I tweaked my old walk-in design to fit your 5x10 footprint for visualization purposes—you could show it to your family so they have a better idea of what something that wide looks like when you make it human-tall.

A major draw for my family was the possibility of using the aviary for chickens/ducks or wild quail when I'm out of the picture. They thought it was too big at first, now they call it "functional yard art"

. Really hoping your family sees the beauty in happy quail and lets you pick out a spot in the yard.
