Nice solid Gazebo.  Bought some curtains in addition to the mosquito screens that came with it and also some ceiling heaters with remote and a dimmer swag light.   Also suggest to buy some sand bag anchors (see photo) so you need not require anchor bolts into the concrete.   Has had several hard rains and winds gusts up to 35mph and it didn't move an inch.  Only design quibble is that the ceiling has an opening that in theory bugs could enter from the top.  I used it to host an outdoor movie watch party with a portable 120" screen and 4K HD short throw projector.
