My husband and I started putting this together yesterday and still have a few more house to complete it. We spent from noon - 5 with minimal interruptions assembling what we could in the garage and need a nice day to complete the rest (Wisconsin weather). It was very helpful my husband is extremely handy and has many tools. The wood its self seems a little flimsy but put together its was sturdy enough for my husband to climb up it. The instructions are very well organized as all of the pieces are labeled. You do want to stay organized when assembling. I will add another review once its completed and the kids can play on it.
