My husband built this out of wood pallets for whenever we were in our backyard for long times, our dogs would have some shade and a house to lay down.
The roof is covered by a waterproof material so if it rains it won't leak inside. The house as you can see has a nice "balcony" for them. It also has wheels for easy transport but is REALLY heavy.
You could easily re-paint since is plain wood.
Pick up in Yomitan.
