I'm a novice woodworker and my tools are modest. Also I am limited in how much time I can dedicate to ideas like this one that I come up with. So , speed and costs are important. But , I am doing this for the experience and try to get out of the building process what I can.
I built this for a patio because the weather conditions of South Florida can make a mess of wood outside after only a few years. Also , because of the local mosquito problem. This was a trade-off to making a real tree-house or play fort outside.
The photos are pretty self explanatory as to how it was put together. I am posting this because it may give others an idea of how to make a playhouse/fort for their kids . One that isn't outside so the kids can use/play with it more often because it is more accessible.
