Very well made, especially for the money. The wood is NOT protected and should be sealed when you get it. We built the initial frame, got it square and then reinforced our deck under each leg so we could secure it there. My only very slight complaint is how much noise it makes when you walk across the deck/under it. Small vibrations get amplified through the metal roof. I suppose you could use a mastic tape under strategic locations to dampen some of that noise, but it's a very small complaint. The wood is pretty soft, so pay attention to how much you tighten the fasteners. Otherwise, it's very nice. Assembly is quite detailed, but progresses fine. My father-in-law and I built ours on a Saturday. Got started around 9am and finished around 3pm. After installing power and lights I started using it as a sort of outdoor office, and it's been great!
