HI -- The simple thing is to get some of the plastic garden lath panels and fasten them to the railings. They come in 4x8 panels I think. A more permanent solution is to replace the two railings and install the frosted plastic or tempered glass panels to about the 5 ft. height or the full height which ever you prefer. I would fill in if it was me. Or you can just hang up some polyester patio drapes or drapes made of outdoor fabric. Those you can just pull closed when you need to

Thanks it is the biggest covered patio i have tackled + we had to follow the angle of the existing pool. Nearly had a mutiny from the roofies when they saw the length of the roof sheets.

the photo of you chosen style would be very easy to add to your home but a narrow verandah will not be much use for anything more than a couple of chairs so my first thought would be to suggest converting the existing carport into extra indoor out door living areas with a new carport added to the side or a double steel garage towards the fence could be more cost effective OR a square deck with gabled roof (with or without a verandah along in front of the master bedroom) would have more space for a barbq table and chairs

Wow there are so many angles on the rooves (roofs?)... I don't know the right or best option but I imagine the deck being curved, to create some interest. I want bug chunky timbers in dark stain like recycled wharf beams or railway sleepers. I think start by removing the little roof over the porch and opening it up flush with the brick wall of the front door. Then install chunky beams (wood or steel) that fly quite high and straight over the void between the 2 sides of the house. I would use a polycarbonate roof in that area to let extra light through and not make the house entrance too dark. The area behind the carport where the deck is level with the rear of house, I would have a solid roof that matching the pitch of the back of the house, or even not have a roof at all. I would leave the entry deck area and the curve unprotected. My only question is this... is this an area you would hang out seeing its quite disconnected from the living areas? perhaps having a more ramp like entrance with interesting trees in the void area and making a matching deck on the other side might work. I just feel if its only going to be an entrance its a big capital investment and an expensive exercise with all the roofing.
