I suggest that you carefully draw to scale if you want to get an idea of how it will look. Your current drawing does not seem to be to scale, the spaces on the sides of the house appear to be much wider than the space actually available. Your lot is 18.3 meters wide and the house is 14 so that leaves 4.3 or about 2 meters on each side but your drawing shows more than twice that.
At the pool area the 14 meter house width is longer than the 17.5 between the house and the edge of the land.
This is not just a little deal, we are talking meters of difference, not centimeters.
