I spent time over my winter break from work to build this for my nine year-old. She absolutely loves it. It is much sturdier than the basic wooden loft I had in college. Now my 6YO wants one! I bought a Kreg Jig, which was a great investment to build something like this. I used a circular saw but next time around would borrow or purchase a miter/table saw for the large number of cuts required. I spent $475 in lumber, screws, nails, paint, etc which was more than I had planned, but we are happy with the result! It took me about 40 hours to build this in my basement. Great project for daddy/daughter time while school was out; she made the majority of the measurements for me! There were very slight issues with the plans but overall it was not too difficult.
