Gym
I will be making a gym where there is equipment and where people can go workout. I will be making the floor plan at the beginning. I then will make all the things/equipment inside the gym. Then I will place the roof on top and put the color I want.
Floor Plan
First, Make the floor plan how you want it. Put some floor and start to make the windows and structure. Add as much details as you would like to.
Equipment
You will have to make the supplies and things that I put inside the gym. I put equipment as there is in gyms. I also used code-blocks to make some of the equipment. Be creative and make it look like a gym where people can workout.
