Any duck house ideas?

[Pluto8]

Does anybody have ideas on what cheap and affordable duck houses i could use for our coop. What could we add as well? I've attached a picture of the coop.

https://morningchores.com/duck-house-plans/ might find some ideas here some are fancy others more down to earth. Main thing is safety and ventilation. There is a pallet house which would be inexpensive if you have a source for free pallets.
