The secondary school at Enfield was a typical
PFI project, built by contractors Laing Ltd with
designs by architects ACP. The classroom

London Borough of Enfield, where the
illumination levels required were given as 300-

linear pitched rooflight down the centre to

balance the daylight.

specific floor area requirement, which

should not exceed 7 m. The room heights

were standardized at 2.985 m, with a cill

height of 0.95 m in order to ensure that the
