Log Cabins for Kids Playground

Have a very active twins takes my time and energy. They move on and on until I feel tired. I’ve not got the idea to make them calm. Sometimes I am intending to take a moment to rest, but impossible if they keep playing. I have to watch them all the time and it was exhausting. Finally i got the idea to build them a log cabins to play. Incidentally there is an empty area next to my house.
Following is the log cabin next door, my twins are always happy to play in it.
Miraculously now they can sleep on its own without accompanied me. Because I provide to their mattresses in it.
Thanks to the log cabin, I can finally take a break from an exhausting routine. And I also can easily monitor them from the main house. I’m not worried about leaving them to play there, because the cabin is very safe for them.
