"Garden shed. Happy with the new shed-looks great, easy to put together good instructions relatively easy to follow. Removing the plastic film was very time consuming, in the end could not remove some of it. Quick delivery. We were 9 screws short, not a deal breaker, however made it awkward to finish. Very good shed."
