PARENTS and governors are uniting in their opposition to the temporary expansion of a primary school in Acton, claiming children will be packed in like 'sardines in a can'.
The number of pupils at Derwentwater Primary, in Shakespeare Road, could be increased from 90 to 120 from September.
The school already has the smallest square metre space per child compared with all other schools in Acton. The whole school community is rallying to back the DARE campaign - Derwentwater Action to Reject Expansion.
Sophie Harrowes, chairwoman of governors, said: "It is already one of the most congested schools in the borough. External space is extremely limited and there's no access to any other outdoor space such as playing fields for PE or playtime and expansion will further restrict the opportunities available to children.
"We cannot, in all conscience, support this denuding of our pupils' educational opportunities. Our 2010 school priorities are to improve the quality of teaching and to raise the achievement of vulnerable groups and adding more children into a space that is already challenging to administer isn't going to make a positive contribution to these targets.
"We don't have a limitless ability to expand and we cannot endorse a project we consider is likely to have a significant and detrimental effect on the learning, facilities and achievement of our children."
Alex Watson, a parent, said: "We are so incredibly under pressure in terms of space - we are at full capacity and it's simply not feasible to expand when we are bursting at the seams.
"We have the least amount of space per child and the reception year is already taking on extra pupils. Children need space to run around in and the school already operates a shift system in the canteen so meals have to be eaten within 20 minutes, there is no designated art room, science laboratory or library and the school can't organise whole school events.
"We're also concerned about access to the school, which is through a small residential road and if more parents drop their children off, it could be dangerous."
An Ealing Council spokesman said: "This is far from being a done deal. We are currently looking at a range of options to cater for the growing demand for school places in this area and we will discuss all options with schools and parents."
