Firstly thinking the water butt has to move as it is not attached to any downpipe that I can see.
Also wondering is there a reason for the two levels of patio (paving outside back door and french windows) - could the higher one be dropped to the lower level - it looks like it may be blocking air vents or other end raised if air vents not an issue (just noticed the step down from patio doors!) With a level patio, you could put an attractive open work (so you don't lose too much light) fence and gate up so a toodler could be confined to the patio in safety - a height that is too high for toddlers to scale but still gives you a view of the garden!
Is the whole garden sloped?
I think that wide shallow steps would be safer with a hand rail that incorporates a high and low rail for adults and children (hope that makes sense) to get down to the garden.
I would remove all the rubble at the base of your retaining wall and plant some plants there instead.
Is ther anything in the garden? Do the steps down lead to a path?
