Was surpised to see Fairlawn School in there as it doesn't look much different from many other schools from the outside (never been inside it admittedly). According to English Heritage:

SUMMARY OF IMPORTANCE: Fairlawn School, built between 1955-57 to the designs of Peter Moro and Michael Mellish, is of special architectural interest on account of its highly innovative plan form, expressed by the grouping of the two elements accommodating the higher and lower schools around a central access core, its creative and diverse use of materials and the child focused emphasis of its design, most clearly expressed in the diminutive proportions of the infant school classroom detail and the level surfacing of the connecting corridors. It is also one of only three schools produced by Peter Moro, an internationally renowned Modernist architect of the post-war era. Furthermore, It is one of a small group among thousands of post-war schools recognised as being of national importance for their architectural innovation and creative expression in the post-war period.

So there!
