The windows themselves have an interesting design that mirror the archway detail on the top. They are built in large numbers and are the main feature of the design. 

The other smaller, though no less important details, are around the downpipes that have designs pressed into them. Also the spouting has boxed features that complement the design of the building as a whole.  

The school was very happy with the timeframe this was carried out in and the finish quality. The building now looks fresh and crisp.
