Install a door track under the existing door track and then make four frames and screen them this way you can open it just like the door for easy access.
Home Depot sells them for $27 dollars per box of 45..........
It cost me $306 dollars for tile,glue and trowel..........and I have extra tiles if I damage any..............This is very little money and gives a great look !
The floor is Armstrong tile the type that is glued down and is holding up very well.
My car and van are parked in the garage all the time and I do a lot work in it also.
