Last month I assembled on our deck an aluminum gazebo, purchased from Costco.
It was delivered on a double pallet of heavy cartons:

I lugged them over to the deck:

Lots of small parts:

It includes sliding insect screens. Here I’m assembling one of them:

Screens somewhat done:

However, our deck isn’t completely flat (like everything else in this house), so I used a router to cut a notch in the deck for the screen track:

Finished installation:

We purchased a rug for under the table, and new seat cushions (only two chairs out here):

While the screens provide some sun filtering, it can still be very bright as the sun heads towards the horizon, so I added a retractable shade:

I also installed a covered power cord up a leg for lights etc:

Here’s the top, with power for a string of lights, an Amazon Echo, and a pair of speakers:

Echo, light, speaker:

The Echo streams music and other functions through the speakers. The color-changing lights run around the edge of the roof.
I also added a power strip zip-tied under the table, providing convenient outlets and USB power:

All pleasant additions to our deck, to make working and eating outside more comfortable and enjoyable:

Tomorrow, another addition!
