Inspired from

The sketch consists of simple circular and straight shapes

The final design is inspired from this structure inspired from apple peal I changed this structure by making the building taller and bigger so that its more appropriate for a youth zone

Before developing this design to the new one I drew a section as if the building would have been cut in half

The stairs inside will be in a spiral shape as I want there to be space for an elevator to be place right in the middle so that it wont take up to much space

The stairs will be made from cement, iron, metals and wood

The stairs have to fun looking but safe for children because there will be lots of people going up and down these stairs

There will be many windows so that there will be natural light , which would help save electricity and its more sustainable

The walls have to be sound proof and be thick because it is placed in a park so the outside noise has to be blocked aswell as the inside noise for the outside

I really like how the spiral stairs around the elevator look like so I will be using that in my final design

This is the outcome of the design on sketchup

I think that the final design should be a little bit more complex in order to express enthusiasm and fun especially because its for a youth zone I will also be adding more colour
