This is a dojo that I built a while ago specifically for these type of figures. I forgot the company that makes these street fighter figures.
They are not made very well, but its ok since it was a good price for a 2 pack and I am posing rather than playing with them. Both broke
while posing, though.

I used craft plywood for the walls and floor with a latex paint for the walls and a wood stain for the floor. The tiles were made by using a ruler
and utility blade, scoring a few times. The hard part was the kettlebells made from clay and an eye scew. I did the round and triangular
ones that the weightlifters use for strength. The punching bag wasn't easy either and that is what took the longest. It was made from
a small leather pouch and filled with fabric and a little sand. The chains were attached to an eyescrew with a strink tube.
