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 don't see the point, just like T.V. How long do you really spend in there anyway. Maybe once in a blue moon it would be nice but really? To be perfectly honest I don't understand the fascination with the huge bathrooms that need hours to clean, I would rather save that square footage and use it for something I would actually need like a bigger walk-in closet for instance. I live in MCM house we have 3 bathrooms all small and I love them. They are easy to clean look great and what we have are nice big rooms that actually function well.

Absolutely no problem changing up the carpet. Things to watch for......make the transition in a doorway, an opening or along a visual break in the rooms (like the corners of the walls). I would stay in the same colour range, but just go to the other end of the spectrum rather than change the colour completely.....like light grey going to dark grey, not light grey going to navy blue. You want the separation but an easy transition on the eyes.

Led lighting running on both sides of each of the beams - you can buy it in strips. I would go for a bright white but you can even get it in colours and or changing colours. I would also do the same along the floor under the cabinets and perhaps between the upper cabinets and bench top.
