This is my first time building anything, and it was so fun, minus the million trips to home depot! I had to modify the original plans to fit over a queen size bed, and I actually built the roof that is part of the plans, but we decided to use fabric for the roof to let light in. For now, it's a convertible fort, ha!
I also added shelves along the back wall, similar to the onces done by Jamie Costiglio. I thought it was a good way to incorporate storage for some action figures. Plus, I left a space in the front open so that my son could jump from the fort to his bed. Underneath I strung up some lights with small command hooks and they're connected to a smart switch so we can ensure they aren't left on all the time.
This took me significantly longer than it might take a skilled builder because it was my first time. It was a solid 3 days of work - a full weekend and then one day the next weekend.
Overall this was such a fun build - now to add a rock wall on the side! :)
