I design this 3 different houses for my froggy hotel. the idea is each house have a hole to fit in a PVC 56mm pipe where the frogs can hide during the day.

I design them so they can be put up high or ground level with little pools for fresh water.

I prefer to set them at ground level ( with the pipe dig underground ) and surrounded with navite plants that would provide extra shed and protection.

Recomended to use PETG with supports.
