In my build, there is a large pool in the center surrounded by around 25 pool chairs, this build includes 4 mini-figures to pool party with, these mini figures has there own style of clothing that each of them wear, the capacity of my set is how every many people you want! But, only 25 of them can sit at a time. The pool is made of blue(water) bricks and is surrounded by white(white cement) bricks and surrounding the entire pool are green(grass) bricks.
I build this build because, Pools are iconic in this society, and Lego is awesome. So, why not combine these 2 to get an amazing build.
This would make an amazing Lego set because everyone loves lego and most people love pools, making this the golden opportunity to shine.
