You probably don't need to turn over the soil--probably shouldn't on a steep slope. Talk with your local experts about the best way to convert your paddock. Maybe there are enough native wildflowers growing in there that you could manage by not mowing. Here in the US Midwest we often solarize the soil by covering it with clear plastic sealed all around--this takes a full summer. I have also killed grass by covering it with a tarp for a whole year. For paths I have just laid newspaper, wetted it, and then covered it with mulch. So, it really depends on how big the area is that you are considering. Do find an expert on your area.

I won't bother with lattice, barrels are partially obscured from the street by fencing and if I put it up I would have to work around the lattice in order to turn the valves for water. If I can just make better use of collected water I'll be happy. We are at the end of our growing season so I should be cleaning up the garden and putting it to bed for the winter, just can't seem to get motivated. We had our first frost last week. Usually, our average early frost date is 1 November. I got almost no produce from garden this year, but there is always next year. Chookchook2 I've seen some of those decorative metal panels and they are gorgeous, sure hope your budget will allow you to get some before too long. Most of our state has been on fire for a good part of the summer. The closest is across the river from us and they have been battling it for almost a month. Some friends have had to evacuate repeatedly. We've only been concerned once, a small grass fire on our side of the river on a day we had wind gusts up to 65mph. Fortunately, it was put out quickly. Australia and New Zealand have both sent firefighters to help with the blazes. I can't begin to tell you how appreciative we are. The closest fire was fought for almost a week by local volunteers only as there were no other resources available. They were all on other fires. The Army National Guard (reserve troops) were called out to help with support duties and for the first time ever the federal Department of Natural Resources (DNR) asked for civilian volunteers to help with non firefighting tasks, cutting fire breaks, moving supplies etc.

Alternatively, if you just want to get the water marks out of the wood: Set an iron to warm (not hot) and allow it to heat. Lay a cotton napkin or tee shirt over the water stain. Iron the stain through the cloth for 5-10 seconds, then remove the heat for 20-30 seconds. Repeat as necessary, buffing lightly with the cloth after every 2-3 heat cycles. A hair dryer may used instead of the iron. Set it to medium heat and hold 2-4 inches from the stain. Buff the stain with the napkin or tee shirt as you heat the wood.

I would clean up first. Especially the stuff growing in the paving. Then get gardening with pot plants and start experimenting with different plants and the positions. See what you like and if you can keep it alive! Our house has the sun setting over the back fence and we've done a few inexpensive things to reduce that issue (most expensive were outdoor blinds around the verandah) but for most of the year we just don't want to be out there. It is hard work to keep the plants going in summer, there is a lot of sand due to the difficulty in keeping lawn alive and it is just bloody hot. So, that's why I'm saying clean up, start gardening small and see how you go before committing to structures that might not address the real issues you have with the yard. Just my 2 cents! :)
