I opted for this size gazebo because it is just small enough to not require a permit in our municipality.  The quality of construction is outstanding and it very, very solid.  We paid for the installation at the time of ordering.  The guys were quick and efficient and did in 2-3 hours what would have likely taken me 2-3 days!  The only thing to be aware of is that the packages where delivered to our driveway and where EXTREMELY heavy to move to a more secure location while we waited for our install appointment.  Plan on having some very strong people around to move them!
