You can do something free standing. Here's an all metal on I did last year. It's on a commercial property so material would be a little large for a residential house, but it would be scaled down.
Yea, that’s the existing patio that there extending concrete from, I feel the same way about shad and temporarily we’re just gunna do canopy tables with chairs and eventually build a bungalow that extends off the patio towards the edge of the pool. The cost is too much to extend the patio roof.
