Do you need all that patio in front of house?
I ask as it may be an idea to leave a double row of slabs then remove the rest to create more room, with a series of stepping stones down to the end, then i'd plan a straight line across, from right-to-left to make a triangular patch with a raised bed for a small tree - an acer is always good for those spots as their tolerant of low light and grow high enough to hide the fence while not overshadowing the rest of a small garden. Alpine plants, sempervivum, lavender, Coleus, foxglove, ferns provide a wide range of colour and height to create a distinctive array all year round but try not to go mad with birchbark weed suppressant as birds will rough it up to make the place untidy. A small garden like that won't require much maintenance anyway.
Another way could be to leave a row of three slabs on the patio, but curving a wavy line from side-to-side in order to avoid the curious discrepancy between the left and right side of your fence. A touch of Ronseal on those panels would be a good diea to freshen them up.
Ronseal Clear Decking is my go-to for cleaning up tired wood, and a planter at the far end to the right of the gate can provide enough room for herbs or flowers to brighten up the place and provide fun for insects and bees.
