Does This Cage Layout Look Good?

I think there would need to be grids between the base uprights on the floor to make the foundations more ridged and add overall cage stability, otherwise they could just kick out overtime from the downward bearing load.

We have got a 5x2 cage and we haven't got grids between the base uprights on the floor but we haven't had any issues like that.

Mine love their loft, and run up and down the tunnel ramp quite happily. It's good when one is in a strop too!

I am so glad that you went for a 6 X 2 size instead of the 1 X 3 size as in the link you posted. Your 2 girls will be so happy in their huge new cage.
1 X 3 is nowhere near big enough for two even with 3 tiers. There's just not enough space to run about, and with furniture inside as well, it would be terribly cramped.
You will also find that one level is much easier to clean. Well done, you!
