You have to be carefull with the wood.
It can mold very easily so you need to stain and varnish it.
Make sure most of it is fully screened too, atleast four sides.
Other than that I love building things and it is a fun weekend project.
Just make sure you dont wing it.
You dont want to waste a bunch of money.
Also, make sure you use an aluminum screen because crickets can chew a hole in porch screen.
-good luck
