Ideas for small outdoor Beardie enclosure needed

[CitrusTiger]

Hello! I am planning on building a medium-sized out door Beardie enclosure for my bearded dragon, Bobby,

My ideas so far:
3 feet wide, 2.5 feet long, 1 foot tall
Wooden "floor" or "base"
Wooden walls, with an undetermined wire or mesh for the sides (any ideas? Sharp points WILL be trimmed and melted so they will not cut him)
The top will have the majority of the undetermined wire or mesh, with a locking latch

What do you guys think? I am drawing a basic plan/sketch of what I want to build, and can maybe post that somehow

What sort of outside space do you have? How long will your dragon be in it at a time? Will they be supervised or not? You'll want to make sure to binge enough to provide shade and a cool hide area.

I'm kicking around the idea of an outdoor enclosure for nice summer days. My concept was to use 2x4s or pvc pipe to make a 4' cube - then screen the walls and ceiling with window screen or nylon mesh (to keep bugs out).
