is a demand for additional school places and worries have been raised before when councillors were told by education chiefs primary and secondary schools will be full by 2016.
The Leeds City Council’s Local Development Framework plan is aiming to build 5,000 new homes in the Greater Morley area.
Last month councillors were told the new housing figures will mean 1,250 new children needing primary school places and over 500 children needing spots in the secondary sector.
