the map below shows information about a school

The picture illustrates the transformations of an area called Hogwards grammar school in the period from 2004 to 2010! Overall, it is clear that this place was well-constructed and most of the changes took place around a school building, whereas, there was a little change in its East! Specifically, in 2004, the sport field in the center of the map was reduced to give room for the construction of two new school halls in its west, in 2010! There was the demolition of a walking path between the school and the sport field, and the new roads were erected to connect three school buildings in the seven years! Due to this development, the capacity of the school was increased, from 600 students to 1000 students expectably. Another physical change is that in 2010, a car park appeared which is beside the school! Moreover, the main road in the South of the sport field was redesigned to attach two car parks between 2004 and 2010! While the old car park in the Northeast corner just experienced a tiny narrow down during the period! However, all the trees in this delineation remained unchanged in the same period
