Here are step by step instructions to build a swimming pool and diving board out of basic lego pieces. Pictures are also available for your convenience.
Step 1: Step 1- Building the Perimeter of the Pool
On 16 X 16 green platform build the perimeter of the pool by using white Lego pieces. The perimeter should be 10 X 16 using pieces 2 spaces wide (see picture). Make the perimeter 2 blocks tall. Note: Keep an opening 7 spaces in on both sides that is 2X2. This will be used for the diving board!
